I will be running a 125hp shot of dry Zex and was recommended to use a fuel pressure cutoff switch. What are you guys running? What company/part number should I look for (so I can make sure it fits). I have a walbro 255lph pump already. Thanks ---

 

This is the FPSS that NX sells

What ever company you decide to buy the switch from you will need to make sure you get one for an EFI high pressure fuel system and you will also need a manifold.

 

I'm running the NX piece, the one in the link above to be exact.

 

it is on my car also

 

Another option would be ours:

Since you will be running it with a dry kit make sure you get an AN cap to cap the other end of the manifold so fuel doesn’t shoot out everywhere lol:

They are all basically the same part... made by Hobbs (part of Honeywell).

Oh , I see.... thanks guys ---


BTW How big is the bottle (lb) on the dry zex 82018 lt1 setup I have? I have that setup, with a purge kit, safety blow down, bottle heater w/ bottle cover, pressure gauge, and a purge light .... I will be ordering a safety fuel pressure switch and remote electric bottle opener, is there anything else you all recommend? I am using a walbro 255lph pump. Thanks ---

 

The Zex kits come with a 10# bottle.
