Has anyone had a problem with the leaky fuel tap as supplied by Moss - 589190?
The 60 year old cork technology is just not working for me. Remedy?

I can't say that I have used the one from Moss. I am using ones from a motorcycle shop. Cost was less than ten dollars and is very unobtrusive. I may be able to locate a company and number if you are interested. Or I even have an original fuel tap sitting on my self if anybody is interested.

The cork has to be adjusted from time to time; I'm guessing the new ones from Moss probably need to be adjusted right out of the box. Loosen the lock nut on top of the handle then use the screwdriver slot to turn the shaft CCW until the cork will just barely move in the bore.

I got tired of having to adjust mine many years ago, and found a piece of nitrile fuel line that fit. Seems like it was 5/16" id, but I honestly don't remember for certain. Anyway, I think I only adjusted it once in 20 years or so. Of course, I don't use the tap very often either. Since my driveway slopes, I can just park the car with the nose up to clean the sediment bowl.

Steve, I'm actually surprised your car has the fuel tap. I thought they were deleted around TS60,000 ?
 
Hey Randall,
The tap was a last minute addition during the motor installation. I liked the idea of having a period fuel shutoff in that location and this seemed like a good idea. This is a actually a replacement for the first one which emptied the tank, in the garage, overnight. I'm lucky there was no heater to spark a renovation!
I was unaware that there was any adjustment! I'll try your advice as mentioned above.
Thanks,
Steve
 
Mine leaked also. I actually got a replacement from MOSS since I found the cork was destroyed. The replacement is marginal, and I have never turned it off anyway. So, if you want a shut off, I would find something else.

Just to be clear...the originals leaked so bad that they do not even dock points in judging if you remove or bypass the fuel shutoff valve.
 
Hey Randall,
I no longer have a potentially explosive garage. I followed your instructions and now the leaking fuel tap problem has been (temporarily) solved.
Thanks.
 
When I got my car, the tap didn't leak. When I shut it off, the leaking started. Replaced the cork, still leaked. That was one of the first items I removed from the car. I thought it was too much of a fire hazard; it was leaking pretty bad. I thought it was a good idea, but a bad design.

Just give it time...it'll leak!
 
Cork comes from the cork tree and that bark is getting rare when you think of all the wine bottles that use cork. There are veins in cork like most living things and the poor cork available today leaks because of the direction and size of these veins.

So I put a threaded plug inside my original S-T "petrol stopcock" and it doesn't leak any more. Then I added an electric solenoid operated switch and shut-off valve in the fuel line under the frame under the driver's seat and I switch off the fuel line with a hidden switch up under the dashboard.
