Default Adjusting fuel pressure

I pumped my 24v and I had a Fass Titanium 150 on it. Is there a way to adjust the pressure or do I have to get a new pump?

Restriction vs flow rate
Two different things remember. If line size is increased then pressure will drop but flow remains constant.
Not saying that is the case. It is just something to keep in mind.

is it the FASS for the 24 valve? if so yes it cant make enough pressure to feed the inline pump. you need to be in the 30-50 range 17psi will kill the inline

i dont think you will be able to adjust it high enough for what you need . you will be able to get it to start and run and idle around but i do not believe you will be able to use the truck with that pump.
