HIPO fuel pump 3939S with wrong Actuator Arm

wmcurryjr · December 17, 2008 at 5:34 PM

Hi,

Does anybody have a fuel pump actuator arm that allows 2 springs to be used? I have a 3939S rebuilt by ford but it only has one spring on the top side. The arm doesn't seem to have the notch for the second spring to sit correctly?

If I find an original arm, can it be replaced on the unit by removing the pin without taking apart the unit? I have an original spring but wrong arm to mount it in?

Let me know,

Wally

Fred (c6zz) is the expert on disassembling these pumps, hopefully he will chime in.

This is a subject with which I am all too familiar. The arm that you seek will be very, very tough to find and you can read about in my posts on the Restoration topic of this forum. I have attached a link below:

I was unable to find cores much less any parts for this project so this one will be tough. I figure that the dimple in the arm can be made and I have devised a way to do that. The arm is a trick in itself to remove and I made some special tools to facilitate that so as not to damage the pump. Some are easier to remove than others. If you send me your complete pump and spring I can get this done for you while I still have a proper sample arm to work with.

Fred, you're awesome.

Give me your address and I'll get it mailed to you.

Thanks, Wallace Curry

Consider yourself lucky to have a pump body. I have nothing for my engine....still looking for a good core.
