I need to replace the fuel pump on my Webasto HL32D diesel boat heater. Options would seem to be either an 82553B (out of stock) or an 85106B, howeveer none of the Historical Product Codes mentioned for these two pumps matches those on the original pump which are: Ident Nr. 114.592, Fabr Nr. 114098. Could you please advise if an 85106B, or other pump which you currently stock, would be a suitable replacement? Thanks in advance for your help. Robert

Hi Robert,

Point taken ... Webasto part number variations for their repair parts (and fuel  pumps in particular) can send well intentioned folk down a very winding path. The very short answer is that the suitable 12v replacement pump for your HL32 diesel heater is catogued on our website as 86115A ( which may come to you showing 85106B on the pump dataplate)

All Webasto fuel pumps from HL32 to present day have the same dose rate 'per click'  - then variation part numbers are given to the pump dependent upon, among other parameters -

the source manufacturer of the pump?

whether diesel/petrol compatible?

whether supplied with a new heater, or as a repair part  variations?

Electrical termination?
