HDPE liner in fuel tanks?

[thudpucker]

On the subject of removeing leaking fuel tanks, how about a Tank made of HDPE or at least a tank Lined with HDPE?

The new Outboard tanks are HDPE. Without an injury, I've never heard of one leaking.
So where in the industry is a tank or liner to fix or replace the ones in our old boats?

Might be impractical to supply drop in tank liners in different shapes and which conform to regulations..

If you need a new tank check these guys out...hundreds of tanks in all shapes supplied to the marine industry.

HDPE is fine, but you have to be able to weld it up, if you want to make a tank. Plastic welding is fairly easy and heat gun/rod kits are available, though you really got to want to do this, particularly when the commercially obtainable polyethylene tanks are reasonable and non-corrosive.
