Hiab 650

Hi
Can anyone tell me where I would find the pressure valve on my hiab 650 and also where I would put I pressure gauge?

Thanks

I’ve got a 650 up the yard that I am planning to restore for a 13 ton gross Dennis DB15 ,I’ll have a look .

No hasn’t got one on ( a gauge that is ) but just tee in the pressure pipe to measure the pump pressure.

The green pipe is incoming pressure I think ? So iam pointing to the pressure valve .

Thanks guys,

Can I put pressure gauge where that quick release fitting is ? To the right of your finger?

Don’t see why not but I’ve not seen a fitting there before .
