Engine/Transmission (1998.5 - 2002) LP pics

[CFast]

I need a new LP and would like some pics of how you guys installed your LP's on the frame. Did you guys drill through both sides? Thanks.

Here's a pic of mine. It's attach with self tapping sheet metal screws into the frame - through one side. I put a bicycle inner tube between the mount and the frame to isolate vibration.

This weekend I should hava complete write up done with pictures. Stay tuned...

Fuel flow is from left to right, the added plumbing seen is my fuel bypass valve to slightly reduce overall system PSI, and provide a fuel flow path AROUND the pusher in case it fails...



I drilled mounting holes for 1/4 screws into the side frame - it's a good idea to incorporate some form of additional rubber isolation for sound deadening over and above that provided by the pump - these babies can be LOUD when running - some suitable rubber like short sections of appropriate hosing on the mounting screws, or a rubber "plate" between the pusher mounting plate and the frame is a good idea...

In regards to pusher pumps, if the OEM pump fails will it block the flow of fuel from the pusher pump? Also, what pressures are you guys seeing with the pusher pump?



TIA

Failed pusher *might* block fuel flow if stalled in the critical part of it's rotation - at best, it WILL restrict fuel flow.



Without my homemade bypass valve, I was seeing as high as 26 PSI at idle - 22 at cruise, 18 at WOT - all pressures dropped by about 3 PSI with the added bypass, which was one of my goals - with the pusher shut off, I still see 15 PSI at idle with the stock LP alone - which was ALSO my goal with the added bypass valve...

Gary thats a nice looking setup. Just a couple questions, how much $ do you have in it and if the stock lp fails will the pusher still provide fuel to the vp. Im interested in changing my fuel delivery setup and still trying to decide what route I want to use,Fass,Preporator,other?

Thanks for any advice.

Between reading these and the others... you should have formed some fairly good ideas of what you want to do.

Thanks for all the replies. Sticks it must have taken you longer to type that than to do it. Hopefully I'll get that done next weekend.

Yeah, well I blame a teacher I had in elementary school for that.

Aaron, my setup cost just under $100 - Carter 4600, Fram filter, Radio Shack relay, Cummins LP cable extender, and other misc. stuff - the stock LP quit running on our last RV outing about 300 miles from home - still had about 10 PSI at idle thru the stopped stock LP, dropped to about 5 PSI towing over the Tehachapies coming on in... So at least in my case, the pusher WAS able to flow sufficient fuel thru the stock LP - but I suspect if the LP managed to stall in a "closed" part of it's rotation, things might be somewhat different. All in all, I'm VERY happy with the way my setup functions, overall PSI is right where I want it, everything seems simple and reliable - the stopped stock LP apparently was a poor electrical connection at the plug - it would operate properly for about 30 seconds, then get erratic and quit - did that several times on the way on home when we stoped at rest areas, etc. - but when I took it off and checked it off the truck after installing my backup LP, it checked out perfect - full PSI for as long as I wanted to run it - and disassembling the pump portion showed NO problems whatsoever... - so now IT is my spare!
