4108 gas tank

[dhoadley]

I had suspected I had a gas leak, but after getting a new cap/gauge it was confirmed. I thought it was probably the rubber grommet, so I tore apart the dash (finding a huge mouse condo!) to find that the tank had a crack at the seam that the PO had already attempted to seal. Is there an effective way to repair a plastic tank, or do I just have to bite the bullet and buy a new one? Thanx, Dave

Steve WI has luck with Seal-All to a similar tank I believe. I think he layered it on.

Found "Seal-All" at Advanced Auto, and it works great. Thin, like Super Glue. I found a small hole at the seam about halfway up. Put a dot on the hole and put a small piece of duct tape over it. Let it dry for 24 hours and then coated the tape and seam with a second layer brushed on with a small disposable brush. Reinstalled and filled to the top and ... No Leak! Thanx Bob.

I myself did not have much luck with the seal all...it still leaked!

I did a plastic tank off of a green tractor for a friend. I cleaned the tank with laquer thinner and compressed air, roughed it up with sandpaper, cleaned it again, and then applied seal-all, a thin layer, then duct tape, then seal all, then duct tape, till I had a good patch. I let it dry for a full day and then put the tank back in the tractor. It has been over two years and still working.

I spoke too soon when I posted "No Leak dOd". It leaks still, just much more slowly. Look for my post in the "Parts Wanted" for a replacement gas tank, part #1687038SM. Thanx, Dave
