Re: couple o-ring questions 1) REPLACE IT!
2) Why gamble? How did you plan to size it, by eyeballing?
3) 12557075 (costs around $4.00)
4) No.
TIPS:
- Bolt the pickup to the pump BEFORE you bolt the pump to the block
- Make sure the you get the old o-ring out so you don't accidentally install both.

Re: couple o-ring questions Do not take chances here - a real PITA if you screw up!
Change to a new o-ring - $5 at my dealer... your dealer will have these in stock...
Follow JMX's instructions -
Also, replace the o-ring and bolt up the pick-up tube BEFORE you bolt the pump to the block - this prevents you from pinching the o-ring...this is especially important if you are going with a double roller timing chain...
place a rag between the pick-up tube and the pan so if you drop the pick up tube bolt it does not go into the bottom of the oil pan...
You can try two o-rings there should be plenty of space on the tube; I'm not sure if anyone has tried this yet, however...
