Will the Stratus OS91SZ-H engine mount work with the PS (pumped) version?

Edited my original post. Thought you were talking about the C-Spec PS.
With the new SZ motor, here is the deal. The case to front bearing is now 3.275” and the C-spec was 3.235”. That difference is .040”.

That oughtta explain it. The SZ-H PS has a nipple on the backplate and has a small piece of fuel tubing going from the backplate to the pump, it looks like the pump goes first, next is the CF mounting plate and 3rd is the backplate/engine. You will probably need a little longer piece of fuel tubing. Ive never looked at the SZ-H PS but thats how it looks to be.
