I have a 2011 ISL high pressure fuel pump. It shows a part # FP90596-02.
I have a 2016 ISL pump ,part # shows an FP92708-03. I need to know if they will interchange?

Personally, I would not know the answer to that one.

Myself, I have never taken a wrench to an ISL engine. Only have done programming for them.

maybe someone else knows this answer.

Why not just get the right part# and be done with it.. sell the incorrect one if you have it as a spare.
