System for vapor recovery without formation of fluid blockages includes a vapor source, a fluid collection tank for collecting vapor, and a vapor recovery pipe extending between and fluidly collecting the vapor source and the fluid collection tank. The vapor recovery pipe slopes vertically downwardly from the vapor source to the fluid collection tank so that vapor flows into the fluid collection tank. The vapor recovery pipe has an elongated cross section, and a direction of elongation of the cross section extends substantially vertically. The vapor recovery pipe is engineered and is installed in such a manner that the vapor recovery pipe resists bending in a substantially vertical plane and allows bending in a substantially horizontal plane. Accordingly, the vapor recovery pipe according to the invention can be installed without surveying equipment, overcomes surface irregularities, and by resisting bending in a vertical direction ensures that no fluid blockages are formed along the length thereof. The bending of the vapor recovery pipe in the horizontal direction allows for the pipe to be installed around curves without the need for curved joints or couplings.
