Fuel System Upgrades 

I am planning to convert this car over to fuel injection. From the research I have done, the best way to do this is to prep your car to be as close to a modern fuel injected car to begin with. You do not see modern cars with unbaffled fuel tanks, external fuel pumps or external fuel pressure regulators for good reason.

I chose to replace my fuel tank with one from Tanks Inc. The Tanks Inc tank has several advantages. 1) It is slightly deeper allowing more room for an in-tank pump to be installed. 2) It has internal baffling so the fuel pump does not become uncovered when fuel is low. 3) It has a relief on the top so you can run the lines, vent tubes and wiring without hitting your trunk floor. 4) Being deeper, also means it has 4 more gallons of fuel capacity. 5) It is powder coated. Outside of cost, really no downside.

I went with the 255l/ph Walbro in-tank pump module sold by Tanks Inc. I believe Holley and Aeromotive modules will work as well but all would meet the needs for my application. Relative to the Tanks Inc module, it is not exactly a bolt in plug and play deal. You need to take measurements of your tank and cut the intake and return line lengths accordingly. Nothing tragic but I pretty much expected it to be ready to run out of the box.

I chose to regulate and filter using the Vette/LS regulator which is preset at 58 psi giving me a "returnless" fuel system. I figured if it works for my C6 Z06, It would work just fine for this application while reducing the need for and cost of a separate filter, separate regulator and all of the fittings in between. I picked up one from Speedway motors with the AN fittings brazed on eliminating the need for adapters.

For plumbing, I used 3/8" Earls Vapor Guard hose from the tank to the regulator and back, then a 3/8" copper/nickel metal line from the regulator to the front of the car. I used two AN to tubing adapters from Russel on the metal line then protected it with some stainless rock guard for it's entire length.

For venting, I ended up venting the tank to my Firebird's original factory EEC system which is basically a standpipe (fuel separator) mounted above the fuel tank that in turn vents to a stock charcoal canister.

Total Cost: $650
