I am not the original owner.  I didn't install the FASS HD.  The pickup looks stock, and I can't see a draw straw.  I am thinking of putting one in as I need to replace my fuel level sending unit anyway. 

Is there any way to tell?  After looking through google images and on Rockauto for pictures, I really couldn't tell any big difference.  All the photos I see have a 4 prong plug.  The only big difference is that some of the in tank pumps have a squat hockey puck looking filter on the top of the pickup. 

Is the block mounted pump still there and plugged into the wiring harness?  When mine was installed there was a relay on the firewall that was added for the pump on the driver's side and the oe pump was gone. Here is a picture of mine. I think ME posted a picture of his that is a little different than mine. Another way to tell is bump the starter and listen for it. 

No block pump.  Just a relay up there for the FASS... Not OEM wiring either.  

Here is what mine looks like.  Similar, but not the same.  Hard to see, but I don't have the big thing on the left that you have, and the plug is not parallel with the fuel line fittings like in your picture.  The right side is mostly the same.  

I am trying to decide what draw straw to order.  It seems like different kits for the in tank vs standard pump types.  I am just going to order the cheaper old school one.  I like simple.

That's what I would do.  Without pulling the canister there is no way to really know what someone else before did or did not do

My fuel basket is not the oe one for sure. It was the only part I got to use of the almost $1k I gave Dodge for it. IIQRC the black thing is the vent. 

I need to change the fuel sender anyway.  I ordered a draw straw from Vulcan.  $35 shipped.  not bad.  

I am making a list of "To Do" items to get the truck "done" for the next year and the move back to Colorado.  I have gotten quite a bit done, but I am not 100% satisfied.  I was planning on tackling most of this this week, but I have been stricken with some form of Arkansas head cold.  The list has doubled, which is what happens when I have physical downtime... I catch up on my planning.  Last time I had a cold I read up on alternators and determined what my problem was, hence that article.  

Long story short, this truck getting cheaper to maintain, as I am finally getting back to "normal maintenance items" and less immediate or performance modifications.

I feel your pain. I often wonder what I would do with all my free time if I didn't drive old clunkers. 

Ya, but it's always nice to have a project. If I didn't have a Dodge in the garage, there would be something else. The best thing with a Cummins is that the power adders can also net better fuel economy, that's awesome!
