Hey guys got around to replacing the pet cock on my ’95 trx300fw. Bought one off eBay. Got the old one off and re-installed the new one. The outlet on the new petcock is much smaller than than the original. So I read on here y’all were using 1/4in fuel line. Although 5/16in works but still leaks even with hose clamps. Well I just happened to have some 1/4in fuel line from a outboard project. It fits the petcock but it won’t fit the inlet to the carb. So I guess my question is what is the correct fuel line size? Why do these after market petcocks have a smaller outlets? I was thinking I have the wrong petcock, but all the ones I’m finding have the same outlet.
