I bought a FPSS for my Nirous Express wet kit. I've seen some people on here say that they dont like them. Are they too sensitive(or a pain to adjust)...or just don't work? Should I install or not?

 

I had one as it came with my kit and I hated it. It constantly turned the kit on/off all the time because of our returnless style fuel system. I even tried to adjust it all the way down to 15psi and it still did it. I took it out and have been happy ever since. My personal opinion is who needs that crap.

 

worthless you should never see a drop in fuel pressure unless fuel pump is bad
