Re: Vaporizing gas fix

I asked the question about vapor lock in the Phoenix area to my local Packard club and I got 4 replies:

1. Electric fuel pump back by the gas tank.
2. Add a gallon of Diesel fuel per tank.
3. Replace the metal fuel line from the fuel pump to the carburetor with a thick rubber fuel hose (it resists heat build up).
4. Put clothes pins on the metal fuel line from the fuel pump to the carburetor. Of course this was an old school fix, but these are old school cars.

I guess any one of these would work. Currently I am using the diesel method and it's working. I might try the rubber fuel line next, that way I don't have to look for diesel fuel.

My first vapor lock was because I had my left front tire wheel nut too tight (the one holding the drum on). The wheel bearing got hot, the heat traveled up the spindle and heated up the fuel line and the brake line (which melted my stoplight switch) but that's a different story. After loosening the wheel nut that problem was solved. I was too new to know how tight or loose the front wheel should be but after 40,000 miles I think I got it right.
Now this problem of vapor locking now has been bothering me for 3 years. I hope I have it licked!
Good luck with yours.
