Upgrading Your Diesel Fuel System: A Simple Guide

Diesel engines are still very much around, and not just in the trucking industry. Those who wish to boost power without sacrificing efficiency (as diesel engines rate number one for the most efficient internal combustion) usually fit a diesel engine into their vehicles — and if they want a little extra oomph, they’ll upgrade the diesel fuel system.

The Basics

Before you go digging around in your engine (or pay someone to dig around in your engine), it’s important to know the components involved in diesel fuel systems. Your engine will contain a diesel filtration system, complete with diesel fuel filters to ensure that no dirt or debris gets into that very expensive engine, an injection system, which is responsible for injecting the fuel that will be turned into mechanical energy, but — most importantly — your engine will contain a diesel lift pump.

The fuel lift pump transfers fuel from your tank to the injection system. Virtually every diesel has a lift pump of some kind, yet many people prefer to purchase and install aftermarket pumps to boost their power past factory settings.

Feel The Power

Modifying the amount of fuel that gets injected, either through programming (if your truck is computer-equipped) or manually, is one of the easiest ways to push your engine and “see what she can do”, so to speak. Unfortunately, most factory diesel lift pumps cannot keep up with the change: when supply fuel pressure drops, the injection pressure into the engine will also drop, and so will horsepower. In fact, running pressure that’s too low can potentially harm the injection pump and cause it to fail, so any time you modify your engine for more power and performance, you’re going to want to install a new lift pump as well.

Now that you understand how your system works, you can begin looking for a suitable lift pump. Low-pressure fuel pumps are inexpensive (carrying a price tag of around $100), but they almost always fail in diesel setups. It’s a much better idea to do your research and find a quality diesel lift pump that has been proven to succeed.

High Roller: Unbelievable Diesel Built LBZ Suburban

Human ambition and imagination have long achieved the most amazing and unbelievable feats. While souped-up, massive car builds aren’t usually the first things that come to mind when discussing profound human achievements, they are nonetheless still on the list. We have no doubt that you’d only have one thing to say when St. Louis native John Eilermann pulls up in his decked-out behemoth, fittingly named “High Roller”: check out the build on that one.

Eilermann had a few basic needs that transformed his 1972 Chevrolet Suburban into the monster it is today:

  1. He wanted a vehicle that was large enough to fit five to six people
  2. It needed to be able to handle his 300-acre property, off-road style

Originally, Eilermann was dead-set on building a Jeep or a safari vehicle to meet these needs — that is until he saw their price tags. Legitimate safari vehicles can run up to $150,000, so the wheels were set in motion to produce the luxurious and powerful High Roller.

Powered by a 6.6-liter LBZ Duramax diesel engine, this car has got it all: limo style seating, moonroof, and no backglass to truly give it that safari-style feel. Known affectionately as a “Duraburb”, High Roller rides on 2007 GM 11.5 AAM rear end with a Yukon Grizzly locker, and a 1989 Ford king-pin Dana 60 front end with a Trac-loc limited slip. Matched perfectly with the wheels and tires, High Roller uses a six-inch Rough Country lift kit, Bilstein rear shocks with remote reservoirs, and a 4:56 gear ratio. Although massive, its 550 horsepower and 1,050 lb-ft of torque give it all the power it needs.

Diesel engines are as powerful as they are efficient: boasting an average if 45 MPG highway rating, Eilermann will be able to have his fun without breaking the bank on gas. If you find yourself in the mood to create something as exciting and unique as High Roller, finding the best fuel lift pumps, diesel fuel filters, and diesel filtration systems are a good way to get started. FASS fuel pumps are known to be reliable and clean, and there are undoubtedly a number of FASS fuel system dealers near your location. Take a page from Eilermann’s book: start with a simple idea and take it to the professionals — your FASS fuel system dealers — to perfect.

Diesel 101: Everything You Need To Know As The Owner Of A Diesel Engine

Knowledge is power, so if you drive a big rig or a truck that runs on diesel, it can’t hurt to know a little bit more about it. First of all, there are multiple kinds: just as gasoline is rated by octane, diesel is rated by its cetane, which indicates how easily it ignites and how quickly it burns. Logically, higher ratings equal higher efficiency.

There are two grades of standard diesel fuel (sometimes called diesel oil): Diesel #1 and Diesel #2. You don’t need to worry about differentiating their cetane levels, however, because all diesel automakers specify Diesel #2 for normal driving conditions — Diesel #1 is usually only used by truckers who need to carry heavy loads over long distances.

Diesel fuel is also measured by its viscosity; like all oils, it gets thicker and cloudier at lower temperatures, and can even become a gel and refuse to flow under extreme conditions. Diesel #1 is more efficient in cold temperatures because it naturally flows more easily. But don’t worry if you live in a place that experiences exceptionally cold and bitter winters: most service stations offer blended diesel fuel for local weather conditions.

Historically, diesel engines have been around since the 1890s. However, it wasn’t until a few decades ago that conventional diesel exhaust was linked to cancer due to exposure and considered extremely dangerous. As a result, clean diesel engines were created: with many diesel filtration systems and diesel fuel lift pumps in existence designed to reduce harmful emissions, use of diesel fuel has become considerably safer — just be sure not to inhale the fuels themselves when filling up.

Today, there are over 50 different types of diesel engines to choose from. You have the pick of the litter when it comes to your particular set up: the FASS fuel pump (fuel air separation system) is remarkable in its ability to combine both a fuel lift pump and filtration system to increase efficiency, which increases mileage. FASS fuel pumps also boost engine performance and extend the life of your diesel injection system which saves you money on repairs and replacements in the long run. They are also exceptionally clean, so you don’t have to worry about your carbon footprint or personal health.
