going to be pulling my gas tank this weekend any advice or step by step or things to look out for?

HAVOC

Spray the bolts with PB Blaster the night before.

make sure it is fairly empty

I dont have a helpful clue but the filler neck tubes arent very fun

there's a drain bolt on the bottom, use it

Do it outside of and well clear of any buildings.

The fuel pump connectors are not any fun to disconnect. Especially if the tank has gas in it.

If it's like mine, it's a tight squeeze between the frame rail and the drive shaft. Might help to flex the suspension out so the RR tire is at full droop.

+1 on the make sure it's way down thing. Not so much for the weight, but when that fuel sloshes it can be real exciting trying to balance it.

make sure no one is smoking around while you are taking it out....

Drain the tank.

Look under the rear seat and remove the access panel hidden under right seat. Disconnect the fuel lines. There are 3 of them. Don't bend them up. The pressure side of the fuel pump is going to be tight. Use a double wrench on it so you don't twist the metal line. Be sure to mark the two rubber lines so you can put them back onto their original position.

Unbolt the filler neck from the body. The gas cap has four bolts around it. The neck has two bolts holding it to the body from underneath.

Place some blocks under the the tank and leave about a 6" gap between the blocks and the tank.

Unbolt the tank and let it drop down onto the blocks.

Unplug the fuel pump and fuel sender.

Drop the tank to ground and slide it out from truck.

All the above advice but, I like to place a hydraulic jack with a sheet of plywood under the tank. Loosen the the tank bolts and slowly let the tank down until you can acces the fuel lines and the filler connections. Spray the rubber hoses and silicone based lube to avoid damaging them. Once every thing is disconnected let the tank down and roll it out from under the truck. The jack makes moving the cumbersome tank in and out of positin much easier. Espicially if you are by your self and the tank is full. Good luck.

take the drive shaft out - its not that hard and it makes things easier

Label the two vent lines with PAINT so you dont mess em up.

Dealer has all the parts
-- fuel pump bracket
-- hard lines
-- flex lines
-- brake hard lines
(just got done with this but I paid to have it done - long story - the arrival of Keith had alot to do withfarming the job out)

It helps not filling it up a couple days prior!

Done mine a few times. Remove skid plate, 3 bolts per end (usually 12mm socket).
On a 1st gen 4Runner, you can access the filler hose and fuel pump under the rear seat. On a pickup, probably need to lower the tank a little to get to them. Also disconnect the level sender at the rear of the tank. 3 bolts on each end of the tank hold it up. I usually just get underneath on a creeper and pull the outer 2 bolts front and rear, then pull the one remaining bolt on each end and let it drop onto me. As long as it is empty (or nearly so) I don't bother to drain. First time I did the floor back and wooden blocks to support it, but when I found how light it was, I went with doing it by hand. Trickiest part is getting the EFI pump out of the tank, since you can't lift it all the way out all at once. You either need someone to guide it out as you lower the tank or else stop part way and ease the pump up and out of the tank as you lower it.

it is a pickup and i need to know how to get the main thoicker line out everything is un plugged...the same tank is going back in i have everything out just need to know how to get the main line off. without twisting the lines ofcourse

Which main thicker line? The filler tube would be the biggest hose, the breather line would also be big, or is this the high pressure line from the pump to the engine? For the pump line, I found it easiest to just unscrew and remove the pump as it is difficult to break the flex hose loose from the short hard line from the pump w/ damaging the hard line.

its the high pressure line...i would rather keep the sending unit in the tank....plus i prolly need to replace the high pressure line the comes from the tank and is about a foot long...how do i get those fittings loose

good advise i had a full tank when my fuel pump decided to go out and i didnt want to drain it cuz i didnt have anything that would hold about 17 gal. makes it 10 times harder

if its a truck and you just need to get to the pump, i would suggest pulling off the bed, about 8 bolts, pull it off, great access.

fuel pump is fine just need to drop the tank from the truck
