Since this is a fuel injected motor, I decided to use a Tanks, Inc. in-tank fuel pump. The pump is a 255 LPH Walbro unit in their special housing. It is an easy install (on a new tank anyway). It has a tray that acts as a sump to retain fuel when accelerating.
I started by ruining a brand new 69 repro tank. The Tanks, Inc. pump needs 7" to work right and the 65 tank was just a little short. The 69 20 gal. tank is about 1 1/2" taller.
I cut a 4 1/2" hole with a hole saw. (I did this on the ground, not on the sawhorses.)
The pump flange needs a flat surface to mount so I flattened the ribs using an Eastwood flanging tool (it came in handy for something!).
I mounted the pump as far back as I could and on the right side. This should help keep fuel in the tray (sump) during acceleration.
I'm feeding the engine with -8AN stainless hose with a -6AN (3/8" hardline) return. A Summit Racing 100 micron filter will go inline right out of the pump. An Aeromotive A1000 regulator will be mounted under the hood. The fuel system should support 600 HP (got to feed those 39lb injectors!).
It's a little dirty in there, but here's a pic with everything plumbed.
I am going to cover the tank with a 14 ga. steel cover to isolate it from the trunk (to keep fuel out of the trunk in a rear-end collision).
The battery will mount in the trunk and power the fuel pump through a relay controlled by the engine PCM.
