Walbro 450 pulse modulated capable?
 

So I just got off the phone with a tech at Walbro. He has assured me that the Walbro 450 LPH pump is pulse modulated (variable voltage) compatible, and will work as a drop in replacement in the NNBS fuel systems. Im very curious to try it to confirm for everybody here, especially the guys that waited forever for the Squash system that never came about, but my return system set up on my truck is pretty much done. I cant rip out 1000 bucks worth of AN line, AN fittings, regulator, and rails, just to see if this works. Please tell me someone here has either done this already or is willing to be the guinea pig?

You know I'm going to do it. Waiting on pump.

I was hoping you'd post up saying that. Let me know how it ends up. I really hope this ends up being a drop in pump swap for us.

Yes, it would be nice to just install the 450 and ride.

I was looking at those a day or so ago....wondering if they'll drop into a 2012 Ram. Guess I have some calls to make tomorrow.

Been looking for an upgrade to stock pump if this works i may shoot for this keep us posted

Why wouldn't it work? The squash setup used the Walbro pump.

With a return line.

The Squash set up basically bypassed the FPCM and you still had to make it return style. This, from what I was told from the techs at Walbro, "should" be a drop in replacement in the NNBS trucks. Id be the guinea pig if my fuel system wasnt almost done right now.
