60x fuel system
New to me 87 190D 2.5 . How does fuel system work? Is it similar to 61x like on 240D?
Interest is setting up for 2 tank D2 and WVO.

There is a fuel preheater in the system. Otherwise it's pretty similar to the 61x.
The flow is tank -> prefilter-> preheater valve -> preheater (if the thermostat in the valve is cold, otherwise it's bypassed in the preheater valve -> preheater valve -> lift pump -> main filter -> IP -> injectors -> injector return/main filter bleed/IP return -> tank. Also note that there is no hand primer on the 60x IPs. If you get air in the system you will have to crank like crazy to re-prime.

Thanks.
Hmm. I wonder if a primer pump could be added someplace. Under the manifold tho.

Thanks, could anyone point me to a schematic?
Sounds like similar changes would be made to greasing a 61x. Route secondary filter to suction sided of lift pump, output to IP, and block the bridge between the injector overflow and secondary filter. 2X 3 port valves to switch between D2, VO and flush.

So, slightly more complex than brick simple, but still able to fit on one or two napkins. Maybe a placemat instead. I love places that have the paper placemats for doodling and such.
