I recently bought a rebuilt fuel pump for a '49 panel I'm trying to sell. I bought it from a person on eBay who advertised it as a pump for a '51 car with a 226 six cylinder. The panel has a 226 six cylinder. Before a placed a bid on it I checked one of the reproduction parts dealer's web site and they listed the same number for both the car and the truck. When I got it it turned out to be a nice pump with good suction but the inlet and outlet ports were smaller than the stock truck pumps I have. I was just wondering if anyone knew for sure that they used a different pump for the car than on the trucks or did Ford change them across the board in '51?

I am just going to keep it as a spare for my F-2. I'll have to find a couple of fitting adapters to make it work. I got it for less than $20, including postage so I'm not going to complain. I figure even if I reduce the inlet and outlet it still could get me out of a jam if I needed it.

 

A lot of them come with brass fittings screwed into the in/out ports, did this one? Could you swap them from your old pump? Check a V8 pump if you have one around.

 

Ross,

No, none of the pumps I have have brass fittings. I have the original from the truck that some one forced regular plumbing fitting into, a used one in my parts stash and one that is installed on my F-2. The eBay pump is identical to the other pumps I have except for the smaller openings. I wasn't able to notice them in the eBay ad and I'm accepting the responsibility of that. I'll have to find a couple of brass fittings to make it work. But by doing this I'll be restricting the flow a bit because the truck pumps are almost twice as large.

 

I don't know for sure whether the ford changed over to different fuel pumps for cars and trucks after 1951, but I did have a few of issues related to this topic that I'd like to discuss.

First, the 1949-1951 repair manual shows that 1949-1951 truck fuel pumps have the same part #'s (7HA 9350-B or 1HA 9350) for either the 226 or 254. From some of my previous parts research, I pretty sure that the first position is the series number (7 = 48,49; 1 = 1951), the second position is the engine code (H=226, M=254) and the third position is the car/truck designator (A= auto, T=truck). Also, the 1948-1956 parts catalog shows that all flathead 6 cyl truck engines can use the same fuel pump from 1948-1953. But the original setup was probably different... so then these #'s represent replacement parts, right?

You guys probably know all of these details already, but wouldn't this info suggest that fuel pumps for flathead 6 cyl cars and trucks are at least interchangeable (plus/minus adapter fittings) until 1951?

Second, this vendor suggests that the inlet and outlet port sizes changed over for flathead v8's in mid 1951, but doesn't discriminate between cars and trucks (click on the Q&A tab):
1952-53 Flathead Ford Replacement Fuel Pump - Speedway Motors, America's Oldest Speed Shop

"These fuel pumps fit the 8BA flatheads of 1952 -53 as a direct replacement and the inlet and outlet are 1/8” NPT. The earlier ’49-50 pumps number 56052654 have ½ x 20 inlet and outlet. ’51 was the switch year and normally the early ‘51’s had the ½ x 20 straight thread and the later 51’s had the 1/8” NPT thread. This is the needed consideration for an original replacement pump."

This suggests some (8BA - car only?) fuel pump interchangeablity (plus/minus adapter fittings) until 1953, provided v8 and 6 cyl fuel pumps are the same (which I believe they are, except for the rocker arm…)

And finally, for comparison, this is the aftermarket pump that came with my truck:



Anybody seen one of these before?

 

Call Mac from VanPelts He will know.

 

See the brass adapter fittings? That's what I'm used to seeing, especially if they are covering more than one application.

 

None of the fuel pump I have have the reducer fittings. I'll have to see if I can find a set to use on the new pump.
