Webasto Dosing Pump.

[Brian422]

From new my Diesel Webasto Thermo Top C has used, according to it's profile,  a DP2 Dosing Pump.

 

I understand a Diesel installation should use Dosing Pump DP 30.2.

 

I would be grateful if someone would advise on the differences between the two pumps and should I replace the DP2.

 

Regards and Thanks 

Brian.

The Thermotop Evo uses a pump which is much quieter and operates at variable speeds, with a much higher pulse rate than the ThermoC when at full belt.

If your pump works, keep using it until it doesnt, then replace with the recommended one.

Being curious I looked up the price of a genuine Webasto DP30 fuel pump.

It’s almost £200!!!

Here is the link if you want one

Thanks for reply but I'd found listing on butlertecnik.

 

Really want to know whether there's a requirement to replace a little used DP2 with a DP30.2.

Assuming you have been running the system for a reasonably long time and it works fine without using an excessive amount of fuel, how will changing the pump make it work better?

 

When I fitted my Webasto heater (a few years ago) I called Butler Technik with a couple of technical questions and they were very helpful, they could probably answer your question, why not give them a call.

 

That said, I am pretty sure Matty40s also knows a lot about Webasto’s so I would happily trust his advice.

Does it work?

If it ain't broke, why would you want to fix it?

Well 3 posts have said that now, and it sounds like sense to my

I get the if it's working leave alone.

My query was more about understanding what are the differences between the two pumps?
