Well got the beast turning and now I’m running into a fuel starvation problem. The dam thing is running really lean. Here’s what I’ve got:
87 Jeep YJ Wrangler, 360 V8, R4B intake, 291C heads ported, Crane 272 cam, stock fuel pump & re-used the stock stainless fuel lines running from the tank.
At idle its running just a little on rich side. As I give it gas on acceleration it drops down to ideal. When I really hit it, the A/F gauge goes completely in the red and sometimes totally disappears. This also happens when I’m in 4th & cruising. Further it starts to heat up really quickly due to the lean situation.
My question is which of the following is the culprit:
1- fuel pump cant feed the motor?
2- stock fuel lines too small in diameter?
3- carb floats are out of whack?
If anybody has run into this situation before it would be great to get some feedback. Would be nice to have some insight from you guys here before I start tearing fuel lines out & installing electric pumps.
Thanks a bunch
