Showing old paint comes off with razor blade

Wow. I went back in thread you have done a lot. It’s summer Most folks are busy playing

Here's some help.   The top two rows are not my boat so I can't attest to 100% original, but the front seats are the right style (unsure about the piping) and sure looks nice..   The lower row is my interior (sad I know).   I dont have rips, so going to give the SEM treatment a go... for a season at least. Anyone used that product?     https://www.youtube.com/watch?v=XzlJac7yFOg.    Reupholstery & re-carpet down the line once mechanical is situated.

John,
Why the electric pump? Put the mechanical back on the engine.

If I do go to the mechanical type is it the same type as the automotive or something special?

While I'm with Pete that there's no reason to not be using a mechanical fuel pump, you still can do some simple troubleshooting on the electric to see why it was working fine and now isn't working. Is there power to it? Can you feel it running? If so, make sure you have fuel flowing to it, don't have a gummed up anti-siphon valve or bad fuel pickup in the tank. If it isn't running see if you have power to the pump and if not go back in the wiring to find out the problem.

How about the original fuel line from the pump to the carb? It's most likely steel with inverted flare ends.

This the fuel pump

I took it apart but the auto store doesn't carry a rebuild kit. Gonna check Skidm.

Wow thanks will bookmark

Quick question on battery cable. Will 2 ga. be ok for a 6-7' positive and 5-6' negative??

PO had 6 ga and it melted, and the #1 boat has 1 ga but I can only find 2 ga

Didn't see your post before I posted mine. 6 gauge is nuts. I was able to buy some heavy gauge battery cable at an auto supply house, the kind that has truck parts and batteries. I used some 1/0 in a diesel pickup, I'm sure they had 1 gauge as well.

Any Heavy Duty Truck shop keeps bulk heavy battery cable in stock and can cut to length for you.   By Heavy Duty I mean, Kenworth, Peterbilt or Freightliner not GM Ford or Dodge.
They sell the connectors that bolt to this size cable also.
