I'm right in the middle of putting a deeper B&M pan on my 700 right now and am wondering if I need to use the longer filter spring that came with it. This is the first time I have pulled the pan since I have owned this and it does not have the factory support spring. When I pulled out the new filter I bought it said that the filter design had been updated and that the spring was no longer needed and that if mine had it to discard it. So I'm kind of at a loss as what to do since the filter will be lower now with the pickup extension for the deeper pan. Any ideas?
