Tank sealer for fibreglass Hornet tank

[Gordonh]

Hello all, hope everyone is well, can anyone recommend a tank sealant for my fibreglass Hornet tank, is there any grade of petrol available that can be used without the tank being sealed.Thankyou Gordon.

I've used Flowliner now on 3 tanks and I'm more than happy with it. Obviously rust shouldn't be too much of an issue for you, but preparation is the key to a satisfactory result, so make sure the inside of the tank is thoroughly clean and dry before lining it.. Regarding fuel that wouldn't attack the tank material, I'm not really too sure.. HTH

Hi, if your Hornet used sparingly perhaps Aspen has petrol in cans available also in the UK (if that is your location)Expensive of course. Should be without the detrimental ethanol.

Hi - maybe not the answer you want and by all means try for yourself, but having sealed 2 Commando fibreglass tanks and the one on my current Spitfire without success, I gave up. Just last week I bit the bullet and ordered a new steel tank from India. I have seen one from this supplier and it is great so I am hoping I have no trouble. The big problem with fibreglass tanks is getting the sealer to adhere to its surface no matter how much preparation you give it. Hence you will see very few sealers that are recommended for them. The other issue is that as far as I know these tanks were banned, because of splitting in a crash and it is a grey area as to them being legal to use now. As far as petrol is concerned if you Google Esso petrol it will tell you that their premium high octane petrol has no ethanol in it despite it saying E5 on the pumps. The trouble again is if you go down that route without any liner in the tank, just the petrol fumes will find any porous bits (common problem) and will bubble through. I tried 105 octane from Classic Fuel Solutions (expensive)and although the bike went like the cl;appers, the tank still suffered. My new 4 gallon tank cost me £265 post free so your smaller one may be less. Sorry to be so negative but I can only tell you my experiances.
Regards
John.

its a known problem nowadays with ethanol, I had a RE Cotinental to work on , the suggestion from RE was to try a new modern Indian Conti metal tank,  but fittings were different. Ive sealed tanks in the past for rust but ethanol has started peeling and blocking fuel supply, apparently modern sealers are ethanol proof but only time will tell. Ive tried Por 15 , Petseal and another but??

Hi,

I think that there is a specialist tank liner in Cawston, Norfolk.  I do not have a name but I know someone who has used them.

I think it is this one.

I will let you all know how I get on with this tank from India. The tank from this supplier I have seen was purchased by a friend and fellow Club member for his immaculate Spitfire. He said he had no fitting problems with it. I will give out the details of the supplier when I am satisfied with it.

Regards
John.

Caswell tank liner will work fine but it is all in the prep.
If you get a strand of fibreglass not covered it will act as a siphon for the fuel.
