I have a squeegee for that.

 

I'm leaning toward some other problem, not the pre-pump filter. I am running a CAT 1-micron pre-pump filter for a few years without a glitch. I run a 2-micron filter in my 8V92RA without a glitch and that engine uses about 12 gallons an hour .

 

Alright, I'm fairly confident after getting my truck back from the steering column shortage (new bearings & shift lever) that the filter swap didn't make really any difference.

I decided to do an oil change, which absolutely made a difference. This was surprising to me (keep in mind, I've only been a PSD owner since October '13), as I was only at the 4500 mile mark for the winter change to Mobile 1 5w40 (turbo diesel oil). I must say, I did notice a "boost" in power when I originally changed the oil at the beginning of this winter, so maybe the truck was just ready for some fresh oil - just not sure!?!

Went with Mobile Delvac 1300 Super (15w40) this time rather than Rotella, as Wal-Mart offers Delvac and Delo for $12.50 a gal now - woohoo! Anyhow, once I get gauges, I'll be able to provide factual feedback, as now I'm just going off my fuzzy memory.

Thanks again, all!

 

I would suggest that you just might have a very tired OEM pump. I've been running the BF1212 for a while now. Admittedly, though, I also installed a Carter "lift" pump between the BF1212 and the stock pump just to make sure that the more "mature" OEM pump did not have to carry the full load of the pressure drop across the BF1212. My Carter pump lasted around 75K miles, IIRC.

Given, though, that I work with hydraulic pumping systems on a much larger scale. I am sensitive to the issue of excess pressure drop on the suction side of a pump, so my plans are to switch over to the exact same thing which Tugly is now running. However, with my plans to sell my current 2WD this summer and replace it with a 4WD PSD, I am going to just hold onto the new setup and put it on the "new to me" truck when I get it this summer.

As for the "simple inline filters" that a lot of guys run, I have had one for about 4 years on my Excursion and will not ever do that again. At least three times, I've had trash plug up that little thing with less than a year's run time, and that's only about 8-9K miles between filter changes. I just do NOT like the small amount of filtration surface area they offer, and would rather have much more surface area to be able to handle the trash that I obviously pick up sometimes in that vehicle (I always fill up my truck at a different station than my wife because we travel in opposite directions).

 

I appreciate the reply! Here's the thing, it's a brand new OEM rail pump, as my other one didn't make it a mile down the road after the hutch + BF1212 we're installed by my local shop. Anyhow, I do like the idea of the "see through" filters, as this gives you an excellent visual of the amount of crap that was caught + the possible culprit.

 

I was running one of the small inline filters for my prepump and this winter I had all kinds of gelling problems even with three times the normal amount of Powerservice additive. The small filter plugged up with gell in a matter of minutes below 0*. As said above the smaller filters plug up way too quickly. I wound up getting a Racor heated filter and have had no problems since, and I stopped using additive. -15* and no gelling without any additive. Here is a pic of my filter.

 

Just one more observation I've made with my three PSD's. My son had his pickup foot (inside the tank) disintegrate this fall and all the pieces caused extreme line pluggage in the hard tubing at the top of the tank. His pump was (no doubt) a tired one with nearly 315K miles, but the additional strain of the plugged line lead tossed it over the edge to a complete pump death. Once we cleaned out all the lines and then replaced the pump, including a BF1212-style canister (Wix brand equivalent) ahead of the new pump which was not there before this fiasco, his truck has run well ever since.

 

When doing the hutch, we apparently caught it in time (per my tech), but was close to doing as you described. Got a new one on there now!

To clarify, after loading her up with new Delvac 1300 (15w40) yesterday, she's got pep in her step now that I was originally complaining about. I just don't understand how the Mobile 1 turbo diesel (5w40) was causing minor hesitation at the 4,500(k) mark, and I didn't get a sample for analysis, so my apologies! I do have a kit on the way, and will be sending the next change off to Blackstone.

I'm fairly certain I won't have a gelling issue since I live in Austin (TX), but do visit my dad in Kansas City during the holidays (thxgiving & xmas), so I do carry an anti-gel additive for then

 

I'll be darned. Another member from Austin TX! My OBS will start throwing a fit when the oil gets over around 3000-3500 miles on it so I'm not really surprised that yours woke up a little with an oil change.

 

Question... was your run on Mobil 1 5w40 the first time you've used that oil?

If so, then it could easily be that the detergent package was beginning to break down internal sludge deposits and giving your IPR some fits, and an oil change would have flushed some of that out and allowed your IPR to perform better. If that IS the case, then chaning oil with another round of Mobil 1 would have given the same results.

It typically takes a good 3 complete oil changes for your engine internals to get completely swapped over to a new oil.

 

I run a napa 3405 filter and havent had a problem, other than when i open the water drain wile its running i only get a few drips witch i thought was weird

 

And for oil i run rotella t5 10w30 i have 260,000 miles and thought the original injectors would like the thinner oil and i live in ny so its cold out now, haven't had any problems yet

 

If you open the drain while the truck is running I would assume it will suck air in, not let anything out, because the fuel pump is sucking through the filter. I was told to never open the drain while the truck is running.

 

The engine should have had a stumble or something
