Ok so I think I've got an air leak. My engine won't tune and there are bubble in the fuel line. But my tank is good. All of the lines are good to. Is it the carb then. I'm having this same problem with both of my .15 4 tecs
A bad exhaust o-ring, cracked header, bad coupler, or even a broken pipe can all cause fuel pressure problems. How did you check the tank and lines? They can suck air without leaking fuel.
It doesn't leak fuel. I blew in one hole and plugged the other. No Auer leaked. I think it could be the exhaust. I bought a new rubber pipe.
I'll check in a bit
Tip the car over with fuel in the tank. If the o ring on the tank Is good then it shouldn't leak at all. That caused me so much issues.
