Mounting a Holley Regulator (Orientation)

I have a low pressure fuel system on my car for my nitrous. I currently have a Holley Black pump and Regulator. I'd like to move some things around for better use of the space and a cleaner install.

Is there any reason I couldn't mount the regulator horizontal (so the adjusting nut is pointing to the side instead of verticle to the ground)? I don't see any reason why it would matter as the regulator is mechanical and basically a spring in a block, but I don't want to find out the hard way.

Thanks

The only mention that I remember is that you don't want to orient a regulator so that your g-forces can effect the diaphram. The g-forces can add to or remove pressure that the spring is applying to the diaphram causing fuel pressure fluctuations.

That makes sense. Thanks for the reply.

U have a low pressure stand alone on ur car, if so i was wanting to do that to my car and was wondering what it involves besides getting the right jets. High pressure stand alones just cost so much more $$$, lmk thanks

Yes I have a low pressure system for the nitrous.

I could tell you a ton of information about doing it from scratch but the best advice I could give you is to just buy the Nitro Dave's System or Harris Speed works system. They have built to fit parts and regulators that can run either low or high pressure. They are only about 100 dollars more than doing it on your own, but much easier and garunteed to work.

The main difference between high and low pressure is the pump/regulator and the fuel jetting at the kit. I run a Jaz fuel cell and a holley Black Pump/regulator. Those parts alone weren't too expensive but all of the AN fuel line and fittings cost a boat load. Probably 2-300 in fittings alone to get everythign setup and in the right places.
