hey coops,
on the rh there both for fuel,
it will depend on how you want to run your
set up as to whether you want to use both (all 4)
ie, if your running the occy you will need to run all 4 outlets
if ur running without the occy you really only need to use 1 on each side,
my memory's buggered so I cant remember if u use the front or back one,
if some1 doesn't chime in, just turn your petcock to either on or reserve and use
the outlet that the fuel flows from.
the other outlet will only flow fuel from the prime position.
