Question Anyone using Magnafuel boost referenced regulator?
https://www.summitracing.com/parts/mrf-mp9925-b


I know this should be in the fuel section, but it pertains more to boost to me.
Are these any good or good enough?
Any issues with them?

I'm using one. No problems whatsoever. Holds fuel pressure like a rock.

I have one, only issue I have is that it doesnt hold pressure after turning the car off. I have to cycle the keys twice before it starts after sitting for a while

Is that the regulator or fuel pump messing up?

Regulator. Did a lot of testing and Magnafuel told me its not designed to hold pressure after the pumps turn off.

If you don't want a 1:1 rise of fuel pressure... Get a 9950

I'm on E85 & haven't had any issues with my magnafuel MP9950B-BLK. It's a 1:1 boost reference.
