[Mk2] [Turbo] big power mr2 not holding fuel pressure after turning off?

Post by mr2c8cya »

noticed my corolla 3sgte holds fuel pressure long after turn off, then looking at my 2 which has a walbro intank pump, 2 litre swirl pot, bosch pumps, 1200cc injectors sard twin feed rail and braided lines throughout oh and aeromotive reg, as soon as i turn key off losses all pressure<
is this normal? or do i have a leak?
many thanks guys

Where are you reading the pressure from?

It's off the gauge on the reg, so surely should hold pressure between the Bosch and the reg I would have thought

It would if the non return valve has not be removed from the pump.
Do you have a photo of the pump outlet?
