Gas tank repair

Anyone repair a plastic fuel tank successfully? Some road debris hit the bottom of ours and created a small hole , it's bigger than just a drip. Salvage tanks for Expy El are almost impossible to find and new ones are dealer only and $1300!! I would love to just repair the easily assessable hole on the bottom and be done, but all I read are mixed reviews if it can be done.
  • Stop Dripping
    Rub a bar of bath soap vigorously across the damage
    Drain tank.
    Use tire tube patch cleaner around area
    Scuff roughly with rude 90-grit sandpaper
    Apply fiberglass swatch soaked with expoxy resin
    JB Quick weld works fast and permanent
  • A plastic welder may be able to repair it. Depends a lot on the material. If the tank is ABS, there are various repair methods available that have the ABS solvent and ABS material.
  • A fiberglass repair kit may work. I have used fiberglass for many different plastic repairs.
  • I am not certain about fuel tanks and have no idea what kind of plastic your tank is made out of but for black plastic I used this to mend my black water holding tank and it has held up for years. Plasti-Mend Black... The tank was split just about in half. This stuff welded it back together it has not leaked a drop since.,
