Read the quote I modified. ForemanES provided the info.
I don't have a fuel pressure guage, either. I have an old tire pressure gauge that I'm planning on using to test my fuel pressure. 10bands sent me three BB's to use for the FPR. If the holds tomorrow, I may get amitious and give it a try.

My local NAPA gives a 7% AAA discount so it is $40.30 after discount. I always forget to order backup filters online for cheap. Then I get everything tore apart (usually for the injector harness problem) and just pay the $40. I try to blow mine out with compressed air (inside out) every six months or so and replace once a year along with the fuel filter.

cobaum, if you are only replacing your fuel filter once a year, that ain't good. I guess depending on how much you drive. But, changing it also gives you the opportunity to check the health of a few things. 1. Your fuel tanks. Diesel is very suseptible to algae and you wouldn't know you had it until you change your fuel filter. If you get enough of it it will clog the fuel filter and who knows what else. 2. It's usually a good tell tale device if you are having leaky injector orings. But most of all, it's just healthy for your truck if you put alot of miles on it. I change mine every 10,000 miles, or every other oil change. But that's just my opinion.

Sure, you can measure it at the schrader valve on the Fuel Pressure Regulator with a tire gauge......I think. That's where you get your fuel pressure if you run a gauge. But I'm not 100% sure if you will see the difference there or not. I can't remember the exact fuel flow through the system. i.e. is that after the filter or not. Now that I think about it, I don't think it is. That's a good question. Now I'm wondering.....

I know it will be fine and work forever but the Excursion only needed a 2" piece and the filter just butts up against the stock intake tube and it lays in there perfectly. Point is, the tube on the later model is a little longer and I think has a little more bend in it. I think if you could get your hands on one from a junkyard or something it may work even better for the obs also.
As far as changing time, I got the idea from someone else on here to put the filter indicator in the end of the filter so I can watch it. I think its gonna be a pita to do every time I change the filter. I am planning on installing it in the tube itself so its done once and not with every new filter. Anybody see any problems with this idea?

Neal, you can actually fit the rubber intake tube on your wifes over the filter flange. That's the way most of the SD guys do it. I will tell you it's very snug, but it will go on. You may put some soapy water on it and take the clamp off all the way. But it WILL go on there, I promise. A piece of 4" exhaust is actually too small to clamp in the tube. Just FYI.

its not mandatory but thats what many guys do. Pull the cap, pull the filter, drain the bowl completely then reinstall the filter, fill with some diesel additive and replace cap. I usually do all the minus refill with additive. i usually just pour some fuel in there to help with the air getting to the injectors.
