Ok here it goes.... I am installing a new fuel system on my 2000 mustang. I ordered a whole fuel system kit from MMR and received a box full of stuff... I didnt expect to get instructions but i also wasnt expecting to have 3 inline pumps. Do i take my factory pump out? Do i hook these other 3 pumps in series or parallel on the fuel lines? this is my first big build. any help would be appreciated. The pumps are 3 walbro gsl 392
