One concern may be pickup too close to the pan? Recommendation is 3/8" or so, what is funny is the manual say to make sure pickup touches pan???? It is not, but clearance may be low. Can a pu too close to pan really do his. I hate to have to drop the pan, but seems odd to me since pickup design has a relieve so that even if on the pan, it should not inhibit flow to cause a loss of pressure?
I was told years ago that the "touching" recommendation was to prevent the pickup from getting into a harmonic induced vibration and breaking at the threads. I have only personally seen this happen once on a '66 Hemi Coronet with a deeper pan that the pickup failed in this manner.
