One thing I hated to do was to stand over the heater and look down the intake pipe to find out how fast the oil was flowing. During a search on waste oil heaters I found on YouTube a guy who built a Sanders design, he bought a needle valve with a window from Roger Sanders. He also posted he paid $50.00 for it. With a pic of the valve I began another search and found a valve made by Lube Devices and the part number was N102-02, It turns out that Grainger carries them under their number 1U795, they go for $34.95. This little guy makes setting the heater so much easier. I recommend highly.
I live in the UK and none of the listed suppliers will ship to me, has anyone any ideas? i have searched and cant find a UK supplier or any that will ship to me, any help would be much appreciated
thanks
