Fuel Leak

[Brody133]

My dad's truck, I believe it's the early 99, but anyways, it's leakin' fuel. At first I thought it might have been the fuel cap so I replaced it and it stopped for maybe a week and now it's doin' it again, maybe even worse. It's leakin' like right behind the fuel cap somewhere and drippin' down in between the heads on top of the block. I'm not really sure what it could be? Help would be great.

Probably the fuel bowl drain valve(That thing with the yellow handle on it), it has 2 o-rings back under it that leak. Mine was and I thought it was the cap like you. Took mine off to replace rings, couldnt find any so I put it back on with old rings and it hasnt leaked a drop since.I got lucky

I appreciate the input Mikey, thanks. Yeah, I'll check that tomorrow and hope that's it and hopefully I won't have to get new o-rings, but just tighten everything back up.
