I thought of going there also but, I did like being able to bolt on a pan from Cummins that looked just like what I would have spent a couple days building. I thought of bob'in off the sump, but wasnt happy with the amount of oil that was left. This new pan accually holds more now than the stocker so it should aid some in cooling as well. 13qt. low level and 15qt. high level, that shold be 4 gallons with a filter -if at the full mark-. Why are you having clearance issues in a truck again?
