Fuel System Questions
Hi - couple of quick questions regarding the fuel lines / system - (sorry if this has been covered b4 - struggling to find it in the search). I am
running a vauxhall 8v engine with fire blade carbs. At the moment I have the pump near the tank at the back of the car, then comes fuel filter, then
pressure regulator, then carbs. (in engine bay)
1: Do I need a fuel return pipe after the pressure regulator running back to the top of the fule tank? If so, can I move the filter and pressure
regulator to the back of the car near the tank and pump, to minimise fuel hose length for the return?
2: Do I need a brether pipe on the top of the tank?
Thanks as always
Matt

you only really need a return if you're using fuel injection. on carbs, once the regulator is up to pressure, it'll just stop flowing fuel
through it.
and yes you need a breather system on the tank, otherwise if you go out for a drive with a full tank, it may look like an accordian when you're
done  can't remember the exact valve you need, you need one that allows gas both ways, but not liquid
