I am installing a nx express single stage ford efi kit in my truck, do the solenoids need to be installed up and down or can they be installed side ways? Does that make a difference on the solenoid operation? Am looking for a good place to mount them and either way would make a difference.

they are made to be installed in any direction, upsidedown, sideways it does not matter

 

thank you for your help, is appreciated
