bad gas!!
 
I unfortunately bought bad gas from a marina just a week ago....what is the easiest way to pump it out....I tried the old fashion way through the gas inlet but there must be a screen at the bottom..i have 1989 Tristar 190....I ran like a champ not its dead in the water...will I need to change plug too!!!??

plug or plugs?

plugs...and they are hard to get at too!!

I would run it with some fresh gas and seafoam.. should be okay.

Haven't had to do this my self, but if you got a manual pump you could pump (like an oil pump). You can access the tank through the floor access next to drivers seat. You will have to disconnect and take out the sending unit, but plenty of room to stick a hose in.

Also, drain the fuel out the fuel/water separator bowl to get as much out as possible and where the other fuel filter is, open and drain the bowl.

If you're talking about spark plugs, no you won't have to change them, however, you will have to change the filter in the tank as well as the in line filter. The fuel pump on that is not in the tank, is it? If not there may be a screen in inlet of the pump. Are you sure that's what the problem is? If it's bad gas it will run crappy, but it usually still runs. Have you checked to make sure the pump is working? I would remove the tank completely and dump it out, and replace the screen in the tank.

I would save some of the bad gas in a clean glass jar. Have you talked to the marina? Any idea what the contamination was?

Been there done this man, had a half tank of gas and the seal around the fuel pickup and the bildge pump went out. the cover blew off, we got a ton of rain and a TON of water got in my tank.

Knew the gas was bad by getting a 5 gallon can and filling it up with new gas and just putting the draw tube directly into the can and it ran like a champ. ( i liked this way because this proved it was 100% the gas and nothing else, no guess work)

Now how i fixed it:
1.) couldnt find an electric pump cabable of handling gas so i got a manual hand pump and cranked away at it for about an hour pumping it all into a bunch of 5 gallon cans so i could dispose of it later.

2.) replaced the fuel filter on the line and for me the seal on the fuel pickup.

3.) replaced the spark plugs because heck it was already broken down i might as well, and they are not hard at all to get to. took all of 5 mins to change all 8.
