fuel tank
i am rebuild a 81' complete remake, while replacing the fuel tank. there is a difference in tanks. My tank I pulled out has T in the tank off set by 3" from sending unit assemble, it is inline to the fume canister as well into the fuel tank. (???)can this be used as a return line
Iam replacing the motor and trans to a 383 stroker with TPI multi port fuel injection system and a Monster 700r4 trans, keeping the Dana 44.

I put a TPI setup on my '72 years ago, the main feed line is hooked to the fuel pump almost directly under the tank, the filter is between the tank feed and the pump....the pump is hooked to the stock 3/8 steel fuel line going forward.....I not sure how the later sharks are set up with the return lines, but my old '72 has a stock 5/16" return line to top/right of the tank, and works fine with TPI....... the evap emissions float valve is on the top left of the tank and of course feeds the canister under the left fender liner under the booster/master cyl.....Sorry I can't help with any T 's in the newer tanks....I suspect it's not as bad as imagined....

SO...you still connect a hose from this LEFT SIDE VAPOR line to your sending unit where the 3" section of hose was originally attached.
Your fuel return line is on the RIGHT side of the car along with your FUEL SUPPLY line....and they both attach to your sending unit as you know.
IF you are planning on using a 1982 fuel sending unit so you can install an electric fuel pump to it. Keep in mind that this fuel system will be under a lot of pressure...so ...hopefully you have thought out what type of hose to use so you have no problems in the future.

and fabricating a reservoir and attaching it to the sending unit so the fuel pump does not get starved for fuel when it is going through turns....so the fuel pump pick up always has a source to draw fuel from. If the fuel tank stays always has a lot of fuel in it...this may not need to be done...but if a person likes to run on vapors and get the tank near empty...them this reservoir is needed....in my opinion...and is what GM did in the 1984-1996 fuel tanks.
