You may think about upgrading your carburetor or converting to elec­tronic fuel injection, but most people don’t give much thought to the rest of the fuel system. As you push the per­formance boundaries of your Chevelle, you eventually reach a point where you must upgrade the entire fuel system. The fuel system is made up of the fuel tank, fuel line from the tank to the engine, fuel filter, and fuel pump.

Richie is running a 75 chevelle fuel tank in his mercury with the sender out of my old beretta and a 12 psi tbi pump going to a standard external regulator, he said the beretta sender popped right in. My mom had that with her LG4 - made me hate mechanical pumps forever, had to install the electric. We install a Holley EFI-ready fuel tank with in-tank fuel pump in our 1964 Chevelle. How to Install an EFI-Ready Fuel. Tank and inline electric fuel pump.

Each of these components has its limitations, and all of the stock com­ponents were designed with some pretty limited performance expecta­tions in mind. At best, the original big-block cars had larger steel fuel lines to deliver a higher volume of fuel. With the other upgrades you’re making to your car, you need to man­age the force created by turning cor­ners at speed, improved braking, and possibly accommodate fuel injec­tion. This chapter covers everything in the fuel system leading up to the carburetor or fuel injection system. This Tech Tip is From the Full Book ““.

An original or replacement tank works fine in all but extreme performance applications. Once you reach certain speeds, or in certain types of racing, a fuel cell is required for safety in a crash.

This is especially critical with fuel injec­tion, because you don’t have the float bowls of a carburetor to act as a reserve. Any time the pickup tube isn’t covered with fuel, you suck air through the fuel system and feel a momentary loss of power.

The simple way to mount a fuel cell is to bolt it to the inside of the trunk floor and vent it to the outside. The drawbacks are a loss of trunk space and the need to open the trunk lid every time you refuel. The alter­native isn’t a whole lot better, which consists of cutting a hole in the floor and recessing the fuel cell through the floor. This lowers the fuel cell for better center of gravity, but doesn’t remove the drawbacks. This also requires custom fabrication to attach the fuel cell to the frame rails. If you use a factory or replace­ment fuel tank, you want to inspect, and in most cases, change the pickup tube and fuel-sending unit assem­bly.

The six-cylinder and many of the V-8 cars came with 5/16-inch fuel lines, which are too restrictive for a modern V-8. You can purchase a stock-replacement assembly with a 3/8-inch pickup tube and new fuel-sending unit for the fuel gauge. A 3/8-inch fuel line is roughly equivalent to a -8 AN line, and is capa­ble of supplying the volume of fuel needed to feed up to approximately 600 hp.

Once you’re above that level, you need to consider a fuel cell with -10 or -12 outlets, internal fuel con­trol, and the whole nine yards. Fuel Line The type and size of fuel line you use from the tank to the front of the car is very important. Race cars use braided hose because it is quick and relatively easy to plumb. The con­nections thread together, and leaks are very rare. It is essentially a rubber hose with braided steel around the outside to protect it from abrasion and to increase the burst-strength rating. Some hoses have additional layers, such as a Teflon insert or higher-strength exterior wrap.
