Started smelling fuel at the end of my last ride 2 days ago, but thought it was brother in law who had just filled his mower before I returned home. My fuel sensor strip decided to take a dive on the same trip. (Reading zero) Bought the bike with 64K miles, currently at 98K with no previous indication of fuel leak (that I noticed) during that time.
Today, I opened up the bodywork to try the lighter/spark hack on the fuel strip and there was some seeping of gas around the quick connector. Disconnected the connector, replaced the o-ring with same size Viton o-ring, re-assembled and it was leak free. Ran bike a few minuets. Shut it off, came out a couple hours later, no leak, turn on key and started bike and it was seeping fuel again. Wiped fuel leakage dry and it didn't continue to re-wet.
I'm a bit baffled here.
Is it likely the fuel pump is cracked or more likely the female connector is cracked? Is there a way to diagnose the difference? The male connector appears dry from all I can tell. There is no fuel spraying anywhere, definitely a rather slow leak, however I do have the signs of fuel leaking down the inside of the front left cover caked in some dust/dirt.
The intermittent nature of the leak is a bit baffling.
Does anybody know if the replacement quick connectors are commonly stocked at the "average" dealership? (I know, call tomorrow to be sure)
Thanks for any suggestions.
In the picture you can see a little seeping at the base of the, what I assume is, the reinforcement ring on the pump threads. (Any chance it might be drying/deterioration of the thread sealing agent?) This was after I wiped it with a paper towel. The seepage didn't get any worse, after the wiping, than what you see in the picture, even after the bike had been running several minutes. It almost seems like the leak occurs as it is pressurizing, then once operating pressure is reached it stops leaking. The area behind the connector is wet also, but I can't detect any fuel actually spraying into that area.
