petcock

Hi. Need Help. Just bought a new petcock from z 1, gravity fed. Problem is, the outlet on the petcock is a 1/4 inch and the original was 5/16. I'm trying to find a way to join the two hoses together. I have 5/16 and 1/4 inch line. I was told the 5/16 wouldnt work with this petcock even with a clamp because it would leak. I was also told I cant use 1/4 inch line on the carborator because it would be too tight. Trying to get on the road for spring. Any help would be appreciated. Thanks Mike

They are right about mixing the hose and fitting sizes, the 1/4 hose on a 5/16 fitting will tend to split and the 5/16 hose on a 1/4 fitting will leak. Many hardware and auto parts stores sell a hose coupling with 1/4 on one side and 5/16 on the other.

Did you call Z1 and bitch at them?

You can also stretch the 1/4" line over a 5/16 fitting by boiling a cup of water in the microwave and soaking the fuel line in it for a few seconds, than stretch it over the 5/16 fitting. This has worked well for me in the past however, once it's on, if you want it off again, you're going to have to cut it off.

Should be two connections a 5/16s for fuel & 1/4 for the vacuum hose connection Other wise you ordered wrong petcock

I agree. It's the wrong petcock.
You need a 5/16 flow from petcock to fuel T.
