Fuel Pressure Regulator part number is......

........Bosch 0 280 160 280

After my post here I have been investigating my 3.5bar fuel pressure. It would seem that my regulator is indeed a 3.5bar item, having googled it. As fitted to Volvo 440 2.0inj!

Bearing in mind my injectors are all the usual Bosch -744 "beige" type does it sound like I have the wrong spec regulator fitted?

I am not experiencing any other issues as the adaptives aren't all over the place coping with a rich mixture. I am wondering if the early cars (1996) are all fitted with a 3.5bar regulator. Maybe all of the 4.2s have a 3.5bar regulator. I was expecting 3bar as that is the pressure the injectors are rated at.

I'm thinking if it ain't broke.......

Any thoughts?

I thought the part was Bosch 0 580 254 957. 128 litres per hour at 5 bar

I think that might be the pump. I am taliking about the regluator on the back of the fuel rail.

Not sure if the 4.5 is different though?
