My 93 has the later model blower with 10%, plenum, maf, injectors. Just added a 255 fuel pump. The car runs great just smells like gas but its not leaking any..

Thanks for your help and ideas.

Chart your gas mileage. That will tell you something. I get a fuel system rich CE lamp code after driving. And charting the mileage, 8-12mpg in my case. Way too rich, need some dyno time.

What size injectors are they and what maf are you using?

Where is the smell coming from? It's possible their is a bad seal or hose somewhere on top of the tank that is causing you problems. A small leak there will cause you to get poor milage and likely dry/evaporate before ever reaching the bottom of the tank. Double D mentioned the fuel level sending unit (FLSU) were updating for the 95+ Tbirds to SS units because the early ones rusted out and cracked their welds (or something like that). I'm replacing mine before the shootout as well as all the hoses and what-not associated with the tank because I get a slight fuel odor from the tank area right after a fill-up.

I'd check the tank just to be sure, but if thats not it I'm guessing your injectors/maf combo maybe causing an issue.

In the interior or under the hood. If in the interior and not under the hood, it's likely something to do with leaks at the fuel filter, or the hat seal at the fuel tank, or the cross over hose on the fuel tank, or the filler neck vent hose.

If it's under the hood, could be an injector leaking at the rail or in the head from a damaged o-ring or not seated properly.

Most likely Pablo is right, you probably have a small leak at the tank. Of course it won't drip, it just stinks like gas because it's mostly fumes that escape that way.

Just please be careful, my SC smelled like gas and it turned out to be a slightly nicked injector O-ring that caused fuel to leak on the intake manifold when the engine was on and it happened after I put my 42# injectors in, I'm thankful that nothing bad happened!!! (and no I didn't drive it like that) LOL

Did you replace the injector O-rings when you swapped in the used injectors? If reused, they are very likely to leak.

Also, the seal around the fuel pump can leak and eat away the connector on top of the tank. That could become a burning issue ... so to speak. :rolleyes:

It was at wot, and I found the problem it was the rubber ring around the the fuel unit, didnt know there was one on each side. No gas leak just fumes.

Thanks guys.
