Titan Fuel Filter Heater – 12V DC – 50W – 4″ × 12″

The THF50-12 is a 50 W, 12 V DC silicone heater that straps around a spin-on diesel fuel filter and keeps the fuel in it from gelling, so the engine gets fuel on a cold morning. At 4.2 A it is the lower-draw option for smaller diesels, gensets and light towers. The Velcro strap fits metal filters from 3.75 in to 5 in in diameter and moves to the new filter at a filter change in a minute. Wire it through a fuse and a switch; switch it on 15–30 minutes before starting.

Size to your oil pan or hydraulic tank capacity, not your engine size. An undersized pad heats slowly; an oversized one can create hot spots.
