We will do it if for no other reason than to uncover fields of unprofitable endeavors. We love to take them on trips to make list of things that we can fix when we get home. We can't die till all our projects are complete. Thus that's why the average age of owners is near death. May we all enjoy our ADVANCED age. As to the real young owners. You know. The owners under 55. As to those youngsters. May the GMC extend your life with joy. Bob Dunahugh

Dump the mechanical pump and go to two new (lower pressure) pumps:

They're Mr. Gasket pumps for carburetors. Toss the filters that come with the pumps and replace with Wix replacements. Run the relay through a
shutoff (Oil pressure or overturn) and the dash selector switch.

9 psi is courting fire and disaster. Try to maintain 5 psi max in the fuel
lines ahead of the Carburetor inlet. That is about all the inlet needle and
seat float valve can safely and reliably handle.
Keep a cool fuel and it will be less likely to form bubbles, although
with today's formulations, that is like a lifetime of rolling boulders
uphill nonstop. Stay away from off season gasoline, particularly in
California.
The main reason fuel injection has less trouble with vapor lock type
issues is that the fuel system operates under higher pressures than carbs
do (fewer bubbles in the fuel), and today's gasolines are formulated to be
sprayed through an injector instead of atomized through a venturi and
needle jet. If it is available in your area of the country, no alcohol
gasoline is the fuel to use.
High octane is of little value in our motorhomes due to the low
compression ratios of our engines, so, use the lowest octane listed on the
pump. If your engine pings on the stuff, retard the base timing a couple of
degrees.
As always, check your rubber fuel system parts often, alcohol laced fuel is
hard on them. If in doubt, throw it out. Always use barricade hoses.
There are many different configurations of fuel pumps and lines and
filters, some have advantages, some have disadvantages.
It is kinda like 5 blind guys looking at an elephant. Each holding
onto a different part, and trying to imagine the whole beast. Not exactly a
clear picture.
