Fuel pump filter replacement
I noticed a leak from my fuel pump filter canister that's part the fuel pump. Ethanol had gummed up and ruined the o ring. I unscrewed the canister off to make the exchange, fuel poured out of the pump and continued until I made the exchange. It lost quite a bit of gas and would have drained the fuel tank. I changed the fuel years back and I don't remember it being this messy a job. Logically fuel is gravity fed from tank to pump but I don't remember it being this messy a job when last done. Sorry for the stupid question!

48/52 has a 7HC-9189 petcock shutoff at the base of the tank.
The pictured pump looks to be for a 55/56 and there doesn't appear to be a listing for group 9189 for those years. One can certainly add a generic brass fuel shut off valve.

It sounds like you "got lucky" and created a siphon when you dropped the filter canister this time, just like sucking on a garden hose. A simple vice grip clamping the rubber connector hose from the hard line to the pump would have stopped the flow. Something to remember next time.

All the previous post are right on, I have a shutoff valve I installed the filters I buy from NAPA there is a small o ring and the filter has a nipple ring. I put the filter on the inlet then install the cap. That pushes the filter in place. I also use fuel lube. On all the o rings. This corn fuel additive they put in fuel these days will attack the orings the fuel lube will kinda protect the orings. And delay that decay. Just my opinion. I also cost the top of the filter can. To get a good seal.AJ
