Default Fuel line lenth question

Just got a question or 2 on fuel line lenth.

1st.Is there a rule stateing the maximum lenth of fuel line allowed for racing 1/8th gp?

2nd.I was looking at a high ranked pro drivers car a noticed his fuel pump line was very long and I would like to know if there is a reason for it?I would of thought there was an advantage to running a long fuel line but not the other And his fuel line was not that long.I was thinking more as a short fuel pump line and a long as possible fuel line with a primmer to help get fuel up quicker.Is there and theorys on the mater or rules?

buggy can have 125ml and truggy 150ml of fuel in the whole fuel system. most extra long/dual fuel filter systems people put on their cars are NOT legal. however i never seen anyone measuring a fuel tank.

Its called Tech....if you win a race....you better Hope you aint storing an extra 10-15cc worth of fuel in the lines and filter...as you WILL be punished for it. if you A-main quality driver....i would not be attempting to run filter's and extra line just to make an extra 1/2 a lap....be smart and pit when your supposed to. ...loosing a race due to failing tech is a pretty sad way to go out.

as long as you are not running an external filter and gobs of fuel line you should be fine with the intank block "out" of the tank.

If you've got no filter and no excess line with the losi tank, you will be right at 124-125ml without the plastic block. I've had my tank measured numerous times over the past two years and it's right on.
