Replace gas tank because of top seal leak ?

[GreggT]

Anyone heard of this?

Apparently that seal up top is attached to the tank (not the neck).....wish I had a parts page to better visualize.

When the tank is full I have a slow gas leak.

Of course that tank staddles the center subframe /differential......so much of the front end has to come a part..

It's looking like labor probably will be as much as parts......bummer.

I was just looking into a fuel cell conversion but that would be around $6K.

This is a fluke......is it not?

Can you tell what seal they are talking about?

[GreggT]

Thanks for the illustration....it helps.

And yep.....I'm still trying to understand the diognosis so far....will be talking with them again today.

OK....the best guess is that it's a malfunctioning seal is located where the neck inserts into the tank......and unfortunately, that seal is apparently inside the tank.......worse yet, it is 'part of' the tank. The assumption is that the neck inserts to this internal seal.

The rings illustrated as 16 & 17 are not seals.......17 is actully a soft foam, 16 is basically a metal washer.

None of this can be accessed from up top.....you can barely reach in and with a couple fingers touch the foam ring.

Expensive.
