Vacuum Pump & Gas Leak

[jim wagner]

Thanks guys for the info on the vac. pump location.

You said that you had a gas leak at carb. fitting. If this is at the gas
line to the carb. fitting and the flare isn't cracked try using a Parker
copper flare gasket they work great. Cinnabar sell them. P.N. 2GF-5 for
5/16 tube and P. N. 2GF-6 for 3/8.

Jim,

Thanks for that idea. I'll try it.

At this point, I have to take the carburetor off to get the
fuel line fitting into the inlet fitting. I've had to tighten it so
tightly that the steel line itself is starting to twist. I think
what's happening now is that with vibration, etc. the
opposite twist in the line is just working to loosen the
fitting after a while, and it will just never tighten up
properly. The whole thing has to be redone.

I think if I figure out a way to reroute the fuel line and use
the shorter inlet fitting, I can make it work. May the Lord
richly bless GM for designing the fuel line to enter the
carburetor with a 90-degree bend a fraction of an inch
from the thermostat housing. Yes, richly bless . . .

Thanks again!

Don't forget to leave the filter out of here so you will never have to come
this way again.... Someone said there was a fitting made to self-thread
into this place and replace this fitting!!!

Toby,

I used a 3/8" x 20" brake line from Car Quest to bend up the line for my
Holley conversion. I bought a Rigid tubing bender from Home Depot and used
the original for a guide. Requires patience, but not too tough a job.

Thanks Patrick for that idea. Sounds like with a new line
and the shorter inlet fitting, with the copper flare gasket I
might get this under control . . . . (?)
