How can the teardrops from the Sweet Potato Petcock outlet be stopped?
This is on a 24/25 coupe. I have to shut off the gas on the sediment bulb to stop the tearing. Or have I answered my own question. I have a new non OE petcock. Most of my rad and oil petcocks have teardrops but I am more concerned with the gas drops.
I've never had any luck with them. Even tried the re-pop "modern style" and they seep, although a bit less.
I have had some luck seating them with toothpaste and then after cleaning that out using Fuel lube. Eventually it will start again especially after some use.
I used valve grind compound and purson(sp) blue No luck.I have a real nice one I can't seem to get to seal.
Thank You All for Your Responses.
I'd think the lapping compound should work. Might be something for the Timesaver stuff to do it a little faster. Make sure the spring is good also.
Many of those types of valves require a lubricating type of soap.
there is some stuff the small air craft guys use on the fuel valves that looks like vasolene but does not wash off with gas. expensive i know, i forget the name.
Here it is, aviation fuel valve lube and sealer:
