I have a late 50's to 60's model ford 4000 with a roosa master injector pump. I am trying to rebuild/fix the pump. It doesn't have any pressure. I checked the shaft for the gear drive and the o-rings are gone. I don't know how to get it completely apart. I believe there is a snap ring at the top. Does anyone have any info sheets or advise for a do-it-yourself pump job?

Call Mike at Diesel Specialities in Albert Lea, Mn. 1-800-966-2198. Two over-the-phone diagnoses and repair estimates were right on the money, and both work fine ever since- 3020 and 4430. In fact, 4430 recommendations were done by local mechanic per his advice. Injector pumps are not for the untrained.

Experience is the best teacher because it costs the most. I tried to help out two injections systems, the first try worked well, I didn't have to get into it very far. That experience gave me false confidence to tackle the second system, which was off a 4000. When I finally got it repaired by a professional. It ended up costing twice as much.

Some repair shops give you two choices, a.) off the shelf swap with your pump at a fixed rate. b.) A range of cost from best case to worst depending what is found wrong with the pump, a crap shoot. Hopefully I never have to be faced with that decision again but if I were I would always pick the pump swap with a fixed price. There are shops that will talk about your pump over the phone, give you prices etc. and then you can mail the pump in and have it turned around in about a week. That�s what I ended up doing, there wasn�t a shop close by for me. Cost nearly $400.00

You can do some of the minor seal/ gasket repair yourself, but unless you are a trained diesel injection pump specialist, this job needs to be done by a reputable repair shop. Your pump can be sent in for repair, which takes time, or you can buy a reman. pump at your dealer and they will give you core value for your old one. Either way, plan on spending many hundreds of $$$$.
