Hi,
I've had my 1987 300D in storage mode(ran in Diesel only, no SVO) for about 6 months. It ran fine on the 2-tank conversion with SV100 valves prior to now. I tried to run it and came to the conclusion(after checking the wiring) that both SV100 valves are sticking in the Diesel position. I get 20 Ohm on each coil and they draw about 0.65A at 14.2V when activited.
Has this happened to anyone?
Should I try disassembling them and cleaning them out? They are about 18 months old with only about 30gal of SVO run through them.
Any help is much appreciated.
-Kingsley.

Definitely yes.

Next time before put it to storage mode, suggest to empty the veggie system and put diesel in the
veggie tank and run in both veggie mode and diesel mode to completely purge/clean out out the
veggie oil from the fuel supply system.

That link describes how to dismantle and clean the sv-98 valves not the sv-100's. I've thought about cleaning my sv-100 valves but couldn't find any info. Anyone know where that info might be?

As described on the previous pages, the flow through the valve operates in a particular way. The flow of the valves are illustrated below. Though the SV98 is shown, the SV100 flows in exactly the same way
