I have a amsoil Bk21 on my truck with both the oil and oil filter caps from amsoil. My problem is, it is a major pain to change the oil filter b/c when I untwwist the oil filter cap the line gets all wrapped up and I end up haveing to disconnect the line. Is there some type of fitting i can get to solve this problem? The amsoil tech said bp-89 woudl work but looking at it I don't think it is right. I think I need some type of elbow fittting?
