So i have two working fuel pumps, and can’t decide which to use on my 88 XJS V12.
Walbro GSL391 - Flow rate 190LPH @43.5psi
Bosch 69536 (580464008 with turbine tech.) - Flow rate 130LPH @43.5psi
I’ve heard the Bosch turbine is better tech and quieter, and 130LPH should be fine for up to 350hp, so I’m leaning towards the Bosch.
