Rebuilding Cool Fuel Module Gen 2- what parts?
Planning for removing the Cool Fuel Module Gen 2 to replace the cooler tube itself due to leaking water and general corrosion. I am wondering what parts are going to be corroded, or in need of replacement during the process of disconnecting the fuel lines and associated fittings for cooler replacement. I already have Ref # 8 OEM copper cooler that was found as an unused part from a cooler/pump kit. Link to parts diagram-

What Column 1 Ref # should I order to complete this repair? No reason to suspect that the pump is bad or the regulator needs replaced at this time, boat has 200 hours on it and everything is working fine, just the cooler has some corrosion and is leaking water externally but cannot see where due to limited access.
So far I am thinking part Ref # 6, 7 and 5 , 4 the elbow could be crusty?
Seal 25.
Without knowing any different regulator and lines/hoses should be able to be transferred directly so part 17 and 18 should not be needed or will I need to remove the regulator from the lines? Part 14 and 15, the filter and seal. I don't know what the filter is made or if it would be crushed and part of the seal so may as well order one of those. I have some Heat Sink Compound though that is not listed as a part.
4 5 6 7 (8) 14 15 17 18 full list for repair?
Anything else I may need to order? I plan on disconnecting the fuel lines at the filter head and then the connectors and dragging the whole mess out at once. There is limited access while in the boat, would not be able to make connections or disconnects at the Fuel Module while in the boat. Any hints or things to watch out for while doing this? I have service manual #31 for torque and other info.
