car is running lean on high boost (1.2bar) still has std pump,fpr etc, not checked voltage at pump yet or changed filter but wondered when they need changing.

please note dont want to change for sake of it,

 

Pump mate. Cheaper and easy DIY job.. If the filter has not been changed when serviced then do that as well as only a few quid and very easy to do..

 

would a pump be struggling on std import with fmic,cone,stainless,safc and 1.2 bar of boost??

 

quite possibly mate. Depends how old the car is as like any other part, they wear. Also you are running more boost than standard so more juice is needed so the pump obviously has to flow more.

Walbro 255 will sort mate, about £100 off fleabay and there a doddle to fit mate

 

As above, I would do the fuel pump as its not expensive and easy to install - I did mine yesterday after following a guide on JGM's site here:

JollyGreenMonster.co.uk

Got mine off Scoobyworld, they were the cheapest I could find and was delivered very fast as well

Cheers,

Pete

 

As stated, depending on the age of the car, the pump could be getting tired. Filter is worth changing too.

Walbro pumps can over-power a failing pressure reg IIRC.
