Fuel Pressure, what's too high ?
My walbro is pumping at 26-29 psi. I have the stock plastic fuel filter cap. I hear you don't want to go over 30 psi with this setup. Opinions ?

Thanks.

I've heard 30 PSI with the stock cap and anything over that will need/require the billet lid. Get that and you can pump 42 PSI no problems. That's what I intend on.....
