fuel issues

ok so here is what i got iv got a 1992 yj and i put a 4.0 out of a 2000 cherokee in it and the problem is my original 4 banger had a return fuel line and this 4.0 has no return fuel line so i put a brass t in the supply line and a piece of hose to a needle vavle hooked back to the return line then i turn the fuel pump on to build pressure and once the pressure builds up you can here the fuel pump bog down i then open the needle valve to let some of the pressure return to the tank and it runs fine like this but i done killed three fuel pumps in 4 months luckly the warranty covered them i looked at the fuel pump for a 2000 cherokee and my 1992 fuel pump is way different so i guess what i have to do is get a gas tank for a 2000 jeep and the fuel pump so has any body this problem before thnxs for any input

After my swap I just capped the return line. Then installed an inline pump, and installed a vented gas cap.

Works just fine for me, runs like a champ.

have u changed the fuel pressure regulator bc that might be putting to much pressure on the pump not allowing it to flow correctly

Later years use 48psi, older 4.0 about 38. So change regulator to a chrysler mid-late minivan.
