I went to a local diesel shop, that distribute denso and Bosch, i gave him the bosch and denso number i got here. He told me he had something better and sold me this. Hope is screw in. The black sleeve is the pump you simply push down and will pump

OOooo nice..... Does it work? for the 3B right? I was just about to order one from SOR, but if thats a better unit I guess ill just get one of those!

I need to figure out how to get a key on the existing one to unscrew it in place, tight spot without space to have a wrench turn. This one is much smaller then the OEM one. Yes for 3B, i hope it is the same thread but won't know until i remove the other one.

BTW cost me 28$
 
I had the exact same problem of the the leaking primer and I just replaced mine last weekend. I used a crowfoot to get the stock primer off and then also to tighten the new one on. I also replaced the copper washer and the plastic valve as well. The primer was made by a German company, Flag. I got it from EBI. www.extremebends.com

What is the size? 21 or 22mm?
 
The crow foot kit i bought today at napa won't do, the opening is not has big has the crow foot it self, so unless i grind what is exceeding, crow foot won't do. I'm out for the weekend but monday i will go find a set of short key. Crow foot are good for bolt head, but won't go over the OEM primer, neither the one i bought.

is your crowfoot this style? or more the almost rounded kind(multipoint). It's this style that should work. Almost like an open end wrench, but short to use with a long extension and ratchet.

The one i have are not like that, what you are showing would work.
 
The Bosch 2 447 010 033 is what we have been using the last while. Looks like the primer pictured above.

I ended up heating, bending and grinding a wrench to get in and take off the stock primer. Crows foot would be better if you can get one local that is thin enough.

I've used a bench grinder on many a tool. just grind to fit. What's sad is when I have to grind my snap on tools....

Finally got the crow foot i needed, (24mm) The bosch fits prefectly, don't loose the brass washer...and when removing the old one be carefull there is a spring and a plastic valve in there that you need to reuse.

Ah good to hear. 24mm is a good tool to have around. I might sacrifice my wrench at the time. As these sets sell at C-tire for 20 bucks or so, when on sale.
 
Sorry i thought you were talking about crow foot kit. Those key would be useless to remove the OEM pump, unless you are ready to bend them!

I have to mention it is useless specificly with my truck (83 BJ42), since i have power steering.

It's all a lot easier if you remove the lift pump first... two 22mm fittings, and three 10mm nuts with washers (and a little diesel here and there).

It's easier to do on the work bench if you're having trouble doing it in-truck.... just did one today, also cleaned the lift pump assy (no water separator = rusted parts:rolleyes: )

good idea, but then would you not have to buy a new gasket for the lift pump? Knowing my luck I would destroy the old one coming apart.

Where as the pump by itself comes with the gasket alone.
