2008 Challenger 180 fuel, oil, and fault codes

[RELENTLESS]

Ok so I have a 2008 Challenger 180. Just got the candoopro because I bought a new cluster. Now that I did that myself with a few other things. I got a P0520 CODE Which shows oil pressure switch so after some googling I boat the item below on amazon . Also when driving I get a popping sound do to running lean. My seadoo guy that had it in the shop said the fuel pump and regulator needs to be changed. So I figured I'd do that myself too, which I ordered parts on amazon below to see. Anything I should know first before digging in to it. How easy or difficult is it to do myself. Any help or guidance would be greatly appreciated
Thank you

I can't tell you about the fuel stuff but I just did my oil pressure sensor. If you are a little bit of a finger contortionist you can do it without taking anything else off. You will need a deep 21mm socket with about a 6 inch extension to come in from under the throttle body after you remove the connector. That is the part that takes some finger work. My sensor failed from oil leaking through it which got oil on the connector, so I cleaned it thoroughly with electrical contact cleaner spray before reconnecting.

The most important thing I have learned working on this boat is you need to be scrupulously careful about not dropping things that will end up under the engine and very hard to retrieve. Resist the urge to set tools or parts down somewhere convenient but where they will end up falling in. I have even attached a tether to tools when I am reaching and working them in tight quarters with just fingertips in case they slip out of my hand.

Lol thank you for your help. May be a dumb question but will it leak oil while changing this part?

No, nothing more than a drop or two. Also, note the threads are tapered and there is no seating surface so don't over-tighten.

Thank you... Got all my parts gonna get in to it this week. Also noticed I'm about a quart of oil too much.. Strange since I actually had the oil change done at a shop. But when I check it's above the to lines on the dip stick. Also had to reorder the pump.. This is the correct one here
