Moving the pick-up is what it looks like:
1. new tube enters the pump body straight on (no bend right at the entry)
2. same tube ID or larger as original
3. clears counterweights, rod path etc.
4. positive attachment for the pick-up head to the block, main cap, pan wall, etc. if possible (don't "hang" it on the pump unless you have to)
5. use the original pick-up head and screen, or larger
6. pick-up bottom is 1/4" to 3/8" above the pan floor
