[QUOTE=Fulcrum525;3306530]Could be. I have underbody panels which thus far have kept everything clean underneath the car. I'll have to wait for warmer weather to check these though.
I'm pretty sure my fuel hoses only clamp on. And yes I have a fuel heater (Ironically I never really noticed the little bugger until today while searching for the source of this leak
)
I've thought about rebuilding the lift pump on both my SDL and the Gwagen. Again its something that i'm waiting for warmer weather to work on.[/QUOTE
I was not sure.
If your Hose uses a Calmp simply change the Hose. On mine it sucked a slight bit of Air only when the under the Hood temp was hot. I found that the Hose was so hard and inelastic that even though the Clampwas tight apparently when it was hot under the Hood it sort of was bending the Plastic on the the nipples of the Plastic Primary Fuel Filter and allowing Air in.
For about $3 for a foot of Generic Fuel Hose I solved the problem.
