Hi, Peter,
 
Looks like the position of the fuel = pump fittings=20 is pretty much standard - but could it be changed if needed for your = hoses,=20 though.  Main thing is to keep everything going up to the fuel pump = - no=20 trapped air.  I used a longer hose from the gascolator to the pump, = with=20 enough length to secure it to the mixture control bracket and out of the = way of=20 the control arm.
