Alvyn,
Got the fittings with it when i bought the pump so i'm confident they're ok. FSE says 4.4L / min anyway she is spot on with what i'm getting...but whether its 4.4 or 5L / min should be loads more than a 300bhp cossie needs. Question is if there's another way to simulate on load setting other than pre-loading regulator?

Old Ford,

Have tested the regulator by using a pump on the vacuum pipe.

thanks
