I've bought a new tank from (royal choppers ,india) to use while I try and remove now softened tank lining thanks to f☆☆☆ing ethanol !! The liner was fitted to deal with a petrol weep at one of the back mounting bolts so that will have to be dealt with again !!! I don't wish to remove the original tanks foam so any suggestions as to sourcing suitable substitute for new tank ?? Thanks,.Roy

Out of interest Roy, which liner was it?
 
I used the pads from AN but still had issues with the tank tunnel rubbing on the frame, so I added foam pipe insulation that worked very well.

I can't remember as it was at least over 12 years ago. It was a two part epoxy product that set a beige pink colour that worked admirally until the ethanol content was increased unknown to me and many others !!! Yet another huge outlay with nobody to blame ??? It's destroying petrol pipes , oil seals and if the content is increased possibly the new (works now) anti ethanol products. Sigh, Roy.

Will look into that. Some of the higher density insulation perhaps ?
 
I used the AN foam when I switched to an interstate tank. It wasn't enough to lift the rear off a frame bracket. I tested what height I needed with a closed foam pad I had for mounting a sat nav on a car dash. About 1.5" thick. Works so well it's still on there, held on by zip ties.

I was surprised it needed that much extra thickness.
 
I used 1/4 “ closed cell neoprene and cut to suit. It has been this way since 2011 with no issues.

Surprising! Did you have the thin pad in front and the thick pad in the back? Where did it rub? Was it an original tank?
 
I can recommend the Caswell Epoxy very highly. Preparation is everything - I use an outfit that performs a tank dip and strip that leaves the gas tank without any liner or rust whatsoever and a light protective coating. I use clay to protect the threads and prefer a 70degreeF day to apply the two-can mix. Treats a tank up to 10 gallons.
 
I can also recommend Flowliner, it’s a two pack solution as well.

Flowliner Armour Coat - 100% Ethanol proof petrol tank liner

Give your tank 100% protection from the ethanol in modern fuels. Suitable for all metal, plastic & fibreglass tanks.

For the fuel tank pads, I go to a shoe shop and buy the cheapest pair of flip-flops they have and cut them up to suite. I also used it under my oil tank and battery.

I have mentioned before that I fit the padding to the top of the frame tube. Much more accessible for inspection/additions/removal/replacement.
 
Just to echo Rob above I zip tie the foam pieces to the main frame tubing - the zip ties are the reusable type so readjustment is very easy.

I may get it going once again. I am going to use (frost tank strip) on the original, with great care ! The paint on it is almost perfect so steady hands requ'd. As for stopping the weep, that's in the future. Thanks to all as always, Roy.
