95 speedster no spark on port

No there not grey they are the marine rated a-1 that has almost 1/4" wall thickness but there kinda hard and not bendy like the smaller wall automotive. I'm worried that they won't seal good or am I looking to much into it

The factory grey lines made by Tempo are junk b/c the elastomer corrodes internally and will plug your carburetors. Yes, this stuff is USCG rated but it's rather stiff to begin with (marine fuel line A1 USCG is heavier wall than automotive) and most get stiffer with age.

Boat fuel lines were never Grey Tempo lines due to different USCG requirements for boats as compared to PWCs.

So I should not worry about changing them out then.

Yep, come to think of it I guess the earlier Seadoo boats weren't rigged with Tempo fuel line. The Tempo fuel line was USCG A1 rated and was used on the 951 boats and many other boats besides Seadoo.

We were rigging the outboard boats at our yard using Tempo fuel line long before we discovered the problems.

Well, the Tempo stuff was horrible stuff and would plug the carbs. It's important there are no leaks b/c if the fuel pump is sucking air you'll experience fuel starvation issues and this isn't good especially in the case of 2-strokes, good way to roast a piston.

So it's your judgement call based on what you see. It's always a good idea to start off with a leak-free fuel system and if the fuel lines are decomposing the debris from the fuel lines can plug your carburetors.

At least pressure leak check backward from the fuel pump to the tank barb and make sure there are no leaks, 5~10psi is an appropriate pressure for discovering leaks.

Then I always like to draw some fuel from the tank up through the system as a flow and debris check. Sometimes I use a hand pump or an electric pump for this to confirm good flow If you aren't able to freely pump a good amount of fuel or there's a good deal of debris being caught in your temporary filter, now's the best time to discover these problems.
