$30 would be a terrific buy. The capacity is 8 quarts so for our diesels it is a push,
I used the other day to change the oil in the 1987 300TD and I pulled out a little over 8 quarts out of the engine and I saw some oil came out of the pump handle. At this point, I do not know if the pump seal has failed or it was due to over capacity.
Will try in water to see if it is damaged.
