I bought a boat that someone had stuck a blue holley pump on... wasnt very quiet to me... maybe it was bad IDK. it worked because it was overpowering the float in the quadrajet and flooding the engine with fuel into the oil.. I replaced it with the proper marine carter pump and didnt need a regulator.
I used a cheap faceut brand pump in one of my cars that came with it installed for years with no issues......
Don't know what fuel pressure you are looking for. Mr. Gasket makes a ring and vane adjustable pump, adjustable to 15psi. I suspect a ring and vane pump to be a lot quiter than an adjigating style pump. T
