I want to install a diesel heater in my Renault master mk3 from 2016. After alot of searching i found out (from eberspacher) that this van has a fuel return line i need to tap into, BUT it needs a fpr valve. Because the return line has a small amount of pressure and the diesel heater and pump expect 0 pressure. Eberspacher sells a kit with everything included but it cost the same as the Diesel heater itself (€100). It feels weird paying that much just to hook it up to the van's tank. So now i am thinking about using an auxiliary tank. Just unsure about placement, underneath the van or inside a door or on the rear door (with a metal jerrycan). Just don't want a diesel tank inside the van in case of spillage or fumes. If any ideas (or pictures), i am al ears!
