bushwhacker, was pumping bulb before, it acts the same way as always. doesnt stay fully compressed (lines clean from bulb to carbs). doesnt get too hard either though, but it never has. i am convinced its something in the motor itself, although i am still going to try running fresh clean gas first.

just got back from water test. idled around to purge any old gas, then got up on plane for a few miles, nothing wrong, no beeping, no warning lights, no godawful bucking. i wound up burning about 4 gallons of fresh ethanol gas w/ no issues at all. im going to try and get it pumped tomorrow. may not be the only issue, but its a good start. i dont think i have more than 20 gallons in the tank. thanks for all the good info guys, ill keep you posted.

The bulb is only to prime the system, after that its just a fuel line item, means nothing unless its being sucked flat. Once started and warmed up the motor should run with a fuel line stuck in the lawnmower can - just say'in

pumped out bad fuel today using an $8 hand pump from walmart. it would have been great if it were 2-3 gallons. 20, not so cool. saved all gas to see if there will be water separation. disassembled the entire fuel line assembly from the pickup to motor, blew it out w/ air, checked it for suction, everything good. new gas goes in, and we shall see. we have 37 public boat landings in the tricounty charleston area, and i swear 75% of boats use two of them, one of which is 2 miles from my house; or id go test it right now.

Any chunks of anything turn up in your extraction bucket? Anything in your fuel water separator?

What did you put the old gas in and what will you do with it?

no chunks, havent checked for separation yet. fuel is sitting in one of those grey storage bins, unsure of how to get rid of. any suggestions? my buddy has a landscape company, im trying to pawn in off on him. to be honest, the fuel doesnt look too bad.

Mix that gas into one of your cars. What I did is 10gals of fresh gas with 5 from the tank. My sons explorer went thru 50gals with no problems

Don't do that with a small motor with variable valve timing. Phase separation in the gas causes greater instability in ignition, and can lead to engine detonation even when the engine is tuned properly. That gas will probably be fine run in a simple overhead valve cast-iron motor, but many newer compacts should not run gas with water or phase separation.

I ran my 24 gallons of left-over gas from my recent "ethanol misadventures" through a friend's 1982 full-sized Ford Bronco. We ran it through a Racor water separating filter while pumping it out of my boat, and collected over half a gallon of water. We mixed in 14 gallons of fresh, ethanol-free gas to top off his huge 44 gallon fuel tank. No problems after that running it in his truck.

We had a blast at the mud-hole with that big-ole 460 ci big-block. I even was wearing my black clerical shirt and got spattered with mud. Some people thought that was pretty funny, a mud-spattered old priest ankle-deep in the mud, laughing like a loon. I don't know why.

ive got a friend w/ an early 80s GMC (bronco equivalent, i forget name) who could run it. my tundra is an 08, and id rather not risk it.

while checking the fuel pickup in the tank, i noticed that it is a 5/16 ID line, while the rest of the fuel lines are 3/8. its a strange design; 90' angle, barb fitting above tank for 3/8 line, barb fitting below threads on the bottom for 5/16 line. the pickup is just a semi rigid tube that was loose. i flipped it around and it is now snug, but cant get a hose clamp on because of threads above barb fitting. may try and replace whole assembly. they didnt have one at lowes or west marine in the fuel fittings section though...

fr. frank, i would pay money to see you in your clerical shirt at a mud pit by the way...
