SCCA FUEL TEST PORTS

Valve Core Depressor Tool

Hand installed on sample port and depresses the valve core to control the flow of gas into the sample bottle. Machined for 1/4" (6 mm) ID hose (3 foot length included). This tool is necessary to access any of my ports; can also be used on GM and Daimler-Chrysler style ports.

Male Pipe Thread Fitting

The fuel sample port with pipe threaded end can be installed into any suitable hole or fitting. The correct thread tap to use is the NPTF type for maximum sealing capability. The use of an industrial grade pipe thread sealant will help prevent leaks.

Remove the cap and valve core.
Tap the part to receive the sample port.
Use thread sealant and assemble and tighten the fitting.
Inspect the assembly and remove any excess sealant.
Replace the valve core and cap.
Test and check the assembly for leaks.

Tube Fitting Connection

The tube type fitting can be attached to a brass or steel fitting with a suitable solder, silver solder, or brazing rod and flux. The steps in the fitting can be trimmed to allow the best fit in the available hole.

Remove the cap and valve core.
Clean all connection areas, apply flux and attach.
Allow the assembly to cool.
Replace the valve core and the seal cap.
Test and check the assembly for leaks.

Tee for Hose Installation

The tee type fitting can be put in a
1/4" (6 mm), 5/16" (8 mm) hose.

Cut the hose.
Insert the tee into the hose.
Hold the fitting in place with two hose clamps.
We recommend that you use SAE 30R9 specification hose and type "G" Hose Clamps.
For extra safety, a loop of wire should be added between the two clamps.
Cover with the cap provided to keep dirt out.
Test and check the assembly for leaks.

Banjo Fitting

There are some fuel systems (VW, Honda, Weber, etc.) made with a banjo fitting as the inlet.

Check the area around the banjo bolt for clearance of the Fuel Sample Port and acquisition fitting or fuel pressure test gauge.
Remove the bolt and clean it of all residual fuel with a non-flammable solvent.
Drill a 1/4" hole in the bolt.
Remove the valve core from the fitting.
Silver solder a fuel sample port to the banjo bolt or tap for a 1/16"pipe thread and install the fuelport.
Reinstall the valve core and check the assembly for leaks. Cap to prevent dirt from entering.
Tighten the banjo bolt into place using the head of the banjo bolt and not the fuelport.
