I have an Air Top EVO40 Webasto heater (marine) which needs a new fuel pump.

Part 1324533 was last fitted 5 months ago. Not working now - old diesel. What does "without damper" mean? Is this the correct part? Thank you

If your Webasto Air Top EVO 40 heater is a 12v or 24v this fuel pump would be suitable.

A fuel damper uses a diaphragm to regulate and smoothen the flow/pulses of fuel and compensates for a drop in pressure as the pump operates. It is not always necessary to have a fuel damper.

An alternative fuel pump with a damper can be found at https://www.butlertechnik.com/item/Webasto/heater-Fuel-Pump-Air-Top-2000-STC-or-Thermo-PRO-9024802A/5F9
