Btw, my serial # is 1G300338
and their bulletin is saying 1A349420 and below . So I'm in the clear with the paint issue?

I wouldn't say yes or no until you do some more digging. The symptoms are saying one thing, now you need to do more forensics to rule things out.

Fixed
 

I fixed both issues today but have a new one because nothing is easy. So I don’t have the painted fuel coolers. I was getting too much fuel pressure. Almost 90 psi. I replaced the fuel cooler filters and the fuel regulator. Fuel pressure is normal now. Bounces around 40 T idle

The regulator had some crud on the white plastic piece so I’m not sure if that was the issue. I bought a regulator the other day just hoping it would be that.

for the starboard misfire. Ran the Rinda scanner and if found no codes. Checked each coil one by one with a spark gap tester and all looked fine. Just for the hell of it, i replaced a coil that I suspected was bad because I had a new one here. Took the boat out and no Misfire at high rpm any more. Not sure if ir was the coil or maybe me taking off spark plug wires for testing fixed something (like a loose spark plug wire)

now the bad news. When replacing that fuel Regulator it’s held on by 2 bolts. One of them snapped inside. I tried ez out and end up drilling it out so I can tap a new bolt in. Well. The tap broke off inside the hole now

I’m going to see if I can just take off that top part and then take it to a machine shop or jusr Buy a new top piece. Or a whole new fuel cooler. Ugghh

im still working on getting the tap out because I was pretty much there. I just went too far with cheap ass taps

so overall I’m pretty happy. The Rinda scanner works great!

Easy outs are carbide and that size are brittle. Take it to a machine shop with a TIG machine and they can fix

Glad you made progress! I had a feeling that your problem was ski high fuel pressure.

I found a new top for it for $140. I figured its probably better than a machine shop fix and around here they probably would want $200 anyway.

Yes, thanks for all of the help. Without this thread I wouldn't really have known what to do. Having an idea on where to start goes a long way! I do all of the work myself and learned a LOT this weekend. Even though I have the good gen 3 coolers, I did find some sludge under the fuel pumps sitting on the bottom. Not paint, just sludge. I'm wondering if this caused the clog in the regulator (assuming it was clogged). And now thinking I should check the other side.

Do you have plastic fuel tanks? I would want to find the source of the sludging.

metal tanks. But the boat is 25 years old. I had all fuel lines replaced because they were horrible.
It wasn't a lot of sludge, maybe a spoonful at the bottom under the fuel pumps. Maybe just crappy fuel, who knows.
