Does anyone sell a kit to delete my regulator?
the thing is that if you already have a regulated return fuel system on your truck, there is NO reason to go and start buying or modding it just to get rid of your regulator and go to a "flow control valve" ...
this would be an option to consider INSTEAD of having to pay for a regulated return kit and still accomplishing what needs to be accomplished..
keep in mind that the aeromotive regulator is a quality unit, and it IS a "flow control valve" if you think about it.. if you've already spent the money on it, then by all means leave it there, and enjoy it. it's got a gauge port on it and it is actually the best way to "control flow" if you understand the exact path the fuel must take. trust me i messed around with my FASS back and forth for months getting it dialed in to work with my ITP kit, and spending much time on the phone with DAN...
the regulator should be adjusted so that it provides enough backpressure between the FASS and the aeromotive to open the "bypass" valve inside the FASS. this is the second fuel output that goes directly back into the fuel tank and carries the 'aerated fuel'... you can put your ear to the fuel filler neck with the cap off to hear when this starts bypassing.. then you simply check the fuel pressure gauge on the ITP kit (or your own gauge setup) and increase fuel pressure until it reaches the level that you desire.
i have mine set at 62psi.. you don't want to crank the regulator so tight that the pressure is enough to stop flowing thru the regulator alltogether because now you are relying solely on the max output of the FASS to be your fuel pressure, and you are basically undoing all the hard work you did by installing a regulated return kit in the first place, because if fuel is not flowing thru the regulator and back to the tank, you have basically just gone back to a 'dead head' fuel system and you could have had that for free, it comes with the truck..
make sure the bypass spring in the FASS is the stronger one or you won't have enough PSI at the motor , but start w/the regulator backed off all the way. slowly tighten it until you hear the FASS start bypassing to the tank.
then you adjust to desired pressure w/out shutting off flow . it is easy to tell if you turn it too high, because you can actually hear the fuel stop flowing thru the regulator when it's too tight.. simply back it off until you hear fuel flowing again. then double check to make sure that the fass is still bypassing.
as long as both the fass AND the regulator are returning fuel to the tank, then you are in business.
word of advice, do NOT overtighten the regulator, it is possible to turn it too tight, and this will bind up or damage the spring inside, and even after you back it off, you will not be able to accurately control the fuel pressure anymore. i learned this from dan.
hope this helps..
