removing gas tank for rollbar?
removing gas tank for rollbar? seen this mentioned on wolfes site. it is really needed? i dont see it being an issue myself. more of a safety issue of lawsuits if they dont put the warning up.
I dont remove it but I TIG everything and we are extremely careful. There is a chance of blowing thru the floor and sending sparks onto the tank.
I tried it leaving the tank in (98s are a royal PITA to get the tank out), it was all going fine until one of the plastic evap lines was a little too close to the floor apparently and caught on fire.
Luckily except for a melted line nothing bad happened but it could have been worse, next time I'll drop the tank

When we welded Trigger's bar in, we dropped it. I wouldn't want to weld a bar in with it up. It only takes 30 seconds to pull one strap bolt out of each strap, and drop it down a few inches....
I welded mine in with the tank in.
I felt like Clint Eastwood was saying "Do you feel lucky punk"
If you have the trap door mod and lower the tank a little you can slide a fire blanket in for safety sake. If I was TIG welding I wouldnt worry about it.

Every one is different, the question is if a shop burns down a car will they replace all of it.... thats the part I'd worry about. I would almost pay the extra 1 hour of shop time for that Assurance.

I didnt drop the tank on mine but it did get pretty hot while welding the plates to the floor.
it turns out it is easier to melt the plastic fuel lines under the floor by the drivers foot well when doing a ten point.

Whether or not its normal for that line to be there or not I dont know, I just consider myself lucky I seen the black smoke and got it out before it caught more stuff on fire - especially since my garage is attached to my house lol.
thats only for LT1 cars. LS1 cars have steel line into the engine bay.
I hate welding SFC on LT1 cars, for the same reson

If I was getting paid to do it the tanks would stay in unless the cutomer wanted to pay extra to remove it, you probably have a lot better chance of messing something up dropping the tank then welding near it.
If you have the time and are unsure of your welding skills I would drop it..
The only time I seeing it that quickly was a car that had the exhaust before the axle and most times would have all the shields removed.

I feel a little more safe when welding the back bars in a 98 or older car. 99 and newer have plastic gas tanks.. Heat, gas and plastic dont go well together . If your not a experienced welder drop the tank

My friend caught his car on fire welding in his cage. His car had the trap door not sealed all the way, hit a fuel line, didn't realize it for a few seconds until it started getting hot around his legs, and the whole thing went up. 4 fire extinguishers later it was out, but looked like Brady's car after it caught fire.
