i have a 500 magnafuel pump and a magnafuel 2 port reg for carb i run a mallory reg for my 150 shot fogger , my question is .will the mallory reg for nos be ok with the pressure creep i get cause i dont use the nos much i know alot of folks use a dead head system but is that at the track ,where its not on for hours like on the street or should i invest in a 0.19 bleed and run it back to the cell thanks for your help... :?:

You'll get a lot of different opinons on this one... IMHO if you want to avoid pegging your gauge all the time when the nitrous is off put a bleed on it.

i have a
magnafuel 300 with a mallory reg. on thecarb
personally spend the money buy the holley reg.especcially for nitrous
cheaper than rebuilding the mallory
and i put a bleed on mine to save it

check out magnafuel.com under parts and accesories "fittings" part#3110 just install the fitting w/bleed after the regulator with a -3 line to the fuel tank or cell using a -3 bulkhead fitting unless you have multible stages of nos then you can use a fuel block and run a - 6 or a -8 line to cell or tank
