Yes, the lift pump on the M is 2 bolt and on the MW is 3 bolt.
I ended up just swapping the primer pumps.
Whoever put the primer pump in my car didn't put in the copper washer,
which accounts for that nasty leak.

Easy 15 min fix.

Has anyone here had an M pump modded by Tomnik or Dieselmaken?
Out of my budget, I'm sure, just curious. Anyone interested in buying
an M pump?
