Hi Vint_mow, would you tell me more about this polyweld? I have tried everything from plastic welding to epoxy pastes and even nail polish. There's a thread I started on here somewhere about the issue. I have never found anything to work. Those tanks were subject to a re-call by Briggs sometime last century because nothing could fix them except replacement. Maybe times have changed now and I am willing to try this polyweld, if you say it works because I have a couple of tanks here that need fixing.

Edit: I found it here. https://www.tapplastics.com/product/repair_products/plastic_adhesives/tap_poly_weld_adhesive/435
However, the only problem is that it requires a flame treatment as part of the process of bonding HDPE and LDPE. That's probably not a good thing for fuel tanks and they add that warning to their video.
