I'm guessing there is a thread about this out there, but I couldn't locate it (I'm a little impatient, especially when I should be working rather than looking at cool Jeeps). Anyway, here's the story: I have a '79 CJ7 that a prior owner dropped a 360 into. It has the hydromatic transmission and quadratrac transfer case, full time 4-wheel drive. I've been having trouble with vapor lock and I believe this is due to the bigger motor and the fact that the transmission is water cooled, so the temp pushes up just beyond 190, even with the thermostat removed. That said, here are my questions:
I was wondering why my fuel filter has two outlets, one of which goes back to the tank?
Is this necessary or can I plug that line and run a filter that just has one outlet dedicated to the carb?
I don't know that this will change my vapor lock issues, and I'm planning to drop the tank and install an electric fuel pump on the frame rail, with new lines to the motor in hopes of solving that issue, but wondered if the return line to the tank was vital to the operation of the Jeep?
Also, I'm planning to get a pump with a range of 4-7 psi, can this be used as a booster for the mechanical pump, or should I remove it and put a block plate on, or do I need a pressure regulator?
Forgive me for the length of this post, I've been trying to solve the problem without help from all you Jeep gurus out there and now that I have realized the error of my ways the questions have become numerous.
