fuel leaking
OK, here's a new one for you guys ,hope you can help me out. my 91 vette in my garage when I came home after a 2 day trip,there was gas all over the floor,about 3-4 gallons leaking from somewhere in front of the engine. Took it to the Cherolet service dept and they stated it probably is a cold start injector and they would have to remove the manifold, has anybody heard of this and what was the fix, all the regular injectors are just 8000 miles I looked in the corvette manual I have and I dont see a cold start injector are they trying to scam me.
please help

No cold start injector (9th) on your car. If there was and it was leaking... it would fill the plenum, run down the runners into the cylinders and leak around the the pistons into the oil pan. Now fill up the oil pan and leak out the oil dip stick....S**T load of fuel in there to get 2-3 gallons on the floor.
1) Check fuel filter fittings.
2) There are two (2) hoses (at least on my 85) that are bent into a "U" shape attached to the fuel line and return (metal lines on each side). These are located on passanger side toward front of the block between the fuel filter and front of the block. These have been known to leak. If so it would siphon fuel from the tank.
I WOULD NOT RUN THE CAR AT ALL UNTIL YOU FIGURE OUT WHERE THE LEAK IS AND FIX IT.

thanks for your suggestions, went back to dealer, they found that the fuel pressure regulator was leaking and the fuel was coming out the trottle body down the air intake and leaking out the front. $750 for repair but at least it will be done and warrantied.
