im gonna make my own from a jaz cell and isolate it from the trunk. anyone use one with the sending unit and still be able to use their stock gauge? also read while surfing ford r and d bought 50 and said they were crap. 36? or so bladders leaked, foam broke down after 3,000 hrs(?) and clogged up stuff. i called fs and they said they rebuild them at a cost of $800. forget that. that should come with a kiss.
