GASOLINE FUEL PROBLEMS/SOLUTIONS
1. Engine is hard to start or idles rough-
is problem can be caused by foreign
particles or water in the fuel system or a
blockage in the fuel supply which causes
a lean condition.
Check all fuel system lines, clamps, ttings and lters for
tightness. Check the entire system for fuel leaks.
2. e engine hesitates at intermediate speeds or fail to
obtain top rpm- Check the fuel system for possible leaks,
clogged fuel lters and/or malfunctioning anti-siphon
valve.
3. e fuel tank reads low and the engine is running
rough. e pick-up tube has possibly picked up some
residual water from the bottom of the fuel tank.
Pour dry gas into the fuel ll tting and ll the gas tank
with fresh fuel. Test run the engines to purge impurities
from the fuel system.
4. Fuel tank gauge not reading correctly/or not at all-
If you disconnect the fuel tank sending wire leading
to the dash gauge at the sending unit and ground it
momentarily with the key on the dash guage should
show full. Release the wire from the ground position
and the gauge should show empty. Normally this would
indicate the dash gauge is working properly.
item to check would be the fuel sender ohms reading
which is explained earlier in this section. Also, make
sure the sender wires and ground are securely fastened
and the ground wire is tight. Many times a loose ground
wire will cause a malfunctioning dash gas gauge or the
gauge needle moves in a irregular fashion.
