I pulled the pan off my 292 just to check things out while it is in between cars. I thought it had sucked some air a time or two and sure enough, there was a clean 1/2" between the pickup and the pan bottom. This is a Nova pan, bumped out at the back to clear the #6 counterweights.

So, I just gave the pump tube a tug, to see how much I could pull it down. It started to rotate in the pump! Must not have been very tight all these years in the other car. \:D

I can try to hammer it in to see if it tightens up but wondered, short of tack welding, are some JB weld or solder good options to make sure the tube stays in place? Other ideas?
