I have a question about my 1982 300SD 240K that's been converted to run SVO. Please respond especially if you're knowledgable in the veggie oil systems world. The symptom: The car has extremely poor acceleration - you have to floor it for about 4 to 5 seconds to get it to move from a dead stop. In the first half hour of driving though, once the car is actually moving, it does have some power. However, after things warm up a bit, it quickly starts to lose power, and when you come to a stop, the engine will stall. My mechanic noticed that the fuel pump in the trunk for the veggie tank was excessively hot, whereas it should only be getting warm to the touch. How likely is it that a stronger and more efficient fuel pump would solve the acceleration problem? Does it make sense that the car would progressively lose power if the pump was getting overheated / overworked? Also, it may be significant to note that i'm unable to switch the car back to diesel at this point, most likely because the solenoid switch is broken. So, it is starting and stopping on veggie at this point, which seems like it might be fine in the summer months. The previous owner was the one who did the conversion...
work that has recently been done by my mechanic (who doesn't understand veggie systems):
replaced timing chain removed diesel tank and tank filter and cleaned them cleaned diesel fuel lines spent a month and a half not doing too much at all with my car
