Please walk me through the steps to unclog my furnace oil line. I have seen the process, but not performed it myself. I have a Burnham furance with a Beckett pump/injector. I ran out of oil and now am clogged.

Check out this walk through:

If you still have a problem, it could be that the clog is in the filter, which you can replace.

Let us know if this helps.

HI,
I also would like to suggest putting a can of "dewatering" liquid in your tank. It will remove any water condensation, that might be built up, and can remove some of it from your filter. I think it might sometimes be called a "conditioning additive" for the oil tank.

How does wiki how work? All I get is a blank page from your link and the same if I type the question in the box.

Strange. I see it as a link to an article.

Try this one Google results link... the article I'm referring to is the first link on the list:
