Fuel tank sealer issues.
Hi All,
I made my fuel tank myself several years ago, and used some tank sealer that I got from Frosts in order to give my a bit more confidence that it would
not leak.
Recently I have been getting fuel starvation problems with the car, and decided to have a look at the filters. These were ok however when I removed
the hoses I found the pipes to be full of the tank sealer flakes. The outlets for the tank drop down from the top of the tank into a little swirl pot
at the bottom.
I am guessing that most of the sealer material is now flaking off and floating around at the bottom of the tank. Do you think that I should get a new
tank made in aluminium or somehow try and clean it out and re-coat the tank. (Tank currently mild steel).
Cheers
Stuart

To avoid it happening again I can't see that using more sealant would help unless you could get all the old stuff off and use a different
kind?
I would have a new ally tank made and forget about it.

I sealed mine by painting it a coat fibreglass resin.

Any recommendations for someone to build a custom Ali tank?

In my experience once the sealant starts to break up the tank is doomed, you will just be cleaning filters going forward,at worst it will work its way
forward and screw up something else.
Time for replacement

He will make one to your design or size. He makes them for MAC1 and MK I believe. He made mine baffled with a sump and 10mm plates on the top for fuel
pump and sender.
The baffles are more like 3 compartments with tubes feeding the centre section so that whenever you are cornering fuel gets sent to the centre section
and into the sump.

Windle sidecars are in Mansfield, make a cardboard template of it, post them it and they will make it for you.
Ive seen their sidecars tanks, and they are very neat.

This is an age old problem WW2 era jerry cans were famouse for it there is a simple work around that was used in the 1970s when UK car
manufacturers experienced the problem with paint flakes inside the tank. They introduce a screen filter inside the tank on the end of the fuel
pick-up pipe. The filter was in effect self-cleaning because it gets washed by fuel.
When clear your existing lines and filters remember to disconnect the fuel pipes and blow the lines back against the direction of flow.

I have heard that the higher ethanol content of the current fuels can attack polyester based fibreglass resins.
