Not having trouble, just happened to take a closer look at the VP44 today and noticed that it looks like it may have been replaced. I say this because I know how aluminum will oxidize over time (truck is an '01) and this looks way better than I would expect for an almost 20 year old piece of aluminum to look. The fittings attached to the pump look fairly new also. Just wanted some other opinions so please see the 2 pics I took. It actually looks better in person. 

 

Yeah they very good for sure, but I like having a prefilter set up on the system. I think it's important from what I have read in the past anyway. You can't have a prefilter on the mechanical pumps if I'm not mistaken.

An Air Dog goes out and you get a free one sent to you. It's a good deal that way. Rich guys on here go for the mechanical pumps they the best, 

I’m far from Rich and have a mechanical pump, when all said and done it’s about the same price as the air dog or fass set up,

The mechanical uses a pre-strainer, 26 micron I believe 

If you do want the prefilters like an the AD and FASS thats when the mechanical gets expensive unless you have a cheap source for the filter heads.

Please explain, but please don't bauck at me my wife does that enough.

The pump is no more expensive but if you want filters that the AD and fass come with you have to buy filter heads to screw them onto. They were 150 to 200 bucks last time I looked. Been a while though.

Here's a photo of my injection pump.   It is a replacement remanufactured pump purchased from @dieselautopower and installed 8/25/17 by me and @Mopar1973Man in Riggins, ID.  The truck had about 97,000 MI on it.  Some rebuilders use tape/label, some use paint and some use both.  You can see the yellow anti-tampering paint on the screw head like yours has on it.  Yes, I'm still using banjo fittings from the filter to the pump.

 

 

  

So @IBMobile, you think it could have possibly been replaced? 

 I've been getting mixed opinions, it's not a huge deal either way. If it has been replaced I don't believe it was that long ago which tells me it will last that much longer is all. A VP is a pretty big expense so if it had been replaced it more of a piece of mind.

Your pump has been replaced.   There should be a tattle tale tape saying warranty void if removed on the connector where I circled.   Yours is missing.  your warranty is void.

 

 

I know my brother's 2001 had it.

If it has been replace then I am somewhat relieved. That's an expense I didn't want to deal with anytime soon. Lol

 I have begun a 2cycle oil regiment when I fuel up to help prolong the life. I want to go to bigger lines with a pressure gauge before long as well to keep an eye on things.

I had this before I put a BD cover on and I had the void sticker, which I guess could of stayed on from last time po changed the pump.  

I too wonder about my VP44. I'm assuming mine is the original pump, I don't see any yellow tamper indicator paint on any of the fasteners, although the yellow void sticker is there but ripped. My truck had around 211k when I purchased it in 2013. The first thing I did was install a fuel boss mech fuel pump and big line kit.  Now I'm at 232k, no pump issues so far.  @Mopar1973Man mentioned expect Vp44's to last 250k average. So I guess that makes me a bit nervous if my truck has the original Vp44

 

Regardless I am at least certain that it's the correct VP44 for my truck HO 245 HP / 6 speed.

The numbers on my VP44  pump end in 28, which means it's a multiple of 7 (14, 21 or 28) which is specific for the HO 245 HP.  Which transmission do you have? If you have a chance update your truck details in your signature.  Maybe check out this video to at least verify that you have the correct pump for your engine/trans. If it's not the correct pump for your engine / trans then at least you have a tell tail sign right there that it may have been changed.

 

I will have to update my sig again. I tried linking it to my garage like some do here to give more detail but I can't figure it out. 

 My truck is a 2001 3500 qcdrw SO with nv4500 5 speed
