Internal tank
 

Here we go ;D
Before I purchased the boat this year, it sat for at least 1 year. The boat was winterized but has about ¼ tank of old fuel still in the tanks (I am guessing on the ¼ tank as when the boat is stationary the fuel gage reads empty, but when it is running and we are moving it reads about ¼ tank)
Before I purchased the boat it did start right up from the internal/old gas. I am currently running on an external tank and everything is running beautifully (knock on wood, fiberglass, grab a fake titty…actually grab two fake tittys ;D.) but I also think it is dumb to be lugging around the old gas and wasting the space with the external if I do not have to. So, 1st I want to drain the internal tank, can I just siphon it threw the gas line? Or any suggestions would be appreciated.
2nd, after draining the tank, what are the next steps I should be taking to clean out the old tank? Should I completely remove the tank or just drain, fill up with some tank cleaner, gas her up and go for it? :-X
The tank it self looks like sh!t, but I assume it does not leak. The hoses and clamps must of been replaced somewhat recently because they look pretty good.

Beers on me!

I disconnected the fuel hose from the engine or maybe the water seperator and ran the hose out the drain in the bilge area. Pumped the the fuel ball and it started draining right out. As far as cleaning out the old tank cant help you i had to replace mine, it leaked slowly. If your tank has a sticker that has Perry, Fl. on it, it's the original tank. Mine leaked on the bottom of my tank smelt a hint of gas down in the bilge area. Put a large bolt in the gas line when you disconnect it and run it thru the drain to your holding tank. Good Luck...

been there, tried that, all i got was HIGH, the anti-syphon valve woudl not allow me to syphon,

mine had a lot of old gas in it, about 1/3 of a tank, i just filled her up added some additive, and changed the water seperator, she ran rough for a while :-/ but straightened up. ;D

Ok here we go,

1st removal of the tank is best! But if it is the oringal thats not going to be easy, and not worth the effort!~!

Remove the tank cover, remove the sender from tank, Then siphon all gas as low as you can.

Then take some old rags to get what ever is left. From here you can fill with freash gas and a new filter

Change filter after first tank and you good to go!!



My tanks come out, I was able to was with hose and let stand to dry, this is the best way.

I'd do a combination of Zebra's and Cy's posts...run the gass outta the fuel-line and as long as you get a good flow and no water, there's probably nothing to worry about...then put back new gas and new filter (gas treatment won't hurt) and you oughtta be good to go... ;) ...

Re: Internal tank
 

yeah agree with RAP that's what i did to my 250 Sea Ray and my 248 Wellcraft. Then just use the old gass as round up lol.

Re: Internal tank
 

Alright, I removed the tank cover and everything is covered in 30 year old foam and it did not look like there was anything to remove to easily get to the internal part of the tank, and that thing was not comming out with out a fight. So, Plan B, tried syphoning the gas out threw the line :P Oh boy after a mouth full of gas we quckly went to what 90% of you said, run it out. I switch the line from the external, to the internal and ran the engine for about 5 min, then shut her down for a few min. and reran her for another 5 min. The engine seemed to shake alott more then normal, but I guess that is tobe excpected.
Thursday i am going to run the internal dank dry ( is that OK for the engine??) then switch to the external to get back in.
Then put I new filter in, and go from there.
Thanks for the ideas/help.

Re: Internal tank
 

one more thing, when I have been running the engine I was using the ear muff thingamajiggies. But there is a port next to were the water comes out for the hose, can I run of off that port or is that just for rinse?
Probably a dum question but it needed to be asked ::)

Re: Internal tank
 

Sean...we weren't talkin' about runnin' the motor to get the gas out...take another look at Zebra's post..."disconnect the gas line...pump the bulb"...that kinda thing...the idea was to keep the old gas outta the motor ;) ...anyway, glad it went OK...didja get it all outta there?... :D ...


...and there are no dummy questions on this board ::) ...trust me on that...

...can ya post a pic to show us the other water port on the motor?...can't picture what you're talkin' about...

Re: Internal tank
 

what he said!! you do not want all that crap in your carbs!!

just get all you can out of the motor what ever way you can!!

Then I would add a new filter and fill with new gas, this way you running good gas with a little old but should be fine, change the filter after first tank.

As for the hose thing, I have never had one, but hear tell thats how you can rinse the motor out real well. But I am not sure if you can run from there??
