RE: [Chrysler300] Vintage Fuel Pump Supplier





Using wood clothes pins sounds weird but seemed to work.  A wood clip on a steel line cannot be much of a heat sink but would help a little.  The wood “wood” be serving more as an insulator since the fuel lines were in the hot underhood air.  Might even have worked to physically stabilize the line from vibration which might have added to vaporization/bubbling in the line.  As I recall, the fuel pump was on top of the block at the back in my ’40 Ford.  This required sucking the fuel upwards of one foot so even a little bit of insulation or heat removal may have made the difference.  Mechanical fuel pumps are now low on the block so as not to require this extra foot of lift.  Still was not enough on our ’55 C-300 after buying and installing a rebuild kit in the pump.  Adding an electric pump back by the tank made all the difference and one could hear the pump pitch change as the bowls were quickly filled and the float valves closed.

 

Today’s fuel is designed for closed systems, carbon canister, high-pressure fuel injection, low emissions and not for ’40 Fords or ’55 Chryslers.  But it can be made to work.  Low-energy ethanol did not help MPG of the ’55 C-300 but I was able to get better mileage from our 345 CID “semi-hemi” Durango when TOWING the 331 CID Chrysler on an open trailer than when driving it.  I also get better MPG in the Durango when using premium fuel as its computer-controlled ignition system recognizes the decreased knock tendency of the system on premium fuel and advances the timing accordingly.   With only 8.5:1 compression ratio, the ’55 C-300 engine ran just fine on regular.  Higher and optional much-higher compression ratios enabled significant increases on the 354 CID ’56 300B engines with the optional engine cranking out 355 HP or 1.003 HP per cubic inch.  A first.  Now wondering why Chrysler did not bring out the modern hemi with that same time-honored magic 354 CID displacement—just for old-time sake.  That would equivocate to a 5.8 Liter engine.  At least they did bring out a 392 CID engine which is advertised as a 6.4 Liter engine.  I’d much rather have a “392”—and one with a cackle rather than a click as our ’05 Durango exhibits.

Had a guy tell me just the other day when I was relating Hi-Temp issues w/the F last summer while on the way to the PA meet, clip a bunch of wooden clothes pins on the gas line!!???

For a heat sink??

Any of you guys try that!??

I think all float governed cars , Carter carbs , will work over a reasonable range of pressures , I mean ?? what can be critical there? Think of inlet valve? Same as toilet valve at 100psi., just bigger float? (only kidding)

Number might be related to some pressure spec, as part of the fuel pump spec (has to be set, to design the spring force ) but carb will shut off 3 to 6 or so. Probably a lot more. I do not think they are 7-- but maybe. 70’s dodge truck has 318, NICE carter 2 bbl, like the front half of an AFB, “318 fuel pump” , same float and needle as essentially all of them have? Maybe they raised spec for more static pressure in the shut off line, with easy to boil fuels?. But even if it boils there, it just pushes through vapor when float opens ; might make more vapor at carb (which they seem to worry about a lot in 70’s , charcoal canister all that)

With respect to carb pressure , would be a minimum spec, not a max, to get enough flow needle open , to support HP. Maybe 318 pump is in fact a lot better ,given ethanol…

While on this, Lots of people think vapor lock happens in that line from fuel pump to carb..you see wraps , rubber covers etc..it cannot, --think about it!--as carb end is wide open when it needs fuel, , pump pushes fuel through it boiling or not. But at suction line near pump to frame or inside the pump , negative pressure at suction causes boiling, you might have troubles-- with suction induced low temp boiling. ( Studebakers known for this, some had pump on top of engine ) Vapor lock implies inlet valve in fuel pump has gas vapor around disc instead of fuel, cannot pump / draw in vapor with that kind of valve . Line to carb , after that point has nothing to do with that..

( A cynical Chrysler guy once told a Chevy guy, “ that line needs aluminum foil wrapped around it”, (once) . Lots of Chevy guys; they believe, they have both the magnet and aluminum foil, they swear it works great.)

They may fit and work, but they also put out too much pressure...7 pounds or more. This car requires a pump that puts out between 3.5 and 5 pounds.

Don't know this to be correct or not, but somewhere I once read that a more modern fuel pump from a 318 engine fits and works?

Hi Ron,

I have had 2 rebuilt in New York for about $130 ea including shipping - Arthur Gould Rebuilders, Inc. 631-269-0093.

Or obtain one from a salvage yard and have it rebuilt.

Hey Everyone -

Does anyone have contact information for someone that may have vintage Carter fuel pumps ?

Thanks,

Ron
