You've already got a pump set up to drain the tank... You just need it to drain to somewhere useful. Find a convenient fuel line junction to disconnect, and direct it into an appropriate container. Find the fuel pump relay and short the contact terminals, or if the pump wiring is easy to access, find a connector and power it directly with a battery or something. Just make sure the area you're working on is free of fuel vapors.
Ok, siphoning is done. Now I must use the truck's fuel pump, or I have to take the bed off / drop the tank. I got out 21 gallons and then I couldn't get the siphon hose dipped into any gas anymore. There's 3 gallons left and I have a suspicion that those are the worst 3 gallons.
How about cutting on both sides of the filter with some heavy duty diagonal pliers and then using high pressure fuel hose, hose clamps and a barbed type fuel filter (high pressure type) to bridge the gap you will leave?
If the metal hose gets crimped shut as you cut it, use one of these and cut back from the crimped section:
I always dump Isopropyl alcohol in any gas that's been sitting around before using it.
Worst gas I had recently was when I was short for my mower at the beginning of spring, and I had a can sitting around with 3 or 4 years worth of fuel filter drainings in it... this stuff was yellow, looked like a cross between light machine oil and pee... in it went... gah... didn't start too well, in goes 4 oz of methanol (I was out of IPA) and I shake it up some, get her started, do the front and back lawns, and was trying to hack down an overgrown bed and stalled it, couldn't get it going again... maybe just maybe I should have fresh gas in there... gave up for the day.... so a week later I drained the half jar of milky syrup that was left, and put fresh gas in, and she fired up fine.
lol ive "fixed" someones mower doing that. they brought it to me sayign it wont start/stay running i look in the gas its full. i ask how old it is they said maybe a year lol well after about 10 minutes of messing with other stuff and finding out it will run if i spray somehting combustable into the air intake and it spudders to life then dies. well i drained the old gas that to my suprise looked like iced tea (year old my butt) put fresh stuff in and it fired right up!
funnily enough I got that mower as "dead, for parts" 'coz it had 2 stroke mix in it, when it's a 4 stroke B&S.... if I'm interpreting the serial # stamp right, it was made in 1968.
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
I can remember when my sister first got married she was way too poor to buy a mower. They could barely afford the house payment. Dad & I went to the dump, and picked the best looking mower out of the pile and threw it in the truck. Dove it home, drained the crankcase and fuel tank and refilled it with fresh oil & gas and it fired right up.
