Hi does anyone know where I could buy a pre heater (been told its basically a pipe with a heater plug in it that's blanked off at both ends and fittings for the fuel line added) this is to work on a timed relay to preheat cooking oil to assist starting from cold.....I would be using this in conjunction with a heat exchange unit to heat the oil once started...thanks

Heat sinks are generally made of a large block of alluminium.

Remind me what your injectors are stuck into?

There's very little point at all in trying to preheat veg for cold starts as, by the time it's spraying out the injector, you will have already needed to force all the cold stuff through, with the crap spray pattern and the resultant ring gumming.

If you want to do it properly either twin tank with switch over valves, or get somthing like the webasto thermotop to preheat the whole head. But then you would need another fuel tank to run that anyway.

Again, your injectors are stuck into somthing that looks very much like a massive heat sink. If youre trying to overcome that with a small electric heater running off your 12v battery, I think you can see that it will be, well, disappointing.

Not heard of diesel or oil waxing in low temperatures?

Yawn....

Of course i have. But then that's an issue with the filter blocking, not the spray pattern on the injector.

Do you actually have any experience in this area?
