OK, when you say an added line pump, are you talking about just an electric inline fuel pump?
Yes.

Also, should the inline fuel pump be place on the diesel as well as the WVO tank?
One pump should do it, downstream from the switching valve. If you used two (or just one for WVO) you'd have to make sure it's not pumping when that tank is switched off.
However...It's my opinion that running an inline pump is a band-aid for other problems that should be fixed--except possibly for WVO. Based on what I've read, if you don't preheat your WVO, it's going to put a lot of strain on the injection pump even if you do have a line pump.

What pressure should this inline pump hold?
That one I'll have to pass on, since I don't recommend using a pump.

And, what the heck is CSD? And VE injector pumps? I keep seeing these in posts on this forum?
The CSD is the "Cold Start Device". The Isuzu CSD used springs to advance the timing for starts, and pump pressure against a piston to retard it back to normal timing. VW used a manually actuated Cold Start Device, which proved more dependable. When the Isuzu CSD seals wear out, it can cause the timing to fluctuate, producing erratic performance. I had this problem, and it took me YEARS to track it down. Removing the CSD fixed my problem. My fuel mileage went from about 29.9 mpg to 35 mpg (and occasionally up to 38) just by removing it.
The "VE" refers to a pump design that is owned by Bosch. Isuzu (or its supplier) licensed this technology and they manufacture it. VW also used it, as well as others.
