My_XR6_Turbo Member 282 Member For: 20y 3m 21d Posted 15/04/19 05:45 AM Share Posted 15/04/19 05:45 AM Hi guys, I'm installing a walbro 460 intank pump and I know I need to drill the return line out to 4.5mm. Is this the right one? Can anyone explain what the center one is for as it's blocked? Thanks, 1 Link to comment Share on other sites More sharing options...

I was under the impression you needed to drill out the return hole in the fuel pressure regulator itself, or purchase the bolt in GFB one when installing high flow pumps. 1 Link to comment Share on other sites More sharing options...

Thanks, The centre 1 is used to hold it into the bottom of the pot, ( the locking pin ), I drilled mine out to 4mm, certainly quietened down the pump audibly, AFR at idle settled from low 12s to stoich, so it made a difference, though as suggested by BEERTURBO, just buy the GFB drop in reg Link to comment Share on other sites More sharing options...
