There is a Fuel Pressure Regulator. The 3500 uses a return less rail. So the fuel pressure regulator is somewhere down the line. Likely at the lower part of the firewall or even under the van.
Sorry I didn't see this thread earlier. I suspect the fuel pump is getting tired.

I don't believe there is a FPR on the Montana SV6 The FPR was my first thought, I was sure that was it. I look, returnless. Hmm, look up the part, non listed, check the manual, no procedure on changing it. Seems to be no FPR on the SV6

OK, right by the filter. I'll have to take a peek. But I looked on rockauto and autozone, neither list a FPR for the SV6. The problems it has indicates to me a bad FPR. Hope to find it hiding under there.

I'll be sure to do that. Looks like a regular old FPR just like I have sitting in a drawer. I have like 5 of them. Wonder why I can't seem to find a replacement part.
