    1991 glastron 1900 hull

    When I said I put in a new floor it wasn't the full story. I have a thread with more pictures covering the project. But I went to the hull, spliced in new stringers and redid the motor mounts. The "crack" seams to be about 1/2 into the fiberglass in between layers (air bubble during...

    1991 carburated 4.3 fuel pump output.

    That 35 gallon tank would have to pull out of the bottom to have enough head pressure to seat that ball against the spring and stop flow.... and then the boat wouldn't run at all. My best guess is if the tank had a straight through fitting and the fuel system expressed a leak it would alow fuel...

    1991 carburated 4.3 fuel pump output.

    So my back ground is heavy equipment and over the road trucks so this is my best guess on how this goes. We are both right. The anti siphon works both ways. The spring is strong enough to close if there is a leak but will open when it is exposed to vacuum from the fuel pump. It also closes to...

    1991 carburated 4.3 fuel pump output.

    Well .... no. The spring pushes the ball against the seat to stop fuel from flowing back into the tank causing the fuel system to loose prime.

    1991 glastron 1900 hull

    So this is a real downer. After putting a floor in the boat, a project that took 4 years due to life events, I got it put together troubleshooting the fuel system not wanting to let the boat go zoom... just to come home to water leaking from around the middle of the boat below the water line...

    1991 Glastron 1900 floor.

    After several trips to the lake, I got the fuel issue figured out. Had this build up almost all the way around the sealing surface of the fuel/water separator filter and I think there was an issue with the anti siphon valve. Had it out yesterday and it ran perfectly. ... Its been a long road...

    1991 carburated 4.3 fuel pump output.

    Took the boat out yesterday and it ripped! No issues. I am going to put a anti siphon valve in the line from the tank to the filter because getting to the fitting at the tank is such a chore.

    1991 carburated 4.3 fuel pump output.

    So its been a couple trips to the lake and still no smoking gun. I did hook up the 12volt fuel pump in line with the mechanical fuel pump and the boat would run for a longer period of time once on step.... some times. Came back got access to the fuel lines at the tank all clamps were tight...

    1991 carburated 4.3 fuel pump output.

    I tore down and cleaned the carb. Had issues on the first start up, the needle and seat that came it the kit did not want to seal. So some premium went into the crankcase I'm afraid. Put the old set back in and didn't have a a problem after that. I don't have the manual so I did all my adjusting...

    1991 carburated 4.3 fuel pump output.

    Is there a specific marine Carter fuel pump you recommend? I read about how you don't use a automotive fuel pump in place of a marine one because of vapors in the engine bay.

    1991 Glastron 1900 floor.

    Hello, back in 2017 my son found a soft spot in the floor of the Glastron 1900 we had bought 3 years before. So in the spring of 2018 I took out the seats and ripped up the carpet and found lots of rot. So pulled up the decking and found that someone had already been into the floor. Found the...

    1991 carburated 4.3 fuel pump output.

    Hello, I am new on here. I did a search and found lots of questions regarding fuel pressure but none about fuel volume. I have a 1991 glastron 1900 that after 4 years of working on the floor finally put back in the water. It started and idled alright in the driveway but when I took it to the...
