well said dave. I knew you for one were running the 12v pump off the helix 2 cam. Didn't know there were "many" others.
The VPs in my cirlcle are pretty tough.
I had a hard headed friend that I changed oil on his truck one time.
I opened his water valve on the fuel filter housing while it was running and instead of the healthy steam I get on my rig his sucked air cutoff and liked to never re-started.
I pleaded and pleaded with him to change his LP he ran it almost three years like that before he had a board falure VP high idle and dead pedal. Im still on my Virgin VP after 4 years or so of being tapped 30+ psi fp. Matter of fact I added the 7# carter on the rail before I ever tapped my pump wire.

well, this comes from cummins themselves pressure doesnt kill the VP, whether to hi or too low. its all about the temperature of the fuel which is used to cool and lubricate the VP44, too low of pressure means less fuel, which will cause it to overheat and go out, 99 percent of the time thats the cause, the only reason some say not to run past a certain pressure is because the rubber diaphram inside the pump can burst and then its out. so on a used vp44, say one thats had a lift pump failure, it may have heat cracks in the diaphram which when running too high of pressure, it could rupture. so its a double edged sword. i see no problems running 45 psi as logn as you know for a fact that you havent had an overheated diaphram.

So back to the topic of the OP: Draw Straw I install. I've just finished it and put the tank back in. Upon raising it and tightening just one side of the tank support band/straps, it looks like the top of DS head (the anodized blue part) is almost flush with one of my bed cross-members. Has anyone else noticed this? I'd hate to have anything heavy in the bed putting pressure on the top of the DS. I'll post up a picture in a bit.
