FASS Diesel Fuel Lift Pumps

May 14, 2012

Why should you consider installing an aftermarket diesel lift pump on your truck?  As diesel performance becomes a more and more mainstream part of automotive upgrading, we have conversations with many of our customers  each day about which performance diesel parts they should consider installing to get the fuel economy gains and power increases they want.  Knowing which diesel upgrades are critical from experience, even if we start off talking about diesel tuners, cold air intakes, exhausts, injectors, turbos and the like, invariably we steer the discussion to a product like a FASS Lift Pump.  Why do we always end up recommending a fuel pump, when many diesel trucks already have one in some form or other?  The answer is simple – there are several reasons.  Some so compelling, in fact, that we would feel like we had done our customers a disservice if we didn’t educate them.   Let’s look at some of  the most important.

FASS Diesel Fuel Lift Pumps1) It’s smart insurance – If you’ve ever paid to replace a set of diesel injectors, especially for a common rail diesel, you know that you can easily spend a few thousand dollars or more on a set.   A Fuel Air Separation System (FASS) lift pump can protect that investment by removing fuel contaminants like water, dirt, and air.  This protects the tip of your injection nozzles and your injectors.

2) Your truck will thank you with better performance – diesel performance is all about improving the combustion event.  Cooler air is denser, and more oxygen in the cylinder helps make more power.  Thus the popularity of diesel cold air intakes.  The better the purity and atomization of your diesel fuel, the better your combustion event will be.

3) Improved diesel fuel mileage – One of the most prevalent methods used to improve power and diesel fuel mileage today is a diesel performance chip.  And one of the most common methods performance chips employ to get greater gains in power and fuel economy is raising rail pressure.  A FASS fuel pump will give your injection pump the support it needs, providing a constant supply of fuel, and at  the correct pressure.  Whether you use a tuner or not, a FASS pump can give your truck’s fuel economy some real help.

For all these and other reasons, we feel confident recommending an aftermarket lift pump like those from FASS for every diesel truck owner on the road.  Visit Parley’s Diesel Performance to read more about the different types of pumps FASS offers, and to learn more about this important diesel upgrade.


Want to increase your diesel fuel economy?

March 5, 2012

Fass lift pumps are a great way to increase your engine performance and diesel fuel economy by removing air and water from your fuel. It is well known that as your truck moves the diesel fuel in your tank is constantly in motion. This creates multiple problems with fuel delivery to your engine. While the injection pump draws fuel from the tank it’s creating a vacuum that produces fuel vapor and as the vehicle is in motion it creates fuel vapor that is mixed with the air. Resolve that issue by installing a FASS Lift Pump from Parley’s Diesel Performance and as a added bonus you will get higher power and reduce injector tip erosion. Typical No. 2 Diesel Fuel already consists of about 10% air. That issue is compounded by dirt and other debris that can be found in a diesel fuel tank. A FASS Lift Pump will address these issues head on by meticulously filtering out such problematic air & vapor (along with other contaminants in the fuel) before it reaches your truck’s injectors. Knowing about these latent dangers in the fuel at the diesel pump, can you really go on feeding it untreated to your truck? We at Parleys Diesel Performance strongly advise against it… and believe a FASS diesel lift pump is an excellent diesel performance upgrade choice. Get the most out of your diesel engine and your fuel dollar with a FASS fuel pump from Parleys Diesel Performance.

Diesel Power Fuel Mileage Tips Continued

December 5, 2008

So the suspense has built up long enough, its time we finally give you the rest of the secret diesel fuel mileage tips  that Diesel Power Magazine ran in their October 2008 issue.  Over the next couple of days we will cover some of our own diesel performance centered fuel mileage increasing methods as well, so be sure to check back for them. Let’s get on with the tips to increase your diesel fuel mileage!

23.  Don’t Keep Tank Full: Remember that diesel fuel weighs about 7 pounds per gallon.  Vehicles have a tendency to nickel and dime their owners to get some revenge make every pound count.  Remember the straw that broke the camel’s back.

24.  Remove Front Drive shaft: This easy modification drops the vehicle’s weight.  It also makes for one less moving part on vehicles without lockouts.  When winter comes or if fuel prices drop, put it back on.

25.  Locking Hubs: Disconnecting the wheel from the axle with lockouts will improve .4 mpg.

26.  Live on the edge and ditch the spare: This option will come more real once run-flat tires become an option for consumers.  Still, tires today are so good the spare rarely gets used.  We would guess that 3 times out of 10, the vehicle’s spare tire doesn’t have air in it anyway.  In its place, have a few plugs and an old-fashioned hand pump.  Craftsman came out with a 19.2 volt hand-held air pump that inflates low-volume tires up to 200 psi.  As for plus, the ones from Napa are much better than the cheap ones.  there is a big difference.

27.  Look to racing: Now is the perfect time to upgrade to fiberglass fenders.  Why stop there when you can spring for a carbon fiber hood?  With fuel at the prices they are, one can’t afford not to.

28.  Lexan:  Replace as much glass as possible, although be sure to leave the windshield alone.  Imagine what would happen in every pickup and SUV would replace just one piece of glass with this welterweight material.

29:  Aerodynamic Tricks: Air dams and tire skirts push air away from un-aerodynamic areas.  Early Broncos and many other cars from the ’50’s and ’60’s used tire skirts.  With everyone’s attention focused on fuel consumption, we might see this retro styling return.

30. Manual Trans Swap: When shopping for a used truck, avoid three and four-speed automatic transmissions and seek out five and six-speed manuals, so your engine can stay in its torque peak.

31.  Radiator Relocation: The mud bogging crowd has done this trick.  With the radiator by the tailgate, the front could be totally blocked off.

32.  Diesel Reinforcements: Propane, compressed natural gas (CNG), and hydrogen are alternatives in supplementing diesel.

33.  Remove all traces of the air conditioner: This will make it cleaner under the hood and crate less load on your engine.  Many serpentine belt systems can be routed with the compressor removed; all that is needed is a shorter belt.

34.  Lower the truck: If you want big tires, get out the saw and cut the sheet metal.  Don’t lift your truck anymore than you have to.

35.  Fuel Connoisseur: Don’t fill up when the tankers are filling the tanks.  Let the fuel settle before putting it in your truck.

Alright, now I am just going to come out and say that the bulk of these tips are just flat-out retarded, if you are so concerned about increasing your diesel fuel mileage that you are willing to remove your A/C and cut your sheet metal instead of lifting your truck you should be driving a ’95 civic and definitely not a diesel.  Have any input? we would love to hear it.

Diesel Performance – Miracle or Snake Oil

March 6, 2008

There are so many products out there that just seem to be too good to be true and there are too many people out there that are more than willing to take advantage of another’s lack of knowledge.  There are also sooo many out there that are willing to play on peoples emotions; you know, the whole “You can have amazing results for practically nothing, and for only minutes a day at no cost to you”.  We’ve all heard it before.  So what makes diesel performance parts, like a chip, or a cold air intake, or an exhaust any different.  You might ask yourself, “Can adding something that small to my vehicle produce as great results as so many people tell me they do?”  Or will these items really pay for themselves in the form of increased diesel fuel mileage, and reduced wear and tear on my vehicle?  It is these questions about these products that I am going to address and at the same time educate, because knowledge is power my friends.

If you were to modify a gas engine for performance, you would be required to install a different camshaft, bore out the cylinders to increase displacement, install high compression pistons and heads, increase fuel intake capability by installing a larger carburetor or injection system, adding a turbo charger or supercharger, adding a chip, and enlarging the exhaust system.  But then you are still restricted by emission control systems.  On the other hand, diesel trucks and cars are mostly turbo charged, and they already run at a higher compression ratio.  Whereas on the gas vehicles you would have to make those changes.  If you were to make those changes to a gas engine you would truly have a ground pounding beast, but would lose every day driveability.  The diesels on the other hand, are nice to drive around even with considerable modification.  With a cold air intake, a diesel chip, more efficient injectors, and a more open exhaust system, the diesels are still a nice ride, but when you really give it the gas, all heck breaks loose.  There is enormous power without reducing driveability.

Because of the nature of diesel engines, they are designed from the factory to withstand much higher compression ratios than a gas engine.  The diesel fuel combusts when it is compressed to a certain point whether or not there is optimum air. By simply shooting more fuel into the combustion chamber you can make more power. When you then improve the air ratio & timing of the fuel — you can make dramatic power and also improve engine efficiency.  Gasoline requires a spark to ignite it & must have the appropriate mixture of air to burn properly.  Also, there is also a lot more energy in a given amount of diesel fuel than in an equal amount of gasoline.

Below is a break down of the most popular modifications and explanation of their benefits.

1. A cold air intake is sealed away from the hot engine air, and is located where it can take in more air.  Cold air intakes are equipped with a filter that can take in up to 300% more air.  Cold air takes up less space, so there can be even more air, all that air helps to burn all the fuel providing more power and better fuel economy.

2. Diesel chips make alterations to how the fuel is delivered to the engine, making it more efficient and more powerful.

3. A bigger exhaust or a mandrel bent exhaust (keeps the tube round, and the size constant) improves exhaust flow. Getting exhaust away from the engine is just as important in combustion as getting air into the engine. There are exhausts now that will even vacuum exhaust away from the engine, making it so that the engine doesn’t have to do that work.

All of these modifications add to the fuel economy of the diesel engine, over time they will actually pay for themselves in gas savings, and will continue to keep your money in your pocket for years after they are paid for. Diesels are the wave of the future and more and more economy vehicles are being produced in diesel versions because they are capable of so much better economy. – Nathan Young
