I am thinking I will be changing my lift pump this weekend. Vuclan Mechanical FP from Geno’s will be in tomorrow and I will verify fuel pressure. Seems like my foot slips of accelerator while driving down highway, about once every 1,000 mi. I am also looking into APPS (already did the reset with no luck). I have gotten a CEL twice with no real codes, 0500, 1693, 1694; light goes away after restart. Anyways, I did some investigation here and decided to go with Campain Fuel Kit, P/N 4090046. Cummins thought they had the kit ($172!!!) but couldn’t find it on the shelves. Kit breakdown is as follows:

3164754- 1 Electrical Cable
3408705- 1 Pressure Switch
3963983- 6 Sealing Washer
4918413- 1 Banjo Connector Screw
4943048- 1 Fuel Transfer Pump

They did not have all of the components of the kit since it was obsolete but convinced me that all I really needed was the fuel transfer pump. They charged me $162 for pump. Much more than I had thought but couldn’t find cheaper in Houston area, Freightliner also claims to have the kit for about $25 more.

Will this fuel pump alone act as a direct replacement for my truck or do I need some of the other parts in the kit? I can always return it and go to Freightliner. If I find that I don’t need a fuel pump, I will always have one available in the garage. Truck is stock and will likely remain so.

 

I was fortunate to purchase a couple of these kits for $48 each and just installed the pump and sealing washers last month works fine (for a crummy Carter pump). Some members were able to call other Cummins distributors and locate the obsolete kit.

 

I was able to locate two here in Maryland and still have one for spare. I guess I will be looking to see if I can get anymore. Sounds like they are getting hard to find.

 

Call Southern Plains in Dallas.
No questions asked, great service and quick shipping.
(i got two) sold one and installed the other till get inspired and mount the
Glacier Kit.
