ON a Barry Grant fuel pump, which way do I adjust the return to increase or decrease the fuel pressure?

No regulator? My BG 280 had a baseline of 18Psi and used a Aeromotive # 13203 regulator adjusted to 5.5 Psi. 10/10/6.This message has been edited. Last edited by: TD3550,

Pressure to the regulator is controlled by the bypass valve screwed into the outlet side of the fuel pump. Loosen the check nut on the bottom and the top barrel will turn clockwise or counter clockwise. Clockwise will increase pressure and counter clockwise will decrease pressure.
