Subject: RE: [Chrysler300] ethanol-eaten fuel
pumps Rob, When
I revised my 300H, I did the same thing you did. I carried it one step further
by “modifying” my mechanical fuel pump. I removed the pump, removed the pump
arm, and filled the inside area where the pump arm pivots with PC7 (two-part
epoxy mixture). I made a gasket to cover the whole pump where it seats on the
block, and re-installed the pump. I connected the fuel lines to the “dummy” fuel
pump to make it look original. It never gave me any
problems. Mark From:
Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of
'Rob Kern' robkern@xxxxxxxxxxxxx [Chrysler300] Hello 300’ly to
all!
ANATHEMA!! I gave my 300C fuel pump that worked swell to John Begian for
his C project for the cost of shipping and replaced it with a 5 psi electric
pump from Hemi Hot Heads. It is a non-racing pump that is engineered for
dual carb hemis. I located it on the frame rail where I had my electric
priming pump in front of the passenger rear wheel with a stone guard beneath
it. I insulated it from the frame rail with a rubber pad so it doesn’t
make a racket like a woodpecker on the roof. The major reason was vapor
lock. The 392 mechanical pump is just beneath the exhaust manifold and the
metal lines go right next to it on the rise to the front fuel bowel and hug the
water pump area for the upper radiator hose connection. I am fortunate to
purchase ethanol free unleaded 91 octane easily in Lawton, Oklahoma. Still
modern fuels burn up to 200 degrees F hotter than the ones formulated back in
the time of the early letter Cars. There is a reason that fuel pumps I now
realize are in gas tanks or away from the engine compartment . Probably the
vapor reclamation (EGR?) circuit in modern vehicles has something to do with the
location also. Soooo.... the engine starts up immediately since the pump
turns on when ignition key turned to on before engaging the starter, pure gas,
no diaphragms to fail (near and dear to a soon to retire gyn, 27 days to go),
and smooth driving at all speeds and all temperatures without any hiccups.
You purists can do your thing, but here is a solution that works well but is not
concours correct. Rob Kern From:

Maybe I'm just
lucky. I've been dealing with fuel system adversities for more than 50
years and I don't find things to be a great deal worse now than in the
past. I've not checked the alcohol content in local fuels in a long time
now, but I suspect that here in Florida we still have less of it than in many
parts of the country. Between 1995 and about 2004 I never saw local
content to be greater than about 6percent (measured with a rather crude
test device, careful monitoring required because of 2-stroke sensitivity).
My sense of smell is not very acute, but it seems that now we have less ethanol
than at some times in the past because I hardly smell it at all now most of the
time. A few months ago I disassembled the fuel pump on my C300 just
to make certain that it was still in good shape before driving to
Wisconsin. What I found was no noticeable deterioration of the diaphragms
and it remained clean and corrosion free internally. The pump was a new
Airtec from Carquest in 2008. I drive the car a little bit almost every
day, refuel it about once a month, and have now accumulated just over 21,000
miles since I started driving it. There's little for me to complain
about. ---------------Marshall

I
also have had 2 fuel pumps rebuilt by Arthur Gould in New York - no
problems. Doug

Three
different 300s and 3 ethanol-eaten fuel pumps. They worked long enough to push
the diaphragm chunks up and
clog the lines. Has
anybody had any luck finding ethanol resistant fuel pumps or can recommend a
rebuilder using ethanol resistant internals ????? Thanks Jeff
