Just like it said would it be better to go with a Fuel Gauge over an A/F gauge if you spraying a 150 wet Shot? Or is there somthing even better I could Use over the two?

 

wideband with a guage and/or dynotune a/f lean shutoff switch.

 

Fuel Pressure Saftey Switch. By the time you look at the gauge to realize your fuel pressure has dropped signicantly it may already be too late. FPSS will shut off the system for you

 

Does someone offer a device that will to this automatic? And maybe more montior other things aswell

 

a/f lean cutoff switch. it is made by dyno tune. basically it will detect a/f ration and when it goes too lean it will cut off the nitrous. only 120 bucks. im going to get one before i start spraying.

i have talked to a few people with the fpss and they all say that it was a hassle and they took it off. im not sure why, that is what they told me.

 

I run a wet kit (or 3) and I run a fuel gauge, WB, and FPSS. The only reason I would suggest the fuel gauge would be if you had doubts about the pump keeping up.

The FPSS is what's gonna save your as though when it comes to pump failure. The problem I had in my last car was that the pump wasn't performing enough, but didn't fail to the point where the FPSS would deactivate the kit. That's where a gauge came in handy.

 

Great Point!

First off how many people actually have a fuel pump fail on a run versus how many have a lean condition? From our experience a fuel pump failure mid run is extremely rare a lean condition a lot more probable as numerous things can cause this.

Did you know that you can run lean, damage your motor and your fuel pressure can still be fine? You can have good pressure but not enough fuel volume your FPSS wont help. If you have a clogged or faulty fuel solenoid the FPSS won’t help. You have a clogged fuel jet the FPSS wont help. This types of issues are a lot more common than a fuel pump failing.

We sell quite a few FPSS but as noted above they sometimes cause problems and people yank them out. The a/f switch is the route to go!

I would go with the A/F Gauge and an FPSS.
If your pump is not keeping up as you up the size shot, you will be lean, you can see that in the AFR.
