Petcock for fuel line

Post by JLT » Tue Oct 05, 2021 9:46 am

Years and years ago, I had a 1971 bus that had a fuel line petcock between the tank and the fuel filter. I found it very handy when changing out the fuel filter, since I could shut off the gas. I also used it when I needed to park the bus and leave it unattended, like at an airport parking lot.

I sold that bus, petcock and all, back in 1994. When I got my present bus, I was reminded of how convenient it was, and have developed a strong hankering to install one on the bus. Can anybody recommend a source for such a thing? It would have to have the proper nozzle sizes (7 mm, I think).

Original carbureted VWs use 5mm ID hose.

Any concern about a new failure point?

Well, there is that. But the petcock on my old bus never showed any evidence of leakage. And the clamps were always checked every time I replaced the fuel line, which was every five years. They never showed any signs of failure, either.
