PTC Thermistor heater for diesel filer ?

I will put it on a separate circuit on 10-12 ga wire fused at the battery with a relay connected to the key switch .

Where will you get the necessary 25 A from, for long enough?

May I suggest you run it from a second starter solenoid, and run that solenoid from a timer. Reset the timer when the car is running.

I plan to run a diesel / veg oil at some point in time and need those temps to prevent gelling.

There are bimetalic switches rated at 16A, that can regulate as low as

PTC heating elements aimed at 70C are pretty rare, particularly at the lower voltage. Automotive crankcase and block heaters aim to keep things barely above zero, and are standardly mains-supplied, for use when vehcles are parked. 24V heaters (for truck battery systems) are fairly common, but again are aimed at lower temperatures.

Because PTC characteristics are not ideal, the regulated temperature will depend largely on the energy absorbed. PTCs are better characterized as constant power dissipators, rather than ambient temperature regulators, if the system is not closed.

A discrete sensor and heater might offer better versatility, while the ptc elements and hardware are researched.

Also, 150 F sounds kind of hot. Maybe you can add something else to the fuel so that you don't need to maintain so high a temperature. (Ethanol? Methanol?)

A lot of people are running diesel engines off of discarded deep-fry oil nowadays, so I'm sure there are some good solutions out there on the internet.

have you checked out

good references in this on using staight veggie oil instead of biodiesel

Serious error. All shortcuts have disappeared. Screen. Mind. Both are blank.

Yes I am plaining insulate the filter . Most of my internet "research" has revealled recommendations of a an optimum filter fuel l temperature of 150-180 for vegetable oil (WVO, SVO ). I was hoping that the PTC solution would but it sounds like they won't and I " A discrete sensor and heater might offer better versatility ( eg glow plug heater with furnace type - snap disc limit switch ) , while the ptc elements and hardware are researched. But There some 12 v higher temperature PTC s do exist out there ( used 12 volt coffee mugs etc , like those here -
