Ok, so I just reinstalled my professionally cleaned injectors in my 88 TII, put everything back together.

She started up after the fuel system was pressurized again. Ran good for about 30 seconds then it started missing so I shut her down. Look under the car and theres a big puddle of GAS!

Took the upper intake manifold off, and I couldn't find a leak around the injectors anywhere. Then i noticed fuel around the vac line that goes to the brake booster. Took the hose off and gas came out!

Any ideas anyone???

 

Bump??

 

whoa wtf?

 

Fuel went up the brake booster line? WTF????

 

I know on the S4 N/A cars, the lower intake manifold has a vaccuum line attached to it that goes to the brake booster. Check that area out. Its on the back of the LIM between the intake and firewall. Should be a steer tube with a banjo bolt attaching it to the LIM.

 

Well, either you filled your intake manifold up with gas and it found it's way into the brake booster line, or you ran the booster line to the fuel rail by accident.

 

The steer tube should be facing upwards. Did you check the injectors to see if they are staying open? I know you just got them "Professionally Cleaned" but just in case... Did you remove the vaccum line at all before??? Maybe you installed the line where the fuel return goes? I got no ******* idea yet of what to think... Take us step by step on what you did.

 

Haha guys, figured it out, it's my additional injector setup that injects right before the throttlebody, over time it's built up fuel in a few vacuum lines I guess and when removing my intake it cause a leak in the vac line so it was leaking fuel(I'm guessing this was my main leak, but i replaced all stock clamps and now she's not leaking a bit)...
