i had CS tank.....several seam leaks from the beginning metal thin one of front mounting holes only threaded half way shape is like loaf of bread a waste of money got emgo tank have had no problems since
 
Old Britts says they chase the threads for the fuel taps and pressure test before shipping, so I guess both are a good idea.

surprise, surprise -- received my new emgo tank yesterday. don't know much about the company "emgo", but for some reason, I was thinking these things were UK made, however on the box, says made in Taiwan (not a problem, as long as the quality's there). overall, close inspection is good - no apparent issues, but before I do anything, going to check threaded holes and install mounting hardware for a dry fit to the frame - then on to a pressure test before any paint prep.

Can you post a few photos of it?

here you go....

overall, for a pattern part, first impressions, not bad. main issue, the edges are quite rough and need attention to break the sharp edges, and to smooth the form. should be easy enough to do. like any new steel, prep is important. most likely, first coat will be an epoxy primer (sealer)

My painter had to smooth that roughness on the front edge and also the top of the tank between the filler cap and rear. I'd leave the crossbar on there until after pressure testing just as a precaution.

gottcha - probably fab a couple additional straps just for good measure - don't plan on pressurizing the thing much over a couple psi - two, three max. first things first - install all the mounting hardware and fit to the frame - don't want any surprises.

No need to pressurise at all.

Sealing up the holes, submerging it in your bath and checking for bubbles is all you need to do - holding it under the water will pressurise the air inside enough for it to want to escape if there are any pinholes.

The Emgo tanks are properly pressed from decent gauge material using heavy tooling - on the basis they are distributed by Andover and sold by Old Britts, cNw, RGM etc... you should be safe!

thanks - on the feedback here on the emgo tanks, really not expecting issues.
 
The original post asks about tanks from India. I just bought one. If your bike is valued at $10,000 USD plus you should buy the EMGO as stated by the previous posters. If you are not particular and the bike is a daily rider the India tank is OK. I think most of the people on this forum would not be satisfied with the India tank. Just choke and pay the extra money.

What are the problems with the tank you got from India? What makes it better or worse than the one from Emgo?
 
Worth noting that the EMGO tanks are actually heavier gauge steel than the original.
They need a bit of work with filling & priming to even out the seams - it's not just a simple case of slapping on some paint.
The EMGO shape is pretty much exact to OEM - other tanks I've seen aren't. Some are reasonably close, others are just a parody
 
I’m happy with my aluminum tank from India.
the gas cap opens backwards. (Quick way to know it’s from India)
I wouldn’t use anyone’s tank without a sealer.
 
I’ve been using Red Kote tank sealer on all my bikes and aircraft Sense the 70’s, great stuff. Never had a problem. Great for antique carb floats also. My norton tank from India never leaked but with all the vibration I figured why not. Red Kote also works with methanol. I think they’ve been in business sense the late 30’s

The chemical makeup of petrol changes, it changes for the season and also due to other considerations eg the banning of Benzene in the UK and no doubt elsewhere due to cancer concerns. So any sealer that works now may not in the future, you never know how they are going to change the chemistry. So best to rely on an alloy or steel tank with leaks fixed with welding or braze.
 
A sad tale of pressure testing:

I needed to replace the bottom of my MG TF tank, had a friend roll a piece of sheet metal and I tig welded it in. I had it all done with a couple of pin holes to repair. The family was going to some function and someone was holding up the show so I figured I'd make use of the time. Welded up the affected areas, reached down and hooked up the 1 PSI hose to the tank and grabbed the 175 PSi hose instead. You can imagine the rest.
 
You only need a trivial pressure to check for leaks. It was told to me by someone here to place a rubber glove over the filler opening, using some rubber bands to hold it snug, then just blow into one of the petcocks with other closed. Soapy water spray on joints etc will find any leaks. No biggie.

My tank I bought from a fellow member. Supposedly a CommandSpecialites supplied tank which I believe are made in Pakistan. Came up very nice from a local tank painter, who also had his go to guy do the hand pin stripe as to my supplied example photo. Very happy with the result. Bike is not a concourse piece, just a proud rider.

I grabbed my paint sprayer filled with 2/ part epoxy and forgot the in-line regulator. What a mess.
