I've got a Compbrake rear mount RP tank on mine. I took them up my original as a pattern. A few comments which I fed back to them to improve things:
1) They made the tank to the outer dimensions of the original but including the protruding lip. This means that it's actually a bit too big in the body. I managed to get mine mounted OK but had to sit it a bit lower.
2) The powder coat they used for the outside is affected by fuel - it takes the shine off the finish. This was a bit silly considering they were making a fuel tank.
3) I asked them to replicate the small sump on the bottom of the original. They did this but then didn't route the fuel pickup pipe into it which rendered it pretty pointless.
4) I asked them to supply it with the correct outlet fitting but they didn't so I had to procure an adaptor.
5) They just tech screwed the sender on rather than fitting a threaded ring as per the original.
On the positive side, it's fuel tight, was the correct length and they got the angle of the filler neck spot on.
