DP42 Fuel pump versions are not directly compatible and may cause fueling issues and poor comnbustion or heater failure in the future. Each pump version has a specific measured dose or fuel per pulse.

The Webasto UK recommended replacement Dual Top RHA pump is: Webasto Dual Top fuel pump 12v | 9019418A | Butler Technik

This version has a specific fuel dosing quantity suitable for the following Webasto Dual Top Models:

Webasto Dual Top fuel pump DP40

  • Dual Top RHA 100
  • Dual Top RHA 101
  • Dual Top RHA 102
  • Dual Top Evo 6
  • Dual Top Evo 7
  • Dual Top Evo 8 

Please note - 12 volt only.
