OK, I have been chasing Gremlins (demons, not the cars) in my GM TBI converson on my 2F for about 4 years now - on and off of course. Today I dropped in another TBI unit to see if that would help. The cruiser started and idled just fine - finally! But then my brother noticed that the high pressure line had a leak. We cut the engine and I tightened the hose clamp that had loosened during the TBI install and let the gas evaporate - I was ready to go for a drive! BUT, now that the fuel leak was fixed I had the same lousy/non idle that I've been fighting for so long.
Sooooo, here is the latest ignorant question of the day. There are two fuel fitting on the 4.3 TBI. One has a larger fitting and takes a larger pipe, the other is obviously smaller. I've never had any instructions and have never owned a GM TBI vehicle, so I assumed that the larger line/fitting is the intake and the smaller line is the return. Now I am second guessing that decision. Anyone know for sure???
TIA
