    Default NOS question

    Gotta question for u guys. I have seen a couple folks use the same fuel pump that feeds the motor also feed their nos supply. I have a quickfuel 175 gph pump. I am pretty sure the pump would handle it, but I wanted to ask. I was in the process of finishing up my nitrous system, and I want to make this look as clean as possible, but still safe and functional. I got the money for a dedicated pump, and WT and I already ran the wires for it, but it'd sure look cleaner "T-ing" off the main supply line to the solenoid rather than adding all the other parts. Any suggestions?

    You can use your pump but, you will need a regulator for the NOS fuel system! And do you have the regulator at the carb with full pressure to the carb regulator? This way the regulator for the NOS will have good pressure for flowing the system!

    The fuel pump that I bought has the regulator mounted in the housing.

    That will make a problem, maybe! Example, If the fuel pressure needs to be 6# at the carb and 6.5# at the NOS you can't do it! Now the other way around yes it will work! Lets say 7# at the carb and 6# at the NOS that should work!

    I run mine on the same system and I have a pressure gauge on my nitrous fuel line right before the solenoid to make sure the pressure is where it needs to be when im wot and on the spray since they are both using the same fuel supply.

    I have the psi set at 9# for the motor, the kit I have says to set it at 10# for the nos. Wonder what would happen if I set the whole system at 10#?

    Wow! The NOS chart said 6# so I set mine at about 6.25 free flowing thru the nos fuel jet. When I tested on the water at wot on the spray it dropped a touch under 6.

    My kit is a nitrous express, not sure if they set up their plate systems differently than nos. Didn't mean to confuse you guys with the brand. On my jet chart, it says 10 psi

    Josh I would think 10 at the carb would cause it's own problem. Seems like alot to me. My QFs act stupid with anything over 6.5

    I would put the psi at 10 and see if the needle and seats hold first. You will probably end up dropping the psi close to 9# to make it hit good if it's a real safe tune chart like the nos. I'm new to this myself and just passing what I have learned.

    Well, I decided to not be a tight wad and do it right...ordering a designated fuel pump. I'll plumb it all right with it's a own supply and regulator. Had to stare at the minimal space I had for a while to see how I could route it. I'll post pics this weekend after I get it finished up.

    Josh, you should not need 9# fuel pressure at the carb at all! Reduce that to 6.5# and see what happens! I had an issue with my NOS, fuel pressure was to high and it killed the performance BIG TIME! All systems are setup different but damn 10# WOW! Im just saying!
