Default Carter Lift Pump Tear Down..

Has anyone tore these things apart? I searched and searched and everyone just says the o-ring under the primer button is the only thing that can be replaced. I think I am going to tear it down for no reason anyways to see how it works and see all the parts. Get a bunch of pics.. Already got it all off. Tear it down tomorrow.

Oh, I still have the stock electric lift pump from my truck. It was still working when I took it off, giving 3 psi.

I found a little info that may help:
Quote:
The large O ring (R-54) has an I.D. 7/8 , O.D. 1- 1/16 , THK 3/32, the next closest size was (R-53) I.D. 13/16, O.D. 1- 1/16, THK 7/8. The small O ring (R-48) I.D. 9/16 , O.D. , THK 3/32. These are based on standard rubber O rings used in faucets repair. I sure there are other sizes maybe better or worse but at least this is a starting point or range to keep in mind.

I've seen that. I don't need to replace it I want to tear it down completely.. Just to see what it consists of. Maybe clean it out too. I also noticed I could completely get rid of the fuel heater assembly and all but since it bolts to that plate that goes behind the lift pump (in between engine and lift pump) I will have to make a new plate to simulate that it is still there. I thought the fuel heater was being used but my wires were melted so it must have got too much use lol. Figure if it has never been doing anything and I never notice then why have it there at all.

You can just by-pass the fuel heater. I did that on one truck and it has been that way for a few years even up here in northern Mn!! If you didn't know it you would never be able to tell by the way it runs.

If I take it off I can lose 1 ounce and get 0.001mpg more... It all adds up.

Just got a job to do on another Dodge Cummins 12V with the Bosch P7100 getting 8mpg. So I gotta put it all back together. It's all coming back apart when I get back lol.
