Fuel Filter Change Frequency?
How often do you guys change your fuel filter? My fuel pressure gauge started doing weird things a few days ago,
If you want to know what it did: going to 9 psi and then popping back to 15 if I goosed it. Then Friday, it dropped to 3 psi and wouldn't come back up. I cut the truck off for a minute and restarted and it went back to 15, then in a few minutes it dropped to 9,, but if I gave it more fuel it would jump back up to 15, then a few minutes later it dropped to 3 again and would not come back up. Last time I lost fuel pressure, but not sporaticaly liek this, it was the filter. I gained 6 psi by changing the filter.
I changed the filter and cannot get it to drop from 15 at an idle, no lower than 12 cruising.
Anyway, I only got 7,900 miles out of this filter. I usually get fuel at the same place, and have never gotten any water in the fuel from them.
Thanks,
Chris

Every August and I have 143000 miles in five years.
I did find that the NAPA filters appear to flow better. It seems like the ports are bigger or something. The stock filters don't seem like they have holes big enough to flow right. Just my opinion though.

I change mine in my chevy 6.2 at the same time as oil and filter, every 3k miles. Never had a problem with injectors or pumps in 170k mi. For the few bucks extra each oil change, I sleep alot better. Am also going to do the same on the new Ram.

Sorry, forgot to specifiy, my filters are Napa also.
For those of you familiar with the area, I usually get fuel at East Coast.
I'm just thinking this is a short time for a fuel filter, and if it is normal, other members should know, especially if they don't have an FP gauge, so they aren't working the LP harder than necessary or cooking their VP until the change.

It's my pot and I'll stir it if I want to. If you're not careful, I'll stir your's as well!
Stamey, if you always get your fuel at the same place chances are that it is not bad fuel, but hey, it is not impossible that a tanker dropped a bad load in and you just happened to pick up some of it. My guess is that it is a bad batch or two of fuel and that has caused your filter to clog up quickly. Proves it is working as it should.
Ask your supplier when last they changed the fuel filter on the pump and see if the date has any relation to when you had the problem.

Before I went to FASS I changed it at 15,000 most of the time it did not need it. A couple of times it went out in a much shorter time. N ow and then you will get some dirty fuel.
