Advice For Older Jeep Owners
Now that MTBE has been removed from gasoline, the government mandated
replacing it with 10% ethanol. If you are running an older engine (like
the '64 Olds V6 in my CJ), the alcohol will tear up the fuel pump and
hoses. I speak from experience when my '61 Jeep died and I had to call
the flatbed to get it home. Fuel pump pressure had dropped to about
1psi. I replaced the stock pump with a Purolator/ Facet electronic pump
(around $40) and get a steady 4psi at the carburetor. (If you are
running one of the older Dupree plunger pumps, be advised that the
alcohol will tear up the bellows in it too. There are no replacement
parts to solve the problem.) Be sure to replace the old hoses and fuel
filters too. Alcohol will tear up older rubber hoses and they can plug
the filter inside the carburetor inlet.

Re: Advice For Older Jeep Owners
Same goes for the 258 engine! The owners manual states 'no' amount of
alcohol is safe in them. My float needle maybe lasts a year before
getting gummed or crudded up.
Do you know about the fuel pumps on those?

Grump, I thought this was going to be a thread full of advice for us old
Jeep owners, not just owners of old Jeeps. ;)

Re: Advice For Older Jeep Owners
Actually all replacement pumps and carburetor kits made since about
1985 (?) are made to be used with alcohol. Before that period the best
valves, diaphragms, and hoses were made out of neoprene, which dissolves
in alcohol. Another bad rap we got during the japanese invasion.
