Gas leak - what caused this?

[hpaulb]

These cracks are common on our tanks. Do a search for many threads on this. Saw a good one in 06 with pictures and a procedure. Mine does the same when near full. Just havn't done anything about it yet. Wife wines alot about it.

I have the same damn problem, I just live with it.

If the fumes are from the front driver side, it is the charcoal canister.

If it is coming from the engine bay, check your fuel lines, this should be obvious.

If it is from the rear it is the filler neck or the rear fuel lines. Mine is from the rear, pulling the rear carpet revealed nothing, likely it is the filler neck...PITA, not worth fixing to me.

hay thanks Hoss..It is coming from the rear (gas smell) but as of yet, can,t see anything wet near the tank,,

No problem. I can't find any wetness in my situation either. I suspect it is the filler neck in my car, and have tried full fills vs 8-10 gallon fills. The lesser fills results in fumes still(especially if the car sits for a few days), but they dissapear much quicker than full fills.

"Topping off" on cross-country drives left me with fumes for about 20-30 miles at speed. Becuase of this I suspect a filler neck problem in my car, you may wish to try a similar situation as well. Nevertheless, I have fumes if I store the car with anything around 10 gallons for a couple days, with the windows sealed.

I have not noticed a significant difference in mileage on 400 after 400 after 400 mile 1 day trips or highway/commute 10 day fillups...so, I don't suspect a serious(if any) leak.

Hopefully that information and some testing and looking around will help you figure out your situation.

When I fill up my tank , I have a strong gas odor until it drops below the half way mark.. I,m thinking the seam is leaking, Any thoughts on this??

When this happened in my car, it turned out that gas was leaking into where the fuel level sender is. As soon as you would go around a corner (if the tank was full enough) it would spill into that and make a big pool of gas. Probably pretty dangerous.
