Is 4000 miles to short a life for fuel filter?

[VolCTD]

I actually already know that 4000 miles is to short a life for a fuel filter but help me out here. I drove 500 miles to Myrtle Beach week before last and the truck pulled great the whole way. I get to the campground and unhitch and park the truck, next time I go out to start it it idles like crap. Shaking and surging, even dies once, so I figure it's the air or fuel filter so I change the air the next day but no help. Next it's the fuel filter and it helps a lot but not completely. The next day I decide to pull the new filter back out and check for dirt in the canister. Sure enough there is dirt in the bottom of the fuel bowl so I take a rag and clean that all up nice and shiny. It still idles a little rough once I got home until I bought a 1/2 tank of diesel from a trusted source and added Power Service to it. Now it runs fine.



Now to the reason I'm even posting this. Should I be looking at adding a secondary fuel/water separator filter system? Do you think there could a build up of dirt in the fuel tank that needs to cleaned out? Since I know 4000 miles is way to short for a filter there must dirt getting into the system from somewhere.



Any ideas????

One really bad batch of fuel can muck up a filter pretty quick!

jjdiesel, yeah that's what I've started looking at was their separator combo unit. Do you have one and does it make a big difference?

Scooby, that's why I hate buying fuel on trips. you have a good source around home but when you're out it's a crap shoot. That's why I'm wondering if a secondary filter system wouldn't be a good idea?

The stuff GDP sells is great. I have their 2 mic setup underhood with a Cat filter, and my own homebrew extra f/w sep under the cab...

Can have too clean a fuel at 2xxxx psi

I saw your install photos from one of the other Cummins site, real nice setup. I'll have to put both of mine underneath since I have the APPS under my horn. Did you keep the OEM filter setup intact or have you removed it completely? I noticed that GDP sells a pass through to remove the OE filter but didn't know if it was worth doing. What filters besides the Fleetguard fit on the GDP setup?

I am continuing to use the original 10mu fuel filters in front of the 2mu GDP filter because I 'believe' the 10mu is a better water separator than the 7mu filter. Change the large 2mu filters every 3rd regular filter change.

4000 miles, try 90 miles

I got ahold of a bad batch this summer and was only getting 90 miles per fuel filter. Went thru 9 of 'em before all was well again. They were so clogged, you couldn't blow air or fluid thru them. (i tested all 9 of them).
