legal fuel tanks?
According to RC Pro Series rules (and ROAR as well I believe) fuel capacity for nitro buggies is 125 cc, including the lines and filter(s)...but every tank I see for nitro buggies has a 125 cc capacity for JUST the tank. What gives?

actually, at bigger races they do measure your fuel tank capacity. i know a guy that got DQ'ed because his tank was barely over capacity because it had heated up and expanded

copied and pasted from RC Pro website:
Fuel - Maximum 125 mililitres/cc includes tank, filter(s) and fuel line from tank to carb

Had my tank measured at both of the RC Pro Midwest rounds that I raced at last year (Dirt Country and St. Louis Dirtburners). I also run dual filters and I think I was just under 125cc's. I know the Kentucky State series measured everyone that was top 3 in the A Mains in each class.

So a "125 cc" fuel tank is not technically 125 cc...I've always run my fuel lines as short as possible with a single gutted filter for slow marshal insurance, but I'm going to have to check and see how much capacity I really have...I may have been cheating myself out of precious cc's!

Does anyone know how much fuel tubing needed to make 125cc's? I'm running the one kyosho fuel filter and a 120cc tank. I should have measured it before I threw the tubbing out. We actually had some random tests for fuel capacity one year.

The easiest way to test your capacity is to get a graduated cylider, fill your tank and lines, then blow all of the fuel out of the tank and lines by blowing through your pressure line. 125cc is 125mL on a graduated cylinder. Another method if you don't have access to a graduated cylinder, but you have a scale that can read in grams. Fill the tank and lines with water, then blow them into a container that is zeroed on the scale. The weight should be 125g as water weighs 1g per mL or cc.
