What's a quick and safe way to remove about 5 gallons of bad fuel (it looks like chew spit) from my 94 s10 Blazer?I've never siphoned before,and I'm broke down at a friend's place.It's going to be 26° tonight,and Chevy's my only shelter..if it matters,it's a 94 Tahoe LT 4 door,4 wheel drive,4.3 Vortec.Please help!

yes you have to drop the tank. you will also need a fuel line tool to unhook the fuel lines. before you drop the tank see if tou can reach and wiggle the electrical connection on the top of the tank. these pumps have a pigtail issue. please rate

There is a vaccuum operated switch located on the transfer case that sends vaccum to the accuator that pulls a cable that locks the front end in. Check for vac coming in and out of this switch if no vac out replace it. This switch is a very common problem. You can find them at most parts stores in the help section #49315. please rate.

SOURCE: 4-3 vortec gas in my oil 1994 s10 blazer . vehicle was running

it doesnt take long to ruin the engine diluting the oil with gas - i dont know how i dodged that bullet, mine was leaking -gas into the oil- new spider is only the beginning of the care and feeding of the unpowered poppit spider motor- regular bottles of injector cleaner will keep them poppits clean, otherwise fuel deposits mess up the quantity and pattern of the fuel spray quickly from new- i had long suspected the new spider i installed was faulty, (Sorensen), but it was just quickly plugged by fuel deposits-as i understand it, the additives often in gas like to hook up in the poppits- my 1994 4.3 S10 kicks **** now, runs like it did when i bought it 5 yrs. ago, smooth like its supposed to, i was chasing the piggy/miss for two yrs, bottles of injector cleaner didnt help, it needed a heavier mix of cleaner
- it couldnt hardly get itself and a little aluminum boat out of a easy boat ramp, what broke free the deposits was doubling up on the amount of injector cleaner i dumped in the tank, when a person takes a clogged injected vehicle to a shop they hook up a pressurized system to it ,and disable the fuel pump -shop air system is better than aerosol can system, force the engine to run on a <10%> cleaner/gas mix for 20 minutes, guess i did get lucky with results from the cleaner addtive, cuz the real fix is find a shop that does the 10% cleaner 15-20 minute pressure wash of the injectors, and it should be done at least every year- mines running so good now, ill not see a lot of results from the pro cleaning i'm scheduled for tomorrow morning - hate to cancel tho- these unpowered poppits are very finicky - i did reuse my plemun half shell gasket, it has the red rubber line on it and it was still live so i reused it

It can be done but it is very time consuming.
I use an 87 Astro van intake sensors and computer on my 86 OMC.
After six years I am still playing with it.
Runs good and easy on gas.
Got lots of info from DIY-EFI.
You HAVE to change programing in the computer.
I am running a closed loop system with one oxygen sensor in the starboard manifold.
Your 94 computer is not as good for a boat because it also controls the transmission.

Just to give you an idea what your in for.
