28 dictator fuel pump

Recommended Posts

The GE Dictator '28-29 1,410,001 up used an AC type A pump #855088. as did the 1930 GJ Comm. 6, which also used #855089. The 1928-29 GB, GH Comm. 4,039,801 used #855089. The 1929 Comm. 6 4,070,501 up used either #855088 or 855089.

 

I expect the correct pump to have 5088 stamped on the surface at the top of the mounting flange.

This is the series A or model A fuel pump. Does the mounting flange shape match the car? The top may be different to yours, this is a "typical" pump of the series.

Auburn 1929-30 used a model A pump, as did Buick 116, 121 and 129 of 1929;

Franklin 1930;

Graham Paige 615, 621, 827, 837 of 1929;

Graham Spec. 6 1930, Cust. 8 1930;

Oakland 212 1929;

Oldsmobile F-29 1929;

Pierce Arrow 1929 & 1930.

 

None of these are common, so good luck!

 

The top goes through to 1940:

Here are the repair parts:

This came from an ebay listing. If you bought it, you would know which models used the same arm etc. and could easily find the parts you need.

The original pumps were Stewart Warner.They were sued by AC for patent infringement .

In order to satisfy the judgment against Stewart Warner , Stewart Warner turned over the dies to AC.

AC produced some pumps with the Stewart Warner logo on them or awhile.

here is a picture of the fuel pump mounting for the dictator engine.  the two bolt holes are diagonal to eachother,  and the rocker arm must be fairly long, about 5", to reach the eccentric on the cam

OK, my AC book is spreading misinformation. :( That looks more like a series B mounting. What is the distance between the bolt hole centres?

 

Here is another take on it:

Here is another version, from the National Data Manual (via restorecarclassifieds.com I think):

You can see the Stewart Warner pumps used. The earlier ones appear to have been AC.

 

P.S. What is the engine number? Could it be a later engine?

What is the casting number on that block?

I believe the fuel pump on the 1928 looks like this Pierce pump.

The arm would be different but the bolt pattern was like this.

If they made the change to series B earlier than the books show, it would look like this (top would be similar but different fuel routing):

I don't yet know what top was used, but later in the '30s it was straight through inlet to outlet. The second one way valve would probably be like the one on the right in the LH photo above, not with a dome as on the left. There were two series B bases, with a number stamped on a boss at the top of the mounting flange. One type had a screw above and in the middle of that boss (RH photo), the second has a screw each side of it. I don't know what yours should be like.

spinneyhill and rbk:

engine number is ge21864

casting number is 127353-3

casting date is h-4-13

I got the engine sitting back in the chassis, things are coming together and looking better!

I will get some pics up (I forgot my phone at home again)

thanks - terry

btw, I'm calling off my search for front fenders, the ones I got looked better than I thought and I think I will use them.  (still looking for some better rear fenders)

Here is a 1929 Dictator engine with fuel pump. This is probably what you are looking for:

image.png.34bb9eddf62f2a928180540ed462cc18.png

This photo comes from

 

The 1929-30 Commander 8 used pump 5408 or 5360. The '29-30 Dictator 8 used #5360 while the 1930 Dictator 6 used #5402 (see the chart above). There are all series B pumps. According to this chart (a continuation of the one above) they all use the same arm and top with it set in different positions.

Here is one that would be a very good start. Maybe the arm is the same but expect to have to change it. It is the right model and shape.

I called Then and Now Automotive in Weymouth, Mass. to see if they had one of these fuel pumps.  They don't have one in stock, but can assemble a Type B pump for you for $295.  Sounds pricey, but it's an option if you can't find a used one.  They specialize in fuel pumps for antique cars, have many other parts, too.

 

Their web site is at http://www.then-now-auto.com.   Phone is 781-335-8860.

thanks everyone for the information and options.  

Gary, I checked that website and that was real interesting, thank-you.  I probably will be in contact with them.\

as usual I have been scouring ebay for ideas and options, but heres a couple pics of pumps I had in the shop, one (yellow) from Hough payloader I bought ten years ago, and another from the inventory when I took over shop from my retiring boss.

I appreciate everybodys information, pics, and suggestions on this, it has helped a lot.

thanks - terry

Good one. That is actually a universal top and can be fitted to just about anything using the appropriate outlet port.
