Fuel Tank Leak

[dchelette]

Fuel tank has a small split. It's seeping fuel making a mess. The tank is polyethylene I think. Any ideas on how to patch it? Was thinking of wood burning iron to try and melt it and seal the split. All ideas welcome.

Thanks

3m makes a product called panel bonding adhesive , that should work fairly well on dodges fuel tanks , assuming ;

you remove all traces of diesel with laquer thinner ,

seal the split as best as you can , either with a plastic welder , or like you where thinking a wood burning iron / soldering iron .

grind the plastic with a 36 grit disk ,

wipe it down with thinner again
then apply a layer of panel bonding adhesive 6 to 8 inches away from each edge of the hole .
it takes sevel hours to set up , 24 hours to cure , but that can be cut way down with gentle use of a heat gun .

You should have posted 2 days ago. Mark Nixon just went to Dallas with a load of parts, he could have delivered you a tank.
Maybe send him a PM anyways, he has lots of parts.

Depending on where it's split, I wouldn't trust a repaired tank. 20 something gallons of fuel hitting the road can be dangerous for somebody, and expensive for you.

Thanks for the info. The more i study it the more i think i will replace it instead of repairing.
