I'm not sure of anything anymore. I thought the damn thing had a FPR. I know the injectors are rated to flow at 55psi, so there has to be a damned FPR somewhere!

You would think. But I followed the fuel line all the way from the tank to the rail. I don't recall even seeing a filter.

Yep, a FPR will cause hard hot starts. And it'* easy to test that. Pull the vacuum line and smell it. If you smell gas, the FPR is bad. However, in the case of our Montana, there is no FPR. But for the transport, it is something that should be checked.

I must be getting bad info from AZ alldata says Montanna has FPR on 2/wd and all wheel drive. Been following this post for awhile, got e-mail notification, thought I would chime in.
Good luck
