The supply line from the dosing pump to my diesel heater (Espar) is about 10 feet long and is a tiny nylon tube (2mm ID, 3.5mm OD). This tube is pressurised with diesel during opertion and still under tank pressure when not operating.
Is anyone else concerned about having what appears to be a very fragile plastic tube under fuel pressure in the engine room?
Has anyone used a different tube? I get the impression that Espar wants a very small ID tube - perhaps to ensure that any air bubbles get swept through. The smallest fuel hose I can find is 3/16" ID (4.8mm).
I wondered about encasing the Espar tube inside a rubber hose for protection along most of the run.
