got a 94 that is leakin from behind the fuel filter. we have put 2 new filters and sensors on it along with all the washers and o rings. does anybody have clue where it could be leakin from

 

Could be your starter contacts. I would also check all your connections especially your grounds.

 

i had the same problem it was the battery ground, connector was broke and loosnd up! try grounding one of the batterys to the fender and see if it starts
