Guy’s I’m in need of more fuel pressure, I’m about to order a rising rate fuel pressure regulator 1:1 but if the pressure is regulated in the sending unit how Can I get it higher then when it’s pushing now?
Thank you!!

What is the reason you need more pressure? You would need to take the pump out and block fuel from going to the fuel regulator under the spiral spring. I ended up grinding down a stainless nut, and putting it between the plastic part and the spring so it could not move. Worked great.

Alright I will try this, I ordered my regulator so I will try this week, I run 7 psi and my injectors are at 95% duty cycle, it is dial in and runs good but I would like to get to 10 psi on 100LL
