Help! Engine swap, no fuel regulator, bursting lines

[Tj1st]

So I purchased a 1986 Jeep Comanche with a 96 4.0 swapped in. I have met an impass with a fuel issue. The 96 engine has a return less fuel system. The regulator and relief valves are in the tank on a 96 Cherokee. On an 89 Comanche (donor fuel pump/sending unit) there was no pressure relief or regulator. So as it sits there is no fuel pressure regulation going on, which has caused 3 different leak occurances. Has anyone ran into this? I’m going to Home Depot to get a brass pressure relief valve, going to try and set it to about 45 psi and t valve it into the fuel delivery line see what that does. Any help is greatly appreciated, I wanna get this thing on the road!

You can probably grab the fuel rail for a '91-95 XJ, maybe a YJ, or ZJ, with 4.0 at a yard and run a return line back as well.

This is probably the easiest option.  Question I have is did they cap the return fitting at the tank or leave it open?
