6.0L Fuel Rest Pressure

[Winkman]

Can anyone tell me if a 6.0 should hold fuel rest Psi KOEO or is it normal for the fuel psi to drop right off after the pump Stops . Got 45 at Idle and Under full boost . Just wondering if i should change the Banjo Fittings/check valve at each Heads supply Line or the Pump or Maybe something else ? Should i be adressing this .

It drops to next to nothing very quickly after the pump stops.

Pressure is a little low at WOT, a blue spring update should be done soon. Make your own conclusion about the 6.4L banjo bolts...expensive little paperweights if you ask me.

Jimmy does this Blue spring update install in the upper fuel filter housing ? This is a 6.0 not a 6.4 . Got it apart so Now is the time

Yes, the blue spring update will increase the pressure from 50psi to roughly 70psi and goes in the upper fuel filter housing.

$38.00 AT RIFFRAFF and is well worth it
