guys,

I need a very quick response, so I am here.

Recently, I have my Ford T-6 installed a tuning chip that increase maximum rail pressure of about 10% over standard. However, this extra pressure keep drainning off. This means, there must be a rail pressure relief valve somewhere along the high pressure fuel line, that needs to be strengthen (just like the older models), but we just don't know where it is.

As a system standard, I am sure that all commonrail diesel must have the pressure limiter valve somewhere, but most new models do not have this valve on the rail.

Anyone could help me out about this relief valve location?

Thank you very very much.
