MEP-803A Injector Thread Size

[jmpratt]

Anyone know what the thread pitch is on the 803A injectors (or injection pumps)? I'm building a bottle jack injector tester and I need to know what size fitting to get.

Someone will have to take one off and look. The parts manual doesn't brake the hard lines down to individual parts.

It's M12 x 1.50 . Anyone know where I can find a male flare fitting? (like the connection end of an injector)

Try a Parker Hose dealer, Maybe Grainger.

2nd vote for a Parker dealer. They seem to have everything when I need stuff like that.

Side note, whats the pressure expected for these injectors to pop?

Couldn't find anything so I made my own. I've got the M12-1.5 die. Took a piece of 1/2" bar stock, turned it down a little (11.78mm), put threads on it, drilled a hole through it, and added a countersink to hold the flare from the pipe. Easy if you have the tools. I'll put up pics when I'm finished.

Don't know if you found the info in the Onan book, but here's the Stanadyne spec sheet link.
