Fuel leak

'95 can smell it and can see the fuel when it rains just can't find the leak.
I cleaned up the valley area,with the truck running I can't see any drips or spray anywhere. Do you have to remove the filter housing to see if it's leaking, or should I be able to see the leak without disasembly?

Thanks, DD

It could be the weep hole in the Pump, Its on the bottom side of the pump and hard to see. leaks are pesky to find sometimes. Check the Hoses too, They get cracks in them over time.

Hoses looked good got a good eyeball on them. If it's the weep hole does that mean new pump time?

Thanks

Most fuel leaks will resullt in fuel puddling in the valley. Depending on where in the valley wil give us a better idea as to what to check. If you can only smell it w/ no visual evidence, then check the fuel rail plugs located at the rear of the heads. The plugs are o-ringed and will sometimes develope a leak (or so I've read). If the leak seams to be abiguously on the rear of the engine, then I bet it's the plugs. If it's in the valley, then it will most likely be a very visible drip from the starter or nearby area.


An afterthought... When you say that you can see it when it rains, do you mean that you can see a sheen on the ground? That could be oil, fuel, trans fluid, or something left be the previous vehicle.
