DIY Port injection set up

Originally I didnt have a return. Later iteration of the system included a return and a fuel pressure regulator

Sorry about the late post though i just completeld my return system using a walbro 460 lt per hr pump and it’s working fine. i just want to thanks everyone for their input which help me create mine.

 

Looks great. Glad it worked out

 

@Mark Ringor What are you using to hold the pump in?

Also is it a unmodified basket since you don't have the ring that Mason made to sit inside the basket without the retainer?

 

the actual walbro upper body is almost the same size as the oem pump. all i did is modify the fuel filter to suite the walbro pump. the filter doesn’t work now though, so i had to fit an external in line fuel filter.
My FP starts at 48 psi and it shoots up to 83 psi as i boost up. what i found was the car rans smoother and the part throttle KR dropped dramatically. i don’t know if it’s related to a colder fuel due to the return
