We have systematically reduced 17 years of data from the Voyager ultraviolet spectrometer (UVS) archives, from which we have obtained 431 spectra that place useful limits on the diffuse far-ultraviolet radiation field between 912 and 1100 Å. We observe a large range in brightnesses ranging from upper limits of 30 photons cm^-2 s^-1 sr^-1 Å^-1. The diffuse background is correlated with the integrated TD-1 flux near the line of sight but shows no correlation with N(H I). We place a 1 sigma upper limit of 30 photons cm^-2 s^-1 sr^-1 Å^-1 on the level of an isotropic extragalactic continuum. We have modeled and characterized the observed heliospheric H I and He I emission lines in the outer solar system as a function of heliospheric distance, apex angle from the direction of the inflowing interstellar wind, and time as specified by subspacecraft solar intensity. This modeling adequately reproduces observed intensities over a range of heliospheric distances of 15-50 AU, for an unrestricted range of look directions, and for a 12 year period (covering 1 solar cycle).
