Diesel tank plumbing ?

G.Fields · Dec 31, 2011

I have to come out of my electric pump, go up 6ft, 20ft across a beam, and back down about 6ft to my hose/nozzle. I am planning on using PVC, but got to wondering if the glue would hold up to the diesel. If it will sweet, but if it wont whats th enext cheapest thing to use.

I would use standard black pipe

I have had 3 300 gallon tanks plumbed together to a pump with galvinized pipe for over 30 years with no problems.

Of Course steel is better. But, I have pumped many thousands of both diesel and Gasoline through PVC, Glue never failed even one time. To begin with I had reservations, but it worked perfectly!!

Just a thought. By going up over and back down as you described there will be an air trap in the highest part of the piping.IF your pump is somewhat inefficient you may have a problem getting a prime. If so it may be necessary to put a verry SLIGHT!!!,air pressure on the tank to raise the fuel up to the 20 foot run of pipe. Two and a half to three pounds of pressure will be sufficient. Bear in mind every square inch of your tank will have whatever pressure you apply.Thus 2.5 lb X 144 Sq. in. == 288 pounds load on each sq. ft. of tank surface. Use extreme caution.

Just a thought, assuming you're using fuel hose with a wire braid inside and a metalic fuel nozzle, there will be no "static" ground in your piping system if you use PVC

I would use black pipe. PVC would work. But there is the danger that it could be broken. If have seen that happen on backup generators. Also at the point where you go over the beam. You could add a check valve. It would keep the fuel from draining back into the tank.

Steel is expensive, but fuel is more expensive, and it costs more to do something and then do it over again right.

His pump is still mounted right on top of his tank per the original post.

I understand that. But he is going up six feet. I have seen fuel drain back into a tank through the pump.
