WN/G oil pump

Hi all,
could someone know if Ariel oil pump part 2212-29 is the same as Triumph oil pump part 70-3072. They look on picture.
Thanks for your answers.

There is a Triumph pump that is almost the same, both designed by Val Page, but I don't know the Triumph number and the mounting holes are slightly different. With a file you can make it fit. New uprated pumps are available for the Ariel.

Hi Roger,
thanks for your answer. As you can see on the file attached, the left one 2212-29 was on my W/NG and the right one 70-3072 is a Triumph one.
The holes are the same, but the body of the Triumph one is too longer, and can not be fitted on the my bike.
Someone got experience with that or advices ?
Thanks all.
Didier

You have to cut the body and shorten the plungers but that pump puts out far too much oil. Look how much bigger the diameter of the delivery plunger is. I put one on my VCH for a short time. The "Porting" holes don't quite line up either. Nev

and if you cut the plungers they become open tubes, they are hollow.

Not all of them If you get one that is you have to plug it. Ariel singles don't like a lot of oil was always the word with racing. They don't scavenge that well and run hot due oil drag. My W/NG is my most used bike and it's had no engine attention since 1997 and it's done about 16K miles with the ORIGINAL oil pump and 3 comp rings only.. . Nev
