Yesterday at the ramp I went to fire my 35 GTR and it blew fuel out of the exhaust. I had it choked a bit. My 6 gallon can had 1/4 to 1/2 left and was bloated; the vent screw was open (cheap can from Wally world). I vented it and it fired and ran alright. I ran up river about a mile or so and when I backed off to get to my fishing spot it sputtered and died... I fired it back up and let it idle for a bit. Again the tank was bloated (after just venting it off). I filled the tank up a bit and it didn't cause problems thereafter. Valve lash was set 1.5 hours at my spring oil change. I assume the fuel in the exhaust was due to the over pressurization of the tank. Correct assumption?

yup

If the vent screw is open and its still bloated you need a new tank

If you had gas in you exhaust I bet you have gas in your oil. Better change the oil!

The tank is <1 year old. Can the vent be modified in any fashion? Guess I could fill it too Good point on the oil; didn't think about that. Sucks cause I just changed it 1.5 hours ago...guess a filter and some Amsoil is better than the alternative.

Definitely change oil and fix your cap. Some have a rubber nipple that will let the air in but not out, just cut or pull it out. Some have a white plastic piece that have to be drilled.

Thanks fellas. I just pulled the dip stick and it definitely smells like gas. I don't have a filter on hand right now so it might be a day or so before I can get new blood in her. Any harm in not draining it now?

So I have this POS cap. Reading the reviews on Amazon, it has caused people several problems

I did have a spare one of these on an old tank with a broken fill neck. Drilled out the black deal and it should work great, pending it doesn't leak gas. I need to come up with a better way to keep my tank secure/flat. I have the tank under my bow with a piece of wood under it, but the rake causes the tank to tip towards the cap. When they rigged my boat, they didn't use along enough fuel hose so my current options are shit! Anyone have a picture of their fabbed up tank braket. I may have some Aluminum angle lying around I can use.

BTW my oil reeked of gas. I appreciate the heads up on this, didn't even cross my mind.
Im going to run a quart through it before filling it back up.

You can add length to the line, get fuel hose at auto store, regular black good stuff, a brass nipple coupling and two hose clamps. Angle bracket for tank is just a frame for the tank to sit in, it will still have a lean to it, you can turn the tank if there's room and just have to pull it out every time to add fuel.

Hey deucem,

Pull that plastic piece and string that hold the cap with the can when filling up off. Then unscrew the vent knob on top all the way out. It is tough but it will unscrew all the way. Then take a small drill bit and without hurting the vent knob female threads in the cap drill it out. Enough that you can blow through it. Now reinstall vent knob and put cap back on. Your tank will now vent and not fill the crankcase with fuel next time you forget to disconnect fuel line.

BTW I'm surprised yours fired off. Mine was so full of fuel it wouldn't even turn over. LOL lesson learned for me to.
