will this work
 

i have my setup now using a 140 gph pump but i still have the pump up on the front of the motor that im not using i was thinking would i be able to use this as my seperate pump for my nitrous system i would be using a 150 to 200 shot direct port kit and the pump would be strictly for the nos this is the stock pump that im not using any suggestions would be greatly apriciated.

The mechanical pump? I wouldn't.

Take care,
