Installation Instructions for By-Pass Regulators 30-899 30-900

By pass regulators must have a return line back to the fuel tank. It is advisable to use the same size return line as the feed line from the

fuel pump to be certain the return line can handle the same fuel volume as thepump output. If the return line is too small it will not be

possible to reduce the fuel pressure to the desired level.
This regulator can be plumbed a number of ways. It can be mounted ahead of the carburetor, in which case the normal fuel line is routed

through the regulator with a return line exiting the bottom of the regulator. It can also be mounted after the carburetor (behind the fuel log

or dual feed fuel line). If mounted this way, then the fuel line should be routed through the side inlet and out the bottom for the return line

to the tank. The other side port can either be plugged or can be used for a fuel pressure gauge or similar device.

This regulator has been factory set at 6.5 PSI with a certified gauge. If your fuel pressure gauge does not register within 10% of this

reading, you either have an incorrect gauge or another problem in the fuel system preventing the regulator from operating properly.

If you have any issues or questions during the installation process please call our technical service line at 270-793-0900.
