Recording this for future use:

Check valve: 8567T12 | Type 303 Stainless Steel | 1/8" NPT Male/Male
Temperature Range: NPT Male: 35° to 300° F
Maximum Pressure: NPT Male: 200 psi @ 300° F
Cracking Pressure: 2 psi
$21.16

Coupler, to be welded in UICP: 4443K661 | Type 316 Stainless Steel | 1/8" NPT female x NPT female
Maximum Pressure @ 72° F 3000 psi
Max Temperature: excess of 350F
$4.61

Nozzle: 4759T15 | Brass fogging nozzle | 1/8" NPT male
Maximum pressure is 3,000 psi
Maximum temperature is 450° F
$24.39

Nozzle selection is still TBD depending on fueling requirements. The majority of the selctions are NPT male however, and will require some sort of bulkhead fitting to join the NPT male of the nozzle to the plumbing hose of check valve if installed at the IC pipe. My current thoughts are welding a female/female NPT coupler at the IC pipe before the throttle body as discussed earlier. Installing the nozzle from the inside, the check valve on the outside, and routing the plumbing to the check valve from the pump assembly.
