So earlier tonight I just got done swapping over a 460 efi to a carb on a 89 4x4. We replaced the high pressure pump on the frame with a little electric pump designed for carbs, put it just after the tank selector.
When I first fired it up, it started instantly, ran for about a minute and we were just adjusting the timing, and it died. pulled the fuel supply from the carb and you could hear slurping sound. so from what I am gathering either
1) the pump we picked up isn't strong enough to pull through the in tank pump ( doubt this)
2) the pickup in the tank has rotten off at a half tank ( doubt this, worked fine before swap)
3) the selector valve is stuck / sh!t housed.
what do you guys think? thanks in advance!
ps - anyone know the color code for the tach, and where in the harness I would find it?
