Mercury MerCruiser Service Manual page 375

A 1.5 m (5 ft) length of hose will work for most applications. A longer or shorter length of hose may be used to meet your
specific needs. Example: To ensure the hose is visible from the helm of a cruiser would require a much longer hose than would
be required for a runabout. The smaller diameter hose works best when using a long hose to reduce the amount of time and
fuel needed to become visible in the hose.
IMPORTANT: All components must be fuel rated and must be inspected regularly to ensure the tool is in safe working
condition.
Supplies needed:
• One‑gallon fuel can (collection tank) with separate vent.
• Clear hose (the hose can be from 3 mm to 9 mm [1/8 in. to 3/8 in.] diameter). The smaller diameter hose works best when
using a long hose to reduce the amount of time and fuel needed to become visible in the hose.
• Appropriate sized barbed hose fitting.
• Fuel pressure adapter (90‑803135) from Mercury or other equivalent adapter.

In the following example a hole was drilled through the cap. The cap was tapped according to the size of the barbed hose fitting
being used. Sealant was applied to the threads of the barbed hose fitting and the fitting was threaded into the cap. The clear
hose was connected to the barbed hose fitting and the fuel pressure adapter attached to the other end of the clear hose.
