fuel leak on rebild
 

hey guys just about done putting my new engine it my 93 rx7 efini, all i ahd left was the itnakes and radiator when all of a sudden i hear a dripping and smell of gas, i looked underneith to find gas dropping quite constantly from the right mount all the way up from the fuel rail area but its to hard to see now that the engines in.
anyone have an idea of what it could be?

You said it yourself, the leak is coming from the fuel rail area. If you reused old hoses, they're likely to leak. If the UIM is off, it's just a matter of looking hard enough to spot.

Only way to tell is get under there and make sure all the clamps are tight, check all the hose to make sure there aren't any cracks and check your FPD.

If you put it back together you should be double checking your work.

CHECK THE FUEL DAMPERS! After my experiences, that would be my first guess. Don't know how similar the 3rd gen is to my 88 10ae in that area, but those are what gave me a problem and a sprung a bad fuel leak.

You prob need to replace the crush washer on the fuel rail. Give Ray Crowe a call. It's not exactly cheap but he should be able to get you what you need.
