Lister petter metering pump - fuel line nipple *question*

[sandmanxx]

Can anyone give me a positive id as in thread type / standard on the fuel nipple ( metering pump)

I AM ATTEMPTING LOL. WENT TO LOCAL PARKER STORE AND HE WAS STUMPED. EMAILED UK BUT NOT
EXPECTING A RESPONSE. ITS EASIER TO SEE IN DETAIL IF YOU HAVE PUMP OUT OF A UNIT TO SEE THREADS.

THEY ARE COURSE THREADS
HAS A TAPPER AT END
USES METAL WASHER

that nipple is what the rubber fuel line from round copper/brass hard line with banjo fitting on it..

That nipple is part of the fuel pump / metering pump.

May be a an type fitting an-2 ...

But that is a us army/navy standard.. Its on a lister petter fuel pump lol

PLUS IT USES A METAL WASHER. SO IT LOOKS LIKE A AN BUT

Have you tried screwing a USS nut on it? Or check with a thread pitch gauge?

Thinking

bspp british standard pipe parallel - but that doesn't have a noted angle at end.
