I have an 83 Scrambler that my father converted to a 350 years back. I have recently decided to get it back on the road; needs transmission, brake lines done, body work, and the fuel pump must be taken care of.
Fuel pump burns out because (I think) it doesn't have enough juice, being externally mounted, to supply ample fuel to the thirsty V8. I want to get a tank with a pump inside, or utilize any suggestion one of you out there may have specifically regarding this problem.
How much psi is putting out? If its a carburetor it only needs 4-6psi. And I'd stick with external inline pump. Makes it much easier to replace and maintain. Not to mention they are usually cheaper in ny opinion.
I'm running a Walbro high pressure in-line pump combined with a cheap Holly low pressure pump. Generally last me 8-9 years. First one lasted about 8 years, and I'm still running on the second one for almost 10 years (knock-on-wood). Make sure you keep the high pressure pump primed... starving them for fuel will destroy them pretty quickly. The a low pressure pump near the tank serves to prime the high pressure pump in the engine compartment.
It's TBI, and noise is not TOO much of an issue as it is after all a Jeep with a 350!
External: Any suggestions on a good pump that WON'T burn out?
Internal (Directed at dg6772): Which assembly did you use?
Thanks all for the prompt response!
I used the assembly from a 1990 1/2 ton truck. I took the pickup,return tubes and pump brackets, then put all that on my CJ sending unit along with the electrical. Sounds much worse than it actually was.
