I haven't done a compression test yet, but I'm sure from the poor cold starts (yes, I tested the gp's) and a couple other things that there is a bit of blow by happening. I want to do the water injection to get the carbon/gunk buildup off the rings so I can get a real compression reading before I start throwing a ton of effort and money at the rig. It not like this is my only means of transportation, but it is fun to drive and gets decent mileage.

As far as the lovecraft conversion goes, as near as I can tell, it amounts to:
1 auxiliary electric fuel pump
2 a heat exchanger that bolts in place of the stock fuel filter
3 the Davco 234+ which is just a heated housing version of Davco's water separator/filter. It seem to be good quality and replacement filters down to 2 micron are commonly available.

This version doesn't have that goldenrod housing with the washable bag filter. There might be some fuel routing changes, I'm not sure yet, but I see no reason any of it would be incompatible with a two tank system. I'll grant that using coolant as the ONLY source of fuel heat doesn't seem that smart (my temp gauge goes down to 60c on some long downhills around here). Trust me, I have been doing a LOT of reading.
