good evening,
i have a 1990 corolla with a 1c diesel idi and a bosch ve type rotary pump. i run wmo at 70/30 wmo rug. i filter down to 1 micron with a sock. i have a two tank setup with 2 3 way ball valves. when i am diesel, i dont get much engine hesitation. when i am on waste motor oil, i get a certain engine hesitation and the engine turns off at idle. i already upped the idle speed and it hasnt changed. its like if i am on.waste motor oil going at 30 mph and suddenly brake, thevm vehicle wont maintain idle and it will turn off. on diesel it will maintain idle after sudden deacceleration.
also when starting on waste motor oil i notice i have to push the accelerator pedal all the qay in when i crank the engine to get it to atart quick, while when i start on diesel i dont have to push the gas pedal in so much.
i think the lift pump is weak on the ip.
perhaps a 12 volt carter 4061 electric inline fuel pump will help with starting and mainting idle, that or replacing the lift pump on the ip. the mechanic recommended an ip guy who tried to fix the pump but said it needed a good cleaning. another mechanic said also to have an ip guy clean the pump. this ip guy recommended to replace the lift pump on the ip. the ip still had the fuel mixture screw safety on it so i would assume that means this pump has not been opened since new 33 years ago. at the least i am looking at a pump rebuild with new lift pump for the ip. does this sound par for the coursw? any suggestions
cheers
