Hi guys, 

 

I know there are a few topics on this, but they're all from a good few years ago now, so I just wanted to see what the consensus these days is.

 

I had a peek inside my fuel tank today and noticed a fair bit of surface rust beginning to build up, so I want to get rid of this and seal the tank properly while I can. I've seen a few products on the market aimed specifically at this, but I've heard horror stories all over the place about reactions with fuel, etc. 

 

So what are peoples preferred methods of tank rust removal and sealing? I've seen people mention anything from vinegar to paint stripper, so it would be good to get some different opinions.

 

Cheers

Chris

In the classic motorcycle forums, Caswell epoxy tank liner seems to hold up well to modern ethanol containing fuels.
Surface prep is very important for good adhesion. POR15 does a tank liner kit with several mixtures for preping and etching the metal prior to sealer application.

Ive seen one video showing a poorly done mini tank where the fuel pickup pipe had become clogged. The guy used an old speedo drive cable inner coil attached to a hand drill to pass into pipe and bore it out.

EDIT: here's the video: 

 

Besure you can mask off any pipe work passages within tank prior to any liner product.

For those not convinced to use a liner, one tip is to keep tank topped up while storing car over months to reduce condensation forming on exposed metal. Otherwise, a complete draining and spraying a light oil, WD40 etc within tank to coat exposed metal works ok and does not harm things when refilling later.

Sounds good! How effective is the metal prep that comes with the kit? I'm assuming you have to fill the tank to the brim in order for every area to get a good soaking? Or can you just turn the tank periodically? 

[cooperd70]

Instructions come with it...you have to bring openings so that they don't get coated and turn the tank during the process...think the instructions may be Ava on the Frost web site to download so you can go through the process prior to purchasing it, so you know what's involved.

I've used many of the POR-15 Fuel Tank Repair kits. They work very well, BUT follow the instructions to the letter, if you don't you might be disappointed. It'll take the better part of a day to do the job.

 

Regardless of which way you go, find yourself an old fuel tank sender and seal, cut the sender itself off and then you have that for plugging up that hole. Many kits suggest Tape, which is little more than a pain in the neck.
