my 2006 thomas bus with cat engine keeps sucking the upper fuel filter dry and the engine kills bottom filter is full only code I read on board is bh-164 can you help me find problem. Changed both filters ran ok for fisrt route secound route it shut engine down again top filter runs dry
Sounds like a fuel line leak. Two possibilities. The fuel line/fittings or the drop tube in the fuel tank. That filter on the firewall is the fuel/water seperator. Find the vent hose hanging off the side of the tank. (sandwiched between the frame and tank) If it isn't sitting in the dirt on the frame rail have someone else put air (2 psi or less - use a vacuum/pressure gauge) in the tank through that vent line. If there is a fuel leak you will find it this way
Have had several vent tubes on the tank get plugged (mud wasp, road dirt) but the fuel/water seperator stays full for me. You will find a big vacuum on the fuel tank after engine quits. Loosten the fuel cap to find out. HF
Once you return to the point of the BHM164 (MID) - Press & release the button once - This should give you either a Parameter ID (Pld) or a System ID (Sld) ---- A PID should be a J1939 code ---- An SID Should be a J1587 code --Write down the PID/SID & #
Next: Once you have the PID/SID displayed - Press & release the button once - This should give you the Failure Mode Indicator (Fail/FMI)
With these 3 parts of the codes you will have: - which Computer - which System - What it doesn't like about that system's behavior.
I may not know the answer but I can usually find who does.
