so i have this greasecar kit 2 tanks in my 84 300sd not sure if i have an air issue on the wvo side... but i notice when i run on wvo it runs okay, slow and wack... (i been driving for like 4 month) unknown if thats normal, when im on diesel runs much stronger,i changed the filter about 4 times like ave. once a month, then loss power because im assuming it get filter gets clog up.

i notice when im driving on wvo tank and for some reason when my diesel tank is empty car dies...its like im running on blend In order for me to run on wvo, i need diesel in my reg tank,its wired is that normal? what could be wrong with my system?

thanks
louis
