Vapor Lock

Gearhead999 · 05-12-2001, 05:08 PM

Hey Fostang,

Remember the wives tale cure for vapor lock??

Putting those pinch to open wooden clothes pins on the fuel line [metal line] between the pump and carb. When I was younger we use to see it all the time on flathead Fords and other flathead engines. They tend to run alittle on the HOT side.

Well I had a 1954 Packard come in my shop last month. The older gentlemen who owned it passed on and his daughter brought it in to get it in running order. It had a flathead inline eight. Well when I pulled up the hood I couldn't believe my eyes. There, in the year 2001, were around 6 or so wooden clothes pins on the fuel line. I started to laugh and my mechanics, all under 40, couldn't figure out what they were there for.

One more on the old Packard. I sent the fuel tank out for cleaning. When the runner came and picked the tank up he asked me what kind of car it came out of. When I said "Packard", he said yeah but who made it. Is is a Ford, Chev, etc.???

Best way I know to fix is insulate and install an electric pump back by the tank so it will push through it.
