Re: Fuel Pump Leaking

OK - Here is the latest installment of the Fuel Pump Mystery. Following Howard's advise, I went over the Fuel Filter Bowl and tubing down to the pump. Could not find any trace of a leak. Also, the tubing from the Filter Assembly to the pump enters below the rim of the pump so gas would have to hop up to get on the rim/ledge.

I did pull the dipstick for the sniff test for gas and it was at best, inconclusive. Modern gas simply doesn't smell like the gas back in the 50s that I remember. However, the oil on the dipstick didn't smell quite right either when I opened a fresh bottle of oil to compare. It may be my imagination but it did seem to have a slight gas smell. I must add that I have trouble smelling modern gasoline. The oil still felts "slippery" but it will be changed before the car is next started.

That leaves the pump. I now think Howard nailed it with the gas leaking out the air vent and down to the ledge. I'm hoping that the gas in the oil smell is my imagination as I've got a great engine and the thought that I may have damaged it makes me sick.

The next step, I guess, is to remove the pump and open it up to check the diaphragm for holes.

I'm attaching another picture of my Fuel Pump for reference of anyone else with similar trouble.

Thanks again to Howard, O_D, Ross, DuaneG, Riki and bobp.
