Default schrader valve for fule

as far as nitrous goes i know that i want to go with a plate kit, and iv been searching and see that everyone is using the schrader valve off the fuel line to supply the fuel. obviously it works and im not trying to say it dosen't, but how do you still have equel fuel pressure to all the injectors, dose the pump supply enough fuel to keep the pressure up. just wondering becouse i would think that fp would go down because of that, if some one could shine some light on it thanks

everybody uses it so id imagine the FP keeps more then enough pressure up there for stockish engines.

I log fuel pressure, I have seen drops from 62 PSI to 35 PSI. Longest I seen it last is .7 sec. As long as the pump recovers I am told its OK.

WOT NA I usually see 62 PSi drop to mid 50's and recover.

worked just fine on my stocker, with a 255 pump and hotwire kit, now with my 402 i am not sure it will be a good idea. I will find out on the 30th when she gets tuned.

I did not like this setup either, so I just went ahead and set up a standalone fuel cell. No worries whatsoever now And C16 in the cell..

There will always be a pressure drop weather you are NA, Boost, or Nitrous. As long as the drop isn't longer than a split second and the pump recovers pressure you will be fine.

My fuel pressure was bouncing back and forth on a 100 shot (410rwhp on motor) from the shrader valve with 255 Walbro and hotwire kit. So I added a 2nd Walbro intank pump. Now the pressure stays rock solid.

If we move the fuel pressure regulator will it be better?
