0154-172) included with your EP-10 sensor. If that document is missing
it can be downloaded free from the Lowrance web site.
Other supplies are not included unless otherwise indicated. Required
supplies include cable ties or other fasteners to secure the hose and
cable; an in-line fuel filter and any items needed to install the filter.
Two 1" hose clamps are included with the sensor.
We assume you already have a fuel line installed. The EP-10 was
designed to fit a typical 3/8" (9.5 mm) SAE USCG Type A1 fuel hose. If
your engine has different diameter hoses or metal fuel lines a section of
3/8" fuel line must be installed between the sensor and the existing
lines.
Recommended tools are a flathead screwdriver to tighten the clamps
and a knife to cut the fuel hose. If you need to route the sensor
connector through a bulkhead you will need a drill and a 3/4" drill bit.
Installation
Install one EP-10 sensor per engine. If you have multiple tanks, place
the sensor after any Y or T in the line feeding the engine.
The sensor should be installed vertically and as close as possible to the
fuel tank in an area where vibration is minimized. The housing has a
molded-in fuel flow direction arrow which should be pointing up. (See
the figures on the following page.)
Mount the sensor above the tank's maximum fuel level to avoid
accidental fuel leakage in case the sensor becomes disconnected.
Caution:
Gasoline is extremely flammable. If possible, drain the fuel line
before you start or shut any flow valves located at the tank. Keep
sparks and flame away from the work area. After installation
remember to clean up any spilled fuel.
Cut the fuel hose where you intend to install the EP-10 sensor. Slide a
clamp over the hose coming from the tank and push the hose onto the
bottom (inlet) hose barb.
Seat the hose flush against the sensor housing and tighten the hose
clamp. Attach the hose leading to the engine on the top (outlet) barb in
the same way.
