    Hi

    My fibreglass 5 1/2 gallon tank is finally losing the battle with ethanol. Interested in anyone with a metal interstate tank for sale as I've yet to hear anything good about the Indian ones.
    Thanks

    Thanks. I could never find a thread with links to an Indian interstate tank anyone had had food experiences with. Will have another look and also look at the link above. Thanks again.

    That ebay seller is based in the UK but buys all his items from India, that hopefully means he has the knowledge to select the right items and inspects them, he is mentioned on the NOC site and the side panels he supplied were ok quality. As he himself is Indian that should also be a plus as he will be aware of the issues.

    that is the ebay guy that I bought my interstate tank from. It's worked good enough for me. It doesn't have the interior baffles inside the tank to keep the fuel from sloshing around like the original tank. Obviously, it's not painted so you have the task or the expense of painting it. The only other thing I would mention is that it had some antirust coating on the inside which I tried to remove with various chemicals. After not having all that much success removing it all, I finished the tank, installed it, and fueled it up. I removed the filters on the petcocks and put clear filters inline on my fuel lines so I can see if there's any of the coating flaking off and entering the fuel stream. No issues so far after an entire year of use.

    rsvintage2014 sold me a good tank for a very good price. I'm really glad I have a larger tank because I don't put ethanol fuel in my commando and the larger tank makes it easier to avoid putting corn squeezin's in my fuel tank by increasing my range before I need to fuel up again.

    Quick update. I bought the tank from the UK supplier referred to above. Arrived yesterday. Have only had a very brief look but looks ok so far. Needs some grinding work where the tap threads have been welded in but I'm guessing the paint shop can do that. Will post some photos.

    Will report back after closer inspection.
    Those that have also bought this tank- do the standard norton petrol caps fit, do you know?

    I found the filler neck on my interstate tank to be a tiny bit lower than the stock filler neck on my roadster tank. The "heel" of the petrol cap was very close to scraping the tank when I opened the cap. I think I touched the "heel" of the cap to the grinding wheel to radius the back edge of the cap to make sure it didn't scratch the paint. ALSO, the hole for the roll pin to mount the cap was sloppy, so the cap wobbled. I carefully enlarged the hole to mount the cap to the next roll pin size, and drilled out the cap hole to that same size... I would suggest that you do all this fitting before you have any paint work done.

    I also fitted the cheapo italian BAP petcocks like you see on the left in this picture... which do not leak a drop and are working perfectly so far.... They were $10.75 each versus the $29. each for the ones on the right. both from oldbritts

    Thanks. Much appreciated.

    So, to be clear: apart from the pin and shaving the cap slightly,you were able to fit one of the traditional style norton filler caps to these Indian tanks? That sounds like a result.
    I will compare the dimensions of mine tonight with my original fibreglass one. I will also get some taps fitted and see if the tank holds fuel before I get it painted!

    Thanks again

    yes. fit the taps and the filler cap first, then take them back off and hand the tank off to your painter. I do my own paint work. Make sure your painter uses a highly fuel resistant top coat especially if you use ethanol fuel. The combination of petroleum and alcohol based fuel really requires high tech paint chemistry...

    good luck with your tank. I hope it works out as well as mine did.

    Quick update.
    Pleased with it so far. It's a little smaller than my 5 1/2 gallon fibreglass one. But when on the bike everything still looks in proportion. All the threads for taps and mounts seem ok. And like you, I note that the pin hole for the cap seems a bit bigger so I will drill the cap.
    I've filled it up and will leave it overnight to check leaks.
    I would upload photos but I'm not sure how to on this forum?
    Thanks again for the input.

    Sorry. One last question I've just thought of. Anyone know the right thickness of pinstripe? Mine is a 1972 750 combat so I believe single stripe. All input appreciated. Hanks

    Single stripe for 750' s, will measure a stripe later on.

    .1875" on a new paint job, but .15" on an older factory job but hand done and wavy to say the least. Both look correct at 3 ft distance.
