I have the exact same pump that I was going to build a complicated parallel system for.  Your pump is in-line - does it run all the time or just when priming?  Does your DD mechanical pump draw through it with no problems, or have you done away with the DD pump?

My bud did his with a T before the pump and after the pump which essentially created a cirle in the line.  He has the pump on one side of the circle and a valve on the other.  when he wants to prime he closes the valve and starts the pump.  When it is ready he opens the valve and turns off the pump.

Van's setup does not affect the DD pump you can make a priming system as simple as you want or as complected as you wish most of those pumps are flow through.
I have use the one pump no valves for the past 20 years without a problem I just used it to prime with and turn it off,I don't recommend using the little filter in line fwiw I never fill the filters I turn the pump on for 4 or 5 minutes hit the starter button off you go lol

good luck

Brian, I still have the DD pump (new) which I replaced once I finally got our bus home, But did as Clifford suggested, I usually leave it off, but have on the rare occasion left it on by mistake with no ill effects in performance. Please every one, make no mistake, not my wish to ever bend anyones arm to do it a certain way... just my way!  Grin

Btw, Clifford. Just for the record, I was joking when I told Van that it wouldn't work. That was very much tongue in cheek. I really like that idea, and would do it to ours, if I needed too. We have the factory installed priming pump on there, now, that we use.

I have the garden sprayer setup just for an emergency.  An inline pump seems like a good way to go if it has enough flow-thru.  I once did it to a motorhome, but the pump did not have decent flow-thru, so I had to rig a bypass for it.  My last bus had an electric pump at the fuel tank that was on full time.  I don't even remember if there was a mechanical fuel pump at the engine.

Hey Van if they don't want the 24V pump for exchange an ya get "stuck" with it. You can throw it my way! LOL I'm building a utility trailer set up with a fuel tank and 24 battery system so when I do service calls I can fuel/jump straight from the trailer still gathering bits and pieces.

Lin, here's the pix I took this morning

 I got it thru CarQuest here in B.C.
  Bk,I'll let ya know, I haven't gotten back to the parts counter yet to see if they have the 12V version yet, but if they do, you are more than welcome to this one Wink. Oh there is a set of #'s on the flip side of the pump I'll try and get posted, so others interested can research them Wink

I have three of the pumps used by the mysterious Van and Clifford - two 24 volt and one 12 volt models.  they are available here at Princess Auto - http://www.princessauto.com/all-seasons/farm/transfer-pumps/12vdc/8270100-24v-diesel-fuel-pump
so you can see what it looks like.  I will experiment to see if it can be left in line with the DD pump as Clifford and Van's can but it sure looks the same from the outside.

I use the AirTex diesel pump forgot the exact number but think it is E 3073 or there about cost under 50 bucks most places ,fwiw Bosch makes a inline that will run the engine plenty of fuel supply at 70 psi I carried one for years waiting for the DD pump to fail never happen lol  

good luck

That sure looks the same Brian, although they don't give any other specs, they are most likely manufactured by the same folks. here are the numbers on the flip side of my pump.

I'll go to the shop in the AM and see if there are cross refrence digits for it.

All I have ever done is fill both filters and crank. Fill again if necessary with a little funnel through a little hole in the top of the filters.

When starting after an overhaul, fill the oil cavity for the turbo, crank for a minute, then open the governor and let er start.
