Xantia–Help Interchangeabililty of pressure regulators

[lancia58]

Hi

Does anyone know what are the differences between the various circuit breakers ? Externally they look the same. On my car ( Xantia 2.0 16v Automatic hatchback , make year 2000 ) the Citroen part number is 527419. Do they vary between the different engine types ? Do all of them regulate the same pressure ?

Thanks

here is a listed for some MK1



95 574 618
CIRCUIT BREAKER
- BVM AND BVM BE3 EXCEPT INJECTION XU10J4R

5274 11
- INJECTION XU10J4R AND BVM AND BVM BE3

5274 10
NFP
- BVM AND BVM ML5T

96 172 847
NFP
AR
- BVA
although i think the last one is for the rear end

and here is a list for some M2

95 574 618
CIRCUIT BREAKER
- INJECTION XU5JP
- INJECTION XU7JB
- INJECTION XU7JP
- INJECTION XU7JP4
- TURBO DIESEL XUD9TE
- DIESEL TURBO XUD9SD
- TURBO DIESEL DW10TD

5274 11
- INJECTION XU10J4R

Are they interchangeable for instance is the 574616 interchangeable with the 574619 ? If not what are the differences ? Is it only different bracketing ?

Same block, different spring pressures so affecting the regulated pressure. You can fit different ones to your car but it will change characteristics of the system.

Hi

Is there a way to know the characteristics of 575616 in compare with the 574619 ? BTW what is the reason for the diffrent spring pressure ?

Thanks

With some pressure regulators the overflow outlet is at a different angle so worth checking that out.

[lancia58]

Can the outlet be detached from the regulator ? Can the outlet be swapped between regulators ?

Thanks
