Ticking Sound in Moho

[grovelander]

In my '85 345, I hear a ticking sound coming from the rear roadside corner when the power is on. Anyone know what this is? Thanks.

GL-in my 90 345 the water pump/motor is located rear roadside and its noisy untill the system is pressurized.

Likely your original electric fuel pump. Else might be your electronic tag axcel controller pinging the electric brakes. If its the brakes, you'll hear it on both sides. Look under the unit in front of the fuel tank and you will find fuel pump.

Both the water pump and air pump are located in that area above the floor. The fuel pump is centered just aft of the tags.

You have twin beds?
You hear this inside?
When hooked up to power? or engine running?
Does it ever stop while power is on?

Is hot water heater trying to light?
Or rear gas heater pilot?

Thanks, everyone. This does seem to go away when the water system is fully pressurized. Appreciate the help.
