I have a slightly mod'd 2003 CTD (see sig) with 103,000 miles on the original lift pump. It's on the fuel filter and working fine.

Question. For extra insurance, should I:

1. Go with advice in Turbo Diesel Register 56 article: KISS principle...Buy a spare Cummins lift pump. It was sufficient for for all boxes tested (100HP and below). COST: $180 and I've got backup I can put in on the side of the road.

2. Go with a FASS 150-1003 pump. Have the ultimate deliver at a rock steady 15-17psi. Cost: $430 + 225 to install and I've got no backup on the side of the road.

Thoughts, I'm leaning toward #1. I never go above #5 on the Smarty SR (90HP) and the stock pump performs just fine. Is replacing it with a good tool kit a "side of the road" job or am I kidding myself.

 

you could also do a walbro setup if you can find one. would be cost effective if you diy

then any quality car parts store will have a walbro pump on stock most of the time.
or just buy 2 pumps at first since they are 99 bucks or less.

most walbro pumps will last 100k plus at 45psi in a car.....at 20psi it should last a long long time.

 

Go with the Airdog 100. It will plug right up, very easy install, and get the better filtration to boot.

 

Thanks for the ideas. Found a great link on an airdog install.

I'm still leaning toward just carrying the spare OEM replacement pump. Why: $400+ for the airdog and I've got no spare (2 is 1 and 1 is none).

Still looking at the Walbro idea. Is there a specific Walbro pump number I can google?

 

i ran the holley blue on my 03 and 98.5. it cost about 200 parts and all. put on the frame next as close to the tank as possible

 

No one seems to like the idea of just keeping a stock pump on hand as a spare?
Are all these aftermarket pumps (Holley, Fass, Airdog, Walbro) that much more reliable? I'll pay for reliability/performance if someone quantifies how much more reliable/better performance I could expect.
My stock pump has gone over 100K, delivered the fuel and a spare is only 4 bolts to swam and $187. Am I being shortsighted?

 

some last some dont but if they where so great then they would still be on the trucks.

 

What about a Raptor fairly easy install and comes with a good warranty.

 

Decided to order an Air Dog 100.

I will keep the stock pump and all lines in place and unplug pwr supply. Then I can switch back, should the Air Dog ever go.

Seems like a pretty easy way to have a backup. Anyone see where this would cause any problems?

The disadvantage of a spare stock one is that they are hard to put in and they are a poor design.

If you run a Glacier setup with a Walbro pump you can change it out in minutes with another Walbro or with any cheap 12 volt pump from any parts store in minutes. I carry a cheap replacement that cost about $10.

On the '03 and '04 you don't have to get into the tank at all. The pumps are quiet and not some proprietary setup that will require a special order if you have trouble. Plus the Walbro is far cheaper.

If you want better filtration than stock you can always add a spin on 2 micron setup and easily get replacement cartriges.
