Removing fuel tank - '74 911

[concentric]

Ok...

I'm on the attack against the junk in her trunk. I've got some rust issues in the front near the battery tray, so I've been doing some grinding in the front area. I noticed that some of the rust extends down into the junction where the tank seals to the frame, so it's time to drop the tank.

Can anyone give me a rundown of how I can drain the fuel, drop the tank, and get this done without destroying anything in the fuel system? I think I have the idea, but I'm looking for confirmation:

1. Disconnect fuel hoses into container and drain excess fuel.
2. Pinch hoses leading to rear of car so fuel will not run out and drain fuel pump dry.
3. Remove electrical connection from fuel tank sender
4. Remove clear hose that goes to somewhere on top of tank and hose that connects fill stalk to tank.
5. Support tank with board from underneath and jack up to break seal.

Any thing I've left out or issues that I should check into addressing while I do this process?

Thanks,

Jason

sounds like you have it...just be careful not to bend the spouts where the return/pump lines connect.

I hope you disconnected the battery?

I haven't done the FT removal part of the project yet, but fuel and spark don't mix well where eyebrows and face are near.

I actually will have the battery removed since it will be in the way of the project and grinding.

I didn't see it mentioned, and I'm generally a smart -a ss so don't forget the three allen head cap screws and brackets holding the tank in place. One in teh center and one to the left and right.

Other than that, you are all set.

If the car is drivable, run as much gas as possible out before you start to drain. YOu will be surprised how much gets in there. Clean the tank while its out so you don't have to do it later. 30 years old is bound to have some rust, dirt, old gas in there. There are many methods to clean the tank. Search the archives.

You may notice that rust has migrated to the lip seam around the tank. Clean and treat this as well.

Good luck

Yeah, you got me on the brackets there... I didn't put them on the list. They've been staring me in the face for a couple days while I've been working on this... That's the type of stuff I normally forget to add to lists and tell my wife! The obvious.

Thanks, JP.

Noah -- I thought the idea was to leave the bung alone -- let sleeping rust dog particles lie and not stir them up?
