I was curious....i was helping my buddy install his nitrous kit..i was running the lines, he was mounting all the relays, solenoids and such. Well i noticed that he moutned his fuel solenoid up-side down...with the bracket up..and the nitrous/purge solenoids i belived were mounted sideways on the fender. Does it matter how the solenoids ae mounted? They dont have to be up right to work properly do they?

 

No, they'll be fine. TNT soleniods are actuall placed on there sides when mounted properly. There is nothing in there but a electronically controled valve, so you can basically mount it wherever you want.
