RB25de replacement fuel pump & regulator help

[ossy]

Hi,

 

I've got a R33 RB25de that has some running issues and believe the fuel pump is buggered. I believe the NA pumps are same as GTST's but can't find any online, except uprated ones like  255lph Walbro or 340lph Kemso. I was going to buy one of these but was told they may make the car run lean and that the stock fuel regulator might not be able to handle the increased pressure.

 

Any recommendations/ideas if either the Walbro or Kemso pumps will work without causing any problems? Thanks.

If the n/a pump is the same as GTST then the Walbro will be fine.

Thanks, will go for the Walbro. Heard same from few others also.

Don't really trust the Kemso, seems waaay too cheap at only half the price.
