Drain fuel without dropping the tank

Is there a way to drain the tank without having to drop it? Maybe jump the fuel pump relay?

I need to drain out some old gas, and I don’t have the time or resources to remove the bed. If I can maybe slip in a narrow siphon, or even jump the fuel pump relay, that would be great.

Thoughts?

 

Undo the line at the fuel filter and then jump the relay.

 

You can certainly get a syphon in there.

 

my motorcycle shops have a hand powered pump to drain fuel tanks......

 

Good way to go, avoids possible spark by using electrical ones.

 

This is a Pic of the inside of the 18.5 gallon gas tank. That flapper cover on the end of the fill tube messed with me when I tried to put a siphon in there to get old gas out. Hence me pulling the tank while troubleshooting a tacoma that had very old gas in it. My 2 cents.



I have pics of all my Tacoma repair adventures. It needed a cleaning and got a new fuel pump and sock.

 

Dang.

 

Well crapola

Thanks Moonrman
Learned something

 

Remember the old days when there was a drain plug in tanks? WHAT AN AMAZING ENGINEERING IDEA…..ugh

ok
I’m on TN’s idea now

In fact, I would much rather buy/install battery (worse case a starter too) than take off bed or drop tank

disconnect fuel supply line/pull fuse and crank her till bad fuel out

 

I found this video online: https://youtu.be/ulErVVua244

It looks pretty simple, but it seems like the picture you shared doesn’t have the same removable plate. I don’t know what mine has.

 

IIRC, I could push it thru with some force but I could not get at the bulk of the fuel. ( to the good spot on the bottom in a low area of the tank ) I had a half of tank of gas and siphoned some but I think I was fighting with the tub that surrounds the foot print of the hanger assembly. And when I was yanking out the hose I knew something wasn't cooperating and i didnt want to break it. Yeah if you don't need to drop tank. I understand, I'm a common sense guy also but as you can see from pics my tank was bad and I didn't want that crap in my newly installed engine. Whatever works for you is best. Cheers

 

Yeah, I feel the same about my engine. I haven’t seen the condition of the tank yet. I’m going to stick a bore scope in it and see if there’s much sludge/sediment.

There’s only 69k miles on it. I just got it. I have to drive it 400-500 miles home, so I’ll probably just drain whatever I can and put a new filter on it, and deal with it when I get home.

 

If thats the inside of the tank I wouldn't even bother and replace the tank.

 

Whatever, if you want to spend an arm and a leg or get a aftermarket tank. Mine polished up beautiful with dawn dish soap and a pressure washer but to each his own.

 

Do you by chance have the part# for the filler neck tube that goes with your VIN
I am very curious if my 97 is the same part with that little screen at the end inside the tank

 

I didn't replace anything on mine but the fuel pump and sock. So no sir. Sorry. I have the 2001 FSM but it does not have part numbers.

This shouldn't be that complicated.

What engine do you have in your 1995?
2.4, 2.7, or 3.4?

Work smarter, not harder.

If you give me the engine. I can probably provide a diagram of the fuse box and relay to jump.

 

Just take the plug off the top of the tank and use some alligator clips to a tool battery. That's how I drain the tanks. Slide a piece of 3/8 line over the output flare. The actual relay is up under the dash behind the steering column to the left, sucks to remove and to jump.
