Fuel line from tank to pump

[Peter Macholdt <vze2846b@verizon.net>]

I am planning to replace my brake lines with a ss kit from Classic Tubing.
While I was on the phone with them, they quoted a price of $140 for the fuel
line from the tank to the pump. That seems really expensive, even for ss. I
have a source for ss tubing by the foot ($2.95/ft). Can anybody tell me
diameter of the original line? I'm trying to avoid crawling on the subzero
floor to measure.

Thanks,
Peter
