Fuel System - 95' Impala Gas tank and pump
Note the height of the lines and sender.
The fuel tank is from a 95' Impala, it is plastic and is 2 or 3 gallon bigger that the stock 71 Chevelle tank. It already has internal baffles for EFI requirements and to keep the pump from staving.
I am using a Racetronix B-Body (GM Full Size) Pump Kit that includes a Walbro 255lph pump and there wiring kit that is heavy gage wire and relays that connects to the Alternator to ensure full voltage.
In order to mount the tank I had to modify the frame rails by removing about 1/4" from each side frame. I also had to build up the Chevelle's floor pan rail where the tank seats on.
I made a access panel to service the pump if needed and also due to the fact the the tanks area around the fuel lines are about 2-3" higher than the rest of the tank and if I didn't cut the floor pan, the tank would have had to sit another 2-3" lower.
I used some 1x1/8" metal to create the longer tank straps
Here is the tank mounted
The Tank does sit lower that the stock Chevelle in the rear area but should not be too much of a problem (just watch the speed bumps !)
Frame area that needed some triming on both sides
I was able to use the Chevelle mounting bolts for the Straps
