Raptor petcock

[leggman1]

Just looking on ebay and saw raptor petcocks going for less than ten bucks. They are 34mm between the screw holes. Will this fit my xs1100 tank. I have removed the octy and the double outlets on the stock petcocks make it hard to get a clamp on the back outlet fitting. This would be a cheap fix if they are the same.
Thanks Dave

I think I found the answer. the xs petcocks are 46mm not 36mm so it won't work.
