I fixed my second fuel like leak last night, this was the one in the return line, the other leak was that evap line.
I pulled the canister as well to see if there was any gas in it, and there was some, enough to hear is sloshing around when I shook it. I’m guessing that little bit is normal?
I’ve noticed that the truck acts up at about the same place while going to work, almost every morning, and seems to be a little further down the road on colder mornings, so it’s something to do with the engine temp triggering something. It happens after almost 5 minutes of driving.I’ve noticed that the truck smokes when it acting up, it looks like blue or black, but it’s hard to tell with the sun shinning from behind me, and while I’m trying to drive in busy traffic haha
Since the evap vents into the intake, is there anyway it could be venting gas in, causing it to run rich like it does? Or feels to at least.
And I also looked at one of my spark plugs last night, they’re not that old, but they’re not AC Delco’s, so I’m still going to swap them out at some point haha.

I never replaced the egr valve, I just removed and cleaned it, and made sure there wasn’t carbon build-up causing it to stick, and made sure it opened and closed easily and smoothly.
I might “fix” the cat this week sometime, but I might wait until I replace my muffler first. It’s not leaking, but the baffles inside are loose and rattling, and I’m thinking one might be out of place, restricting flow. I don’t figure that’s the case, but I need a muffler anyway, the rattle drives me crazy, and it makes the truck sound like a tractor haha
But with that evap line going to the tank from the canister, aren’t those more for fumes? I had what seemed like a complete line full ( or more) of gas run out while I fixed the leak in the line, and it was still running out until I got the clamp tightened.

This one is electric.

I thought about that, but don’t they normally turn on the engine light when they stick? My ’97 chev tripped the light when the valve stuck open just a hair, wasn’t even open enough to make the truck run bad.

So I still haven’t figured this out yet. When it acts up, it feels just like the truck is running rich and floods out. It acts exactly the same as a carbed engine running with the choke on.
I did find some fuel leaks tho, not in the feed line, but in the return line, and that smaller line from the evap canister.
I don’t figure that’s my problem, but I did notice that the evap line was completely full of gas. I didn’t think that those lines had much for gas in them, maybe I’m wrong tho.
Still no engine light, and I still have the clogged cat issue. When you shove it to the floor, it doesn’t have any power at high rpms, and doesn’t accelerate.So I still haven’t figured this out yet.

What’s the problems you’re having? think it’s not pumping gas at all? or just pumping to slow to keep the motor running?
If you think it’s not pumping at all, I’d just pull the line off the carb, and stick it in a bottle, then run the motor off gas poured in the carb and see if any gas pumps into the bottle.
The pressure for a carbed engine is pretty low, so if you get a fuel gauge hooked to it, I believe it’d only read a couple pounds pressure.What’s the problems you’re having? think it’s not pumping gas at all? or just pumping to slow to keep the motor running?
