I had a sudden change in performance after 1 year running on SVO. After switching tanks from SVO to diesel, the truck started running really badly, at one point I couldn't get it to start. I thought it might be air in the fuel lines so I checked the SVO conversion and fittings and put in another fuel pump. Now the trunk starts and idles fine but has no top in power. Any thoughts?
Sounds like fuel starvation to me, something in your fuel supply system got plugged, especially if this happened all of a sudden, injectors would more likely become fouled over a much longer time.

I'm having same problems , what pump did you replace lifter pump or main fuel pump? Thanks Jerry B.
I would replace the OEM fuel filter (at the front of the engine) , which is likely shared by both the vo and diesel systems.
