Default Re: Rubber LP generator hose leak

The place where mine was leaking is 'hidden' behind a support strut for the generator.
This makes it very difficult to spray soapy water on the place where the rubber meets the brass.
Much less see the results...
In lieu of a leak detector you might try this:

1) Stop off at your favorite hardware store and pick up a 3/8" flare cap and plug
2) Loosen flare nut on LP hose at the tee and cap off the tee
3) Run a leak down test - if it passes goto step 4 - otherwise you've got a different problem
4) Reconnect the LP hose to the tee
5) Loosen flare nut on LP hose where it meets the generator and plug the hose
6) Run a leak down test - if it fails replace the hose - otherwise the leak is in the generator...

Here is where I bought my new LP hose from:

It's important that the hose I.D. be 3/8" on the low pressure side of the regulator.
