When to drop the gas tank

I've got some UCA frame mounts and LCA axle mounts to reinforce, as well as a rear trackbar axle bracket to reinforce.

Do you drop the tank when you weld that close? Mostly the trackbar axle bracket is what I'm asking about...

Maybe its safer to drop it, but I never have and I've welded in all those areas. I just try to stick something between what I'm welding and the tank or fuel lines. Normally its thin steel plates but occasionally a non flamable blanket also helps if I can't get a plate in there for some reason.

Jeep parts available, $30 each:
Camo seat covers
Passenger side window OEM soft top
TJ rear drum brake pads

Most everyone gets nervous making hot sparks around the gas tank, but remember, it's the FUMES you're worried about.

You're not welding right on the tank. As long as there are no fumes coming from nearby, you should be okay. This is a time when it might be okay to have a fan set back a behind you a bit and running on "low"......just to keep a bit of airflow. Obviously you don't want it blowing right where you're welding, but just enough to get rid of any fumage.

Fill the tank all the way up. Less chance of fumes being here. Due the welding outside not in a garage. This allow the fumes not to collect in where you are welding.

A 89 yj with a 4.0 aw4 sye out of an 92xj. Now the hard part is done time to get it up in the air just a bit. Working on 8.8 with 3.73 and lsd for the rear. and new D30 hp with 3.73 .
For those who have not figured this out I'm old school but can handle the new too.

Not to mention that if you DO blow it up, you won't blow your garage and house with it.

Ok, thanks for the replies. I'm not so worried about the fuel lines... just shield them from damage, etc. The tank also has a skid around most of it. I guess I could get a welding blanket and try pinning it up under there to shield everything from sparks.

I've been looking at doing the outboard rear shock deal and I think dropping the tank is a good idea. I had my tank off to install the Kilby skid and it ain't that big of a job. Good time to get all that muck and ire cleaned off as well.

x2.

Support it, unbolt (I think it's like 7 bolts), unplug sender, fuel line, return line, and then move it out of the way. Should take less than a 1/2 hr IMO

Yeah, I guess I'll wait and drop the tank and do all the welding at once.

Fwiw I just did my shock outboard this past sunday and didn't drop the tank. I put a welding blanket up around where the fuel lines were and didn't have any issues

In a ZUK now....

Yeah same here, I outboarded the shocks with tank in place.

The top and doors on this vehicle are designed only for protection against the elements. Do not rely on the top and doors to contain occupants within the vehicle or to protect against injury during an accident. Wear seatbelts at all times.
