thinking ahead about fuel supply

[jiggityjoe87]

hey everybody I'm in the middle of piecing together a fuel system for my 70' suburban 2wd 1/2 ton and I've been reading everybody's posts about getting an 87-91 tbi blazer/suburban fuel tank and adding a tpi pump. Well I'm going to try and make it work in my suburban so I went to the junkyard today. lo and behold they had a 90 suburban 3/4 ton 4x4. so I started taking the tank down after about 45 minutes i had the tank on the ground only to realize that the junkyard punched holes in the tank . After all the struggle I figured I couldn't come home empty handed so I took the sending unit/internal pump and now I'm in search of the specific capacity fuel tank it came from. I took the dimensions of the tank before i left. The tank is 35in long X 28 in wide X 12 in tall. Lastly when it comes to the TPI fuel pump I've read a lot of people saying get an 85' fuel pump, but then I think to myself the only tpi engine that year was a 305. Are all TPI pumps the same? because 87' was the first year of the 350 TPI. I just don't want to go through all this work just to put in a pump that can't support the engine.
