Would love there to be another way although in the motorhome the pump is mounted underneath and is barely noticeable inside although I wouldn’t operate it if there was anybody in a tent outside.

Gav, do you think changing the fuel line diameter will affect the performance ? I want to replace some of the plastic fuel line with rubber hose (4.8mm seems to be what is used) between the tank and pump which wont affect it but pump to heater may ?

I remember seeing somewhere on Youtube that there is an issue if you replace the hose after the fuel pump with something more flexible as the pulse of fuel expands and contracts the more flexible hose where full pressure needs to go to the injector - research before changing the line. I didn't find any issue with the line provided.
