Any tips for removing the fuel tanks while on jackstands (no lift)?
I assume this can be done w/o removing the drive-line? I have a siphon pump to suck out all of the fuel and know my way around a C5, but I've never removed a tank... only replaced a pump or two.
Any tips/tricks etc. would be much appreciated.

don't smoke a cigarette while you work
it will not be any fun on the ground, use a jack to support it and a 2nd pair of hands will be much needed. You'll need to get the car high enough (basically the height of the tank)
put some vacuum caps on the pump leads and you can keep from spilling it everywhere

Is there a way to do this using the fuel pump? I.e. disconnect the line from the main fuel rail and pump it into a fuel jug so I can put the gas in my truck?
I have a hand siphon pump and was planning on just sucking it out that way.

The only thing I'm not sure of is whether he ran the fuel pump through the OBD computer or by just turning the key.

I drained my tanks recently to scale the car with no fuel. I didn't have a pump of any kind so I simply removed the aluminum covers/supports, disconnected the fuel lines at the bottom of each tank and drained them into my 5 gallon race fuel containers.
Pulling the tanks won't be half as bad as putting them back in.

What year? MY2003 and earlier are a lot easier than later years. If your car is a 2003, look at the spid label in the glove box and see if FFS is one of ther option codes.

It's a 2001 so it doesn't have the fancy C6 system my old 2003 vert had.
Scott.... how'd you support the tank when you took the metal support off? I accidentally unbolted the thing last summer not realizing it supported the tank... had to bench press it in place and get the bolts started back!
Wally.... When you turn the key on the pump only primes.... wonder how to make it just run w/o turning the motor over.

Yeah I vaguely remember him saying "we can use the computer to run the fuel pump." I guess they had a tech II or something like it to force the fuel pump on.

Remove the fuel pump relay from the underhood fuse panel and jump the two terminals with the key on. I can't recall which two, but they are on opposite corners where the relay plugs in.

The crossover tube should keep it from falling out if it acts like it wants to. You could always stick a jackstand under it.
The problem we had was putting the tanks back in. We had to use the weight of the car to push them up in the slots.

Does the cage builder have to be really careful to get the main hoop welded so the tanks can get back in? I assume he'll need the tanks for fitting purposes? Or, is it not really even close, but you just need them out for access/safety?

Tank systems were WAY different in the 1999 FRC then the 2003 ZO6.
Driveline and exhaust stayed in the car...
