Can we add a fuel tank drain plug?

[White One]

just noticed that our plastic tanks dont have a factory drain plug fitted. This is not normally a problem unless you put the wrong fuel in or a contaminated batch of fuel goes in.

does anyone know if its at all possible to add a drain plug somehow ( plastic welding maybe ) or the best procedure to deal with this scenario? would a siphon system in through the filler neck or from the fuel filter be the best way?

Most tanks don’t have drain plugs nowadays, it’s normally easy to just drop tank out to clean properly

Maybe ask someone like ARB about it? They have Frontier polymer long range tanks and may offer some advice. Or try some of the metal fuel tank makers like The Long Ranger, or Brown Davis; although they make metal tanks, they may have some advice

normally that would be doable , but say you had just filled up with 60L and some was contaminated , you would like to know that you can get it all out , and dropping a near full tank would be quite heavy.

In a workshop you just use a gearbox jack. Then tip it all out, wash dry and refill.
Thing is you won’t know it’s contaminated when filling, it’s later on and then all your fuel lines will need cleaning out.
Best way to really clean it all out is removing the tank. Drain plugs would be a weak spot for fuel leakage too,
Guess you could do it but cost versus doing it may not be worth it

thats when you jam a hose pipe down the filler neck and siphon it all out.
