Look at NFPA 31 for more info on piping. NFPA 20 references it in the appendix as an alternate source. Burying it isn't prohibited as long as the proper materials are used. No mention of encasing it. The questions that come to mind are; what piping materials were used, what are the environmental regulations concerning encasement of fuel transporting lines.
Typically with pre-fabbed pump houses the lines are run along the floor and anchored. This is typical for site built as well. Craig L.

I'm looking at a project where the fuel supply and returns lines were put into a shallow trench and routed from the fuel tank to the engine. They then grouted the whole trench to make it level with the floor. So now the fuel lines are inaccessible except at the two ends. Is this a common practice? It is allowed by NFPA 20? NFPA 20 does not specifically address this type of scenario that I can find. I think I'd like to have the lines accessible. Maybe putting checkered plate over the trench but without something to justify it the project is going to want to duplicate the existing condition.
