Installing a second (bleed) line on a new oil tank

[pktaske]

I just put in a new above ground 275 gal tank to replace my old 550 underground which is approaching 20 years. Anyway, I'm about to run the copper line to the burner and I notice I have a bleed line coming back from the burner to my old tank. My question: how do I route the return line back into the tank? Through one of the 2" openings on the top? How do I adapt the 3/8" copper through this 2" opening?

thanks...

Drop the copper tube thru a compression fitting. The tube should extend to within ~3" of the tank bottom.

Be sure the lines are *well* protected from any kind of damage. Include required shutoff valve(s) on the suction line.

Although you could use the burner as a one-pipe system, running the return line will make for a better running burner.

Do I drill into the tank for the return line or use one of the 2" openings?

Ah. Use bushing in the 2" tapped opening.
