im in the process of getting my gsr swap done and preparing it for BAR.
should i use the gsr fuel pump or would it be safe to use the walbro?
any info much appreciated. t.i.a.

 

anybody ???

 

So long as the pressure is at spec with the Walbro pump, then there isn't any reason you can't use it.

If you're just about to install one without a fuel pressure regulator, I'd advise against that. Walbro pumps typically flow more volume than what the stock FPR can return back to the tank. You will end up will higher fuel pressure as a result.

 

thanks for clearing that up.
