Hi guys! Ive done the carbureted 4.3 swap on my 93 but am experiencing some issues with the new frame mount fuel pump. the new pump is pulling thru the original in-tank pump and after about 45 minutes of running the pump stops sending fuel. I have tried several things now...exchanging pump (was still under warranty)...have set up a line to a jerry can behind the pump to by-pass the in-tank pump...check if its getting power when pumps stops working but i can't figure this out.
Has anyone run into this?

Why not run the original in-tank pump regulated down to carb pressure? Are you sure you're not vapor locked?

i just changed from push pump mounted on frame near the tank to a vein pump mounted on the fire wall and seems to have solved the issue! :-)
