      The arm from a real "R" pump is longer and won't work with a Chrysler pump.
      I don't know how to best cool the arm after bending. I know you shouldn't bend it cold. If you let it cool slowly, that's annealing it and it will be soft.
      Sword makers used to impale a live captive to cool a sword properly. Maybe use an evil vendor...

        Mike,

        Could you provide the link to the diagram of the arms?

          The diagram of fuel pump arms is at:
          http://autos.ph.groups.yahoo.com/gro.../view/9963?b=1 .
          It's a tracing of the edge of modified and stock Chrysler fuel pump operating arms; done on 1/4" graph paper. It shouldn't be hard to count squares and redraw it on a blank sheet of graph paper, if it's hard to print exactly the right size.

            Mike,
            I couldn't access this link. Do you have to be a Yahoo member or Avanti Discussion Group member, or both to access?

              About new replacements for "R" pumps:
              My Avanti came with a modified M6270 Carter pump, when I bought it. Summit still has them, for $77.95. That's a satin finish, strip pump for small Chrysler engines. It has three valves, and 1/4" NPT ports in and out. (An "R" pump has two valves, and is 1/4" in and 1/8" out). The diaphragm isn't as big around as an "R" pump, and the valves are a little smaller. It's supposed to flow 120 gph @ 7.5 psi.
              To use it on a Stude, the pump has to be taken apart, and the operating arm heated and bent. After the final heating, I think you should cool it quickly, for hardness.
              I posted a diagram of the stock and modified arms, that I traced, on the Yahoo Avanti chat group. Any of the small block Chrysler pumps should convert the same.
              If it's for an "R2" you also need to drill and tap the boss for the boost reference line, and plug the atmospheric vent. That's easy.
              I prefer the real "R" pump; but I think this is a good substitute. I don't think it should be sold as the "R" pump without explanation. I think some vendors do; for big bucks.

              Here is the drawing that Mike M. references, showing the modification to the Carter M6270 fuel pump for use on a Studebaker V8:

                  Dave Thibeault has done all the work, he sells replacements for both R-1 and R-2..he adjusts the arm, and taps the top for R-2 examples.

                  I also have purchased from him pump kits and never had any problem.

                    Mike M has a sense of humor!! He sent me a package, but I opened it
                    up and didnt see the parts right way. The sly guy taped them to the
                    top of the box with a note "I bet you thought it was empty! Mike."

                    Anyway .. here are pictures of what SHOULD be included in the kit :





                    Rubber removed from special washer/holder :





                    inside of washer/holder :





                    Dime inside (size)



                    Parts included in kit - some lame bin washer :





                    I got an Email back from S.I., they apologized for the damaged part &
                    told me to ship the kit back to them, than they would send another, or
                    I could have them bill me for a new kit, and send the bad one back
                    after I receive it for credit. Neither of these options I liked. I asked
                    if they would send just the rubber part. Will see what they say.

                    EDIT : I will take dimensions from this part, and make a CAD drawing
                    so I can get a quote for making them. Maybe S.I. will be interested.

                    Pulled the fuel pump off tonight, I will start a new post covering the
                    rebuild proceedure along with the helpful instruction from Mike M.

                        The excellent Pics, I am sure, do not work now Tom.

                        Update: I unblocked something called EmperorJordan which sounded bad, so I had it blocked with Webroot AntiSpyware, whatever it was, that makes the Photos display now.

                          So Tom; will the new improved, like the original stem Oil Seal holder ring you are making fit the Cellar supplied seal?

                            Mike M:

                            Sooo, where do we obtain those beautiful and necessary diaphragm stem seal metal retainer rings and replacement seals to fit in them.

                            Thanks, Dean

                              Parts Cellar, who makes the kits some Stude parts suppliers sell,
                              ( http://www.maritimedragracing.com/an...rts_cellar.htm ), sent me a couple of the formed seal retainers. They insist the flat washer is all that is really needed. I had gotten a kit from "SI" with the flat washer, and a kit directly from "Cellar" with the formed retainer. I asked "Cellar" to send me a retainer to make the "SI" kit usable. I've been told that the seal and retainer are actually "AC" fuel pump parts. You might try salvaging retainers from a used AC pump.
                              I notice in a drawing at the "Cellar" web site, a pump with a double stem seal, (four pieces). Maybe this is how the seal is normally used. Of course, using a thicker seal would also shim the diaphragm spring, which controls fuel pressure.
                              On R2 pumps, the stem seal has to hold the boost reference pressure from the supercharger, as well as keep oil off the diaphragm. I doubted the AC seal was up to the job. Cellar insists that it is.

                                So Mike; does that mean that if Tom made some seal retainer rings, they would fit the current seal in the "Cellar" kits then, or is the AC seal they sent you slightly different than theirs?

                                They told me (at Cellar) that Carter [u]would not release</u> this special Proprietary Carter Patented "Seal" for them to re-produce it, even though they, the Federal Mogul Corp. owner of the Carter name, refuse to make ANY replacement parts for the former Carter Corp. design Pumps, OR their own! [xx(] Makes 0 sense!

                                I believe it was the same with the valves, so they had to make do with a washer and some rivets!

                                I agree, the seal does not center with that washer on there, UGH!
