Well, Im not sure how much help it is, but here it is. I took it facing towards the cab with the camera over the rear diff. Your fuel tank should have two wires going to it. One should be light blue and black, and the other should be white. The white one is your ground and the other is your fuel gauge sender. I'm not sure where the ground was supposed to attatch originally, but I found mine wedged between the frame and a bed support. I soldered on an eye connector, shrink tubed it and put a self-tapping screw into the crossmember. Not much to it really. Probably took 10 or 15 minutes is all.

 

Alright. I shall look for that at a later time, this week is kinda full for me at the moment. I really appreciate the picture though, gives me a little better idea of what I'm looking for.


I disconnected the vacuum advance and took it for a drive. It's beastly. I wonder if it's been running lean for some reason.....

 

maybe the vacuum advance mechanism is bad? have you tried applying vacuum to it with the distributor cap off?

 

Not yet, I did pop the cap off, IDK what the hell I'm looking at down here.

I have been doing some reading on it, some folks are saying manifold vacuum is better then the ported that this truck has....hmmmm.....

 

with the cap off when you apply vacuum the pickup should move. i think ported vacuum should be better. if things are working properly the ported vacuum port should have no vacuum until you start giving it some gas so it seems pretty strange that you are having problems at idle with the vacuum advance hooked up.

 

I might try that today before I leave (again).
Yeah, I understand the concept, I'm wondering if there is a leak in the hose. It tries to backfire when you burp the gas real heavy.
Disconnect and plug the vacuum advance and it growls, snaps, and roars like an angry lion.

 

^Oh yeah, I tried the vacuum trick, didn't work or I didn't suck hard enough. lol




Anybody know how big the factory trans cooler is? The one on the truck is massive.

 

so the the pickup didn't move at all when you applied vacuum to it or did it seem like there was a vacuum leak? almost sounds like something might be stuck but if something was stuck, unplugging the vacuum advance should not make much difference.

 

I couldn't see anything moving or hear anything.


It wouldn't make a difference unless it was stuck "open."

 

but if it is not moving you are getting no vacuum advance so the timing would stay the same. if this is the case it is strange that the engine performs better when you have the vacuum advance unplugged.
