Damn I’d love to have you take a look at my fuel system in my boat. I’ve had a few situations where i got air in the rails as well one pump over heating, even tho i hopefully straightened part of it out by rewiring and removing a butt splice with some corrosion as well.
I do the launch and retrieve myself, and when in Havasu prefer the Marina for the reasons of easy ramp, back to the dock tie off run to truck park and back to boat for the day then reverse.
All this, except the 05 has the cool fuel box, three 10mm bolts (they won’t pull all the way out they have a lock on them) then pull the little two finger tab to lift it out. There’s a small filter inside the plastic can that comes out, however there’s also a small flat prefilter down below...
