Here's a really dumb question considering the source, BUT... I know we have a lot of quality machinist types in here, some of whom may be retired with nothing better to do... ;Really Everytime I think of this question, I'm not at home, or in easy reach of an IP, so....

Can someone tell me ... if your wanting to screw something into the fuel inlet of a "naked" DB-2, what is the thread nomenclature? I'm thinking it is a metric 12 mm something.... Anybody? And yes, I asked my pump guru and he doesn't know either. LOL

Mine was a -5 straight thread- 1/2 20, IIRC, maybe a -6thread-9/16 18, Anyway I put an o-ring style fitting in there and it works great.

Yeah I'm thinkin its a #5 o-ring. I had a fitting in my collection that worked when I put an o-ring around it. I had a hose shop trying to get me the right fitting, they are hard to find, at least mine was because I needed it to be #6AN on the hose end.

Ah! That's exactly what I was looking for. Yes, I guess what I want is an ORB #5 to 6AN.

Hello Mel. I deal with this stuff in the hydraulic world on a daily basis. -5 male ORB (acronym for "o-ring boss") is a little obscure as -4 and -6 are far more common. Let me know what you need to attach it to (are you looking for a flared connection to go to tubing or a flexible hose?) and what material you would like it out of (steel, brass, aluminum) and I'll point you in the right direction.

Now I remember, the pump shop gave me a fitting that was 1/4 ORB and #5 JIC because it is what they kept in stock for another application, but if you are looking do do a fuel inlet line, a #6 jic would be better because it gives you more options as you can get Aeroquip lines that will attach to that size if you want.,but if that isn't important, the 5 will do just fine.

I'm pretty sure if you say exactly what you are trying to do, somone here will probably send you what you want for free. As much help as you've been to others, I'd say you deserve at least that much. I don't know squat about the fuel system yet, or I'd go out and buy it, or out in my shop and make it, and have it in the mail tomorrow.... lol

Well I hate to blow the covers off a good poject before it's even under way, but I'm planning on offering a kit to replace the filter head to IP hard line with a fancy show quality stainless braided hose and colorfull XRP fittings. Just a little something to snaz up the engine compartment and solve the problem that people with Hypermax Intercoolers have once they install one... that is, the inability to change fuel filters without taking something apart. A perfect accessory for a Moose Pump. I've got all the pieces I need except for this one. My guy at American Speed is trying to find me what I need, which is this ORB (thanks for the acronym explaination ;Sweet ) 5 to AN6 deal.

Well I'm not a current Moopse pump owner but I would be interested in that particular line since it appears Goldies has developed a fuel leak and that line appears to be the culprit at the IP connection.;Sweet

Mel you can also use a -5 to -6 union and just slip an o-ring over the 5 end, after turning off the -5 taper. thats what I did.

PM sent Mel
