Gel seeping from fuel hose connection

Post by paul1149 »

In a recent thread I got help with my fuel line problem. The quick connector had come loose from the hose between the pump and the filter.

I replaced the hose and fittings, and all seemed well. It's been several weeks now.

But while under the car for something else, I noticed that the quick connector at the filter end was not dry. On touching it, it felt just a bit slimy, like a thin petroleum jelly. It was not gasoline.

I wiped it dry, but a couple of days later it was wet again. This has been going on for over a week.

I contacted the seller of the hose, and he says "It is rust inhibitor on the fuel line which has no effect on the quality of the product and does not affect the use."

I'm not clear on why rubber hose would have rust inhibitor on it. Does anyone have any insight on this? I've been soaking a short piece of the hose and a connector in gasoline to see what it does, but it's only been a couple of days at this point.

I'm attaching a couple of pics. Much appreciated.

If it smells like gasoline, it is a fuel leak.

It doesn't smell like gasoline, and it's more viscous than gasoline.

Good point. It always started right up. The other day it took two tries to get running. And then when I got home it idled roughly. Maybe this is the cause.

Wow, I just checked my jar soaking the hose and connector in gasoline. It's been two days. The hose seems to feel fine, but the connector definitely is beginning to slime up. I didn't expect that. Definitely a problem. This means it's happening up at the pump end too.

Did you ever figure this out? When gas is exposed to the air and allowed to evaporate, it creates a "gum" (carburetors get gummed up, etc.) which is what I think is happening here.

No, never figured it out. Decided not to worry about it. Car seems to be running fairly well. Thanks.
