I have a new e-body gas tank here that is back from the Overhaulin' days that I would like to put to use.

A 5.7L Hemi is going into my car [with the potential for "light boost" down the road] as well as some autocross and/or road course time. I would like to get away from a external surge tank and keep my fuel control within the "stock" gas tank.


For starters, I am looking to pickup a TanksInc fuel pump module with a Walbro 400lp/h pump [$295, they claim up to 900hp, for the extra $60 I'll take the flow potential]. I would also be buying the TanksInc recess mount [10"x7"x2"] to give me some room between the trunk floor and the top of the tank.

I have an Autometer fuel gauge that has never read right with the stock sending unit. The gauge also oscillates with the sloshing of the fuel, which is annoying. To combat that problem and work with internal baffling, a vertical "no slosh" style sending unit would be used.

So I did some very rough dimensioning of the stock tank and guesstimating the other parts to throw together a visual of what I'd like to setup. With the 10"x7" hole in the tank I have a nice amount of room to stick some baffling and an internal surge tank. The box around the fuel pickup shown is 10x8x6 [~2gal]. The 1.5x1.5 squares in the bottom would be filled with flat hinges to help control the direction of the fuel.

My out-of-pocket for this setup would be approx $450 and it should support pretty decent power. I have -6 alum line from the tank to the engine compartment that I would be using already, along with a GM filter/regulator assembly.



Thoughts?
