Title: Will this work to prime a Proheat heater?
Post by: belfert on September 25, 2011, 06:55:33 AM

My fuel line for my Proheat heater is nearly 20 feet of 1/4" fuel line.  I doubt the Proheat can pull fuel that far through a dry line.  My thought is to use a ketchup or mustard bottle to push fuel through from the tank end.

Will this work?  I assume I will have to crack open the other end to let the air out.  Any suggestions if I don't have a second person to close the valve on the fuel filter when the line is full?

The 'single handed' to bleed brakes is to pressurise the master cylinder using air from a car tyre, using a simple kit for the purpose that you can buy from an auto accessory store. With a little bit of ingenuity you could use the same kit to pressurise the fuel tank, then, working at the Proheat end, let the air out of the fuel line in a controlled way until diesel flows out.

Just fire it up and the fuel pump should bring the fuel to it . it may take 3 or 4 cycles to fire off

I have used an outboard motor priming bulb successfully for this purpose, permanently installed.

The generator was downstream as well, 2 for 1.

happy coaching!

I temporarily disconnected the fuel pump and connected it directly to 12 VDC after cracking the fuel line fitting at the inlet on the injector pump. When fuel starts leaking from loosened fitting, line is primed. Jack

PS: my line was about 10'

Won't I have problems with air in the line causing the pump not to move any fuel kinda like a regular diesel engine when it runs out of fuel?  I'm all for using the pump instead if it really works.

I used the same system as Jack when my 4104 lost prime, worked fine.
