Troubleshooting:
A. Electronic Output: The sender has a transistorized output to prevent an ohmmeter from get-
ting a correct reading of its output resistance.
B. Fuel Only: The sender will not work correctly in conducting fluids such as water (it
will read above full all the time in water). One possibility is that when there is a con-
stant above-full reading there may be water in the bottom of the fuel tank.
C. Contact Centroid: Probably 90% of the return Centroid tests work okay on the bench. If
you have incorrect readings contact Centroid (telephone: 800-423-3574, or preferably, fax:
386-423-3709) with the symptoms. A short,"fill in the blanks" troubleshooting test is pro-
vided to test the sender. It is easier to find the problem that way than after the sender has
been removed from the system, since the problem is not necessarily with the sender.
Fuel Lines & Hoses
Make a visual check for fuel leaks at all engine-mounted fuel lines, connections and at the fuel tank
pick-up and return lines. Leaks in this area may best be detected by checking for accumulation of fuel
under the tank. Engine performance and auxiliary equipment is dependent upon the ability of flexible
hoses to transfer lubricating oil, air, coolant and fuel. Maintenance of hoses is an important step in
ensuring efficient, economical and safe operation of the engine and related equipment.
INSPECTION:
Check hoses daily as part of the pre-start inspection. Examine hoses for leaks.
Check all fittings, clamps and ties. Make sure the hoses are not touching shafts,
couplings or heated surfaces, including exhaust manifolds, sharp edges or other
obvious hazardous areas. Over time, vibration from the engine and road can move
or fatigue clamps and ties. To ensure continued proper support, inspect fasteners fre-
quently and tighten or replace them as necessary.
Fuel Filters
Three filters are used for the engine: pre-filter, primary and secondary filter. The reusable pre-fil-
ter and the primary filter are located in the engine compartment. The secondary filter is located on the
engine. Prime the fuel system when filters are changed or if the engine has run out of fuel.
Filter Maintenance Intervals:
• Change the primary fuel/water separator filter every six months or every 15,000 miles.
• Refer to the Manufacturers Guide for service intervals of the secondary fuel filter.
NOTE:
It is recommended to wear gloves and old clothing when working with diesel fuel. Avoid
getting fuel in the interior of the motorhome.
