Packard Forum Index » Post-War (1946-54)

2 pumps listed 48-50 and small 51 chassis but don't know differences. Different pumps used 51-4. I know one was a dual chamber vacuum setup for the senior cars, other was single chamber.

I know this sounds bad, but i can't read what the parts manual is telling me. I'm always confused trying to figure out part differences.

I THINK pages 215/216 of the link below is saying that all 23rd-26th use an AC pump of one or another part number, or at least the same screws for the same AC pump for those series.

Maybe i'll call kanter tomorrow and see if they know of any difference between a 1950 288 standard eight fuel pump and a 1953 (i think patrician) 327 fuel pump.

I KNOW the old pump worked on the 288. This pump came bolted to the 327 but i never heard it run or know for sure that it's correct or will work on it.

Ok couldn't get a link but if you go to max merrit and just search for group number 9.200, the 288 pump i have is the one shown for 48 to 50, the first option of four in the list:

The 327 pump i have is the second/third option (they're the same pic and part number) It has the plate style arm instead of the first style or last style.

That pump shows as for 51-52 all models, and 53-54 all except clipper.

The last model is a pump i don't have, it has a little cup that goes around the cam. it shows for 53-54 clipper models.

I wouldn't think that a clipper could be had with a 327 9 main in 53? I would have to think that the middle pump would be the correct one for a 53 327. Which would suck because "wrong pump" would be a great solution.

9 main 327 would be a senior motor or no? I really don't have a lot to go off of for the history of this motor now, the previous owner (dan yocum) passed and most of the info i got second hand from bigkev and dan's family who really wasn't into cars at all.

Motor number is L605910, which chart here shows as 9 main 327 with hydr. lifters, 1953, all senior models.

Both pumps are AC, can't really find an legible part numbers anywhere on the old one.

The 53 pump shows 9920 on the flange, which is what MM shows for 53-54 all models except clipper, which should be this motor.

I'm hoping it's a case of the wrong pump, but it would seem this one is correct for this motor.

From a vintage AC catalog, perhaps this will help.

To Cortcomp: Everyone needs a wife like that!!

As someone just stated, the FP lobe is integral with the cam and a few positions back from the front, not bolted on the front like a v8. I've never seen a deteriorated fuel pump lobe on a cam but that doesn;t mean it's impossible

NOTE: All Packard motors 6/120/356/288/327/359 whether single action or double action can take any of those fuel pumps and they will pump. The geometry of the arms
is identical

I'm really thinking you have a partially broken main spring in the pump, and as such the pump arm is already to far downward for the cam to do any real work on it.

Take the pump apart and check.

Only the '53 Patrician had the 327 cu. in. 9 main bearing engine. Congratulations if you have one of the engines in your Clipper.

I did get out my trusty starter button that i completely forgot i had and was able to bump it over and check it with a straw moving in and out, and then, ever so gently and carefully, with my finger while i bumped it lightly (coil and ignition wires disconnected!)

The lobe is definitely there, it can mvoe the straw about 1/3 or 3/4" to a fukll inch. I couldnt verify how muich because i was late for work.

Fred confirmed what i suspected, that the arm geometry and bolts patterns should be the same, that part numbers differences were for conenction port style and single/double acting.


I'm thinking i may have 2 bad pumps, or at least wore to the point where they're done now and were on the edge of failure, even if they both did last work on their respective engines. Have to go sometime right? I have a rebuild kit for the original one, i'lls tart there as kevin suggests, checking it inside.
