Rotax 582 fuelpump i series or parallel

I´m going to install a electrical fuel pump for my Rotax 582 and i have been reading around about different solutions and to connect everything in series seems to be the most common thing to do.

However i read in the manual for the motor and they recommend to make a parallel system?

So my question is what way i should go and also a recommendation for a fuelpump?

In series works well with a low pressure (4psi) facet pump.
Just don't use a "lookalike"pump.verify your max pressure is within rotax reccomend actions before flying.

Great thanks, will order a suitable facet pump then!
