Fuel Lines & Hoses - Monaco Cayman 2005 Owner's Manual

The correct adjustment technique, with a full tank of fuel, is to start with the full adjustment screw
completely clockwise. This should cause the reading to be above full. Adjust slowly, rotate counterclock-
wise, until the full mark on the gauge is reached. The intent is to always adjust downscale rather than
upscale.
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 constant
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 provid-
ed 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 effi-
cient, 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.
