OEM Service Manual Please Call

We strongly recommend the use of a service manual to familiarize yourself with the various components and procedures involved with this installation. Please note that some of the original clamps, hoses and hardware removed in the disassembly process will be used in the installation process. These instructions have been written in point form and refer to illustrations. Please follow these step-by-step instructions and illustrations carefully.

NOTE: These installation instructions are broken up into 2 sections. The fuel pressure regulator is set at 60psi and configured for rising rate. Due to variances in weather and altitude you must verify pressure is at 60psi when craft is running. To adjust fuel pressure see page 6 of these installation instructions.

Section 1 outlines the installation process for the complete kit on all 2008 and newer Sea-Doo 260, 255 & 215hp models. The kit is configured for rising rate at 1 to 1 with a base setting of 60psi. The supplied vent fitting

WILL NOT be used. To adjust fuel pressure setting see page 6 of these installation instructions.

Section 2 outlines the modifications for rising rate configuration and how to adjust the base setting. To adjust fuel pressure setting see page 6 of these installation instructions.

Should you choose to configure the kit for static fuel pressure replace the barbed fitting on the regulator with the supplied vent fitting.

- Fuel Pressure Setting Instructions & Guide -

The fuel pressure regulator is set at a static 60psi. Due to variances in weather and altitude you must verify pressure is at 60psi when craft is running. In the Rising

Rate configuration pressure is raised at a ratio of 1:1.

Fuel pressure increases 1 pound for every 1 pound of boost.

1. Hook craft up to flush kit.

2. Start craft’s engine and allow to idle.

3. Start water flowing to flush kit.

4. Hold adjustment screw using a 3/16” allen wrench.

5. Loosen jam nut using a 9/16” combo wrench.

6. Increase fuel pressure slowly rotating adjustment screw clockwise. Reduce by slowly rotating counter clockwise.

7. Tighten jam nut.

8. Rev engine up 2~3 times and allow to return to idle. Verify gauge is reading desired pressure.

9. Turn water off.

10. Turn engine off.
