Fuel Shut Off Valve
Installed a new (repo) fuel shut off valve on my '31 last spring (inside cab..not late '31 style). I'm making some new fuel lines from the sediment bowl to the carb and noticed that gas is still filling up the bowl even though the valve is shut off. I emptied the bowl on Sunday and this morning it was almost full again.
Do these reproduction valves not last long? |

Re: Fuel Shut Off Valve
I've only used original valves lapped with toothpaste and had good luck.
Did you add the small filter screen to the valve? Every car should have one. |

Re: Fuel Shut Off Valve
All of the aftermarket shut off valves that I have ever used leaked or didn't completely shut off the fuel to the carburetor, after a while. I'm using a used original on my roadster and it does cut off the gas to the carbs but will have gas residue on the cut off handle if it sits over time.

FWIW: Just one (1) experience: 1. I had the same shut-off valve leaking experience here after (2) years, after: a) Replacing an old leaking original shutoff valve with a new after market shutoff valve; &, b) Witnessing hard particles of rust (ferric oxide), mixed with hard sand, (either already in my tank, or inherited from dirty gas station gas at my last refueling), creating uneven wear on the soft brass shutoff valve mating surfaces; &, c) All coupled with having "no" gas tank screen, part no. A9195-T in my tank. 2. Hard steel rust & hard sand in a gas tank can mar any soft brass on either new or aftermarket shut off valves. 3. The recommendation for a gas tank screen (A 9195-T) in Snyder's catalog, (where they indicate their shutoff valves), is not just an ad to get customers to buy gas tank screens -- their honest & most sound caring advice comes from years of experience in trying their best to advise customers that rust & debris in fuel tanks is what causes leaking shut off valves -- in order to reassure this advice, please call Mr. Snyder, & ask him. 4. After unsuccessfully trying to lap an original 80 year old shut off valve a few years back, I called Master Model A Mechanic "Rainmaker Ron", (Mr. Ron Cloat, then owner of Standard Auto Parts), about his advice on lapping original shut off valves with different lapping materials. 5. His response was that he had collected about 40 original shut off valves over the years at swap meets. He later spent 3-4 days trying to lap old valves whereby he said he was successful with only 3 out of 40 when he submerged them under water & tested them under air pressure all of which was a lot of wasted time. 6. I quit lapping mine, forgot about the repair kit & ordered a new shutoff valve. 7. Many shutoff valves have minor leaks, the carburetor shut off valve leaks & the gas evaporates before it hits the floor in liquid form -- wives with sensitive noses that never smoked cigarettes can always smell it in a garage -- most men don't. LOL 8. I admire your high degree of intelligence & concern about careless fires caused by dripping gas in a garage -- remember it is your Model A, your garage, & your house to do what you want when you want. Hope this one (1) experience helps. |

Re: Fuel Shut Off Valve
I put a 1/4" Parker valve (Tee Handle) on my gas line, under the hood. When I garage the car I use both the inside valve and under the hood valve. It I'm out playing I will use just the inside valve depending on the drive, heat etc...

Re: Fuel Shut Off Valve
I'm now having problems with a new valve that was installed last Summer. The valve worked perfectly and then last week started becoming very difficult to turn on/off. I tried spraying with WD-40 and PB Blaster but it didn't seem to help at all. Any suggestions short of removing it completely and rebuilding/replacing? Besides the simple fact that it's a PITA I'm worried that it may create a leak if it has to keep going in an coming out.

Re: Fuel Shut Off Valve
Muttley,
Jist take yo' old valve to the Hardware Purveyor & they have a petcock type valve, that fits perfectly, for about $4.99 (CHEEP!) Them old valves are about as sophisticated as an old barrel bung valve! (DRIP, DRIP, DRIP!) Why mess with UN-SUCCESS? Bill W. & Dog

Re: Fuel Shut Off Valve
This is what I use. They are very reliable. Now as I stated this is on the fuel line after the filter and before the Carb.
