Pony Car Dialysis

The patient presented with kidneys this damaged after only 400 miles since the latest (in-line fuel filter) kidney transplant. This is the patient’s 4th kidney since 2009. The kidney original to the car was a tiny mesh that was the size of the inside diameter of the tubes at each end of the filter, and was problematic probably for the life of the car. It caused me all kinds of grief when I didn’t know it existed while driving it my senior year of high school in 1986. My dad retrieved the car and cleared the mesh, without showing me, then took me out for a spin to show me how much I didn’t deserve the car.

32 years from that drive with my dad, and the patient needed a new gas tank. Ghost dad has been discouraging this tinker, but I’m going to do it anyway. The old tank came out easily enough. Things were pretty clean. No real issues with rust. Just cleaned out and replaced the old rubberized stripping. The patient is lucky, as the original stripping hadn’t been laid all the way around and tended to roll up onto the tank rather then seat under it.

Old and new gas tanks. The old has a sludge mix of rusted grit that continually grows from the rusted inner walls. The drain plug was fused in place from the inside. More than a year ago I siphoned the tank, but that didn’t really effect the heavy silt- it sounds like a gallon of wet sand and pebbles when tipped back and forth.  The fuel sender had quit working long before she came into my care, so the gas gauge didn’t operate. The connective rubber section of gas line to the engine was rotten out as well.

I laid strips of rubberized caulk under the tank to seat it firmly, put in new screws, reconnected the goose neck to the gas cap with new rubber hose & clamps & gasket, and put in a new section of gas line down below.  And a new fuel filter up front in the engine bay.

Tomorrow I’ll head over to the local garage that carries non-ethanol gas and fill up my cans, treating the gas with Archoil to stabilize it. If there are no leaks, and the fuel gauge works again; then she will stretch her legs. Getting rid of the silty tank should cure her of many of her performance issues e.g. low fuel pressure at speed making choking rpms, and choking on whatever bad bits were sliding past the filter (nothing too bad as the jets are still clear).

update: The new gas tank and connections were all fine, so I took her up Emmigration Canyon on Halloween for speed trials on the back bit of “flat” road off the summit and she ran like a whole different car- quieter, no hesitation, no bogging down when pushed; just a clean and smooth response all the way through her full range in each gear, and falloff was just as clean.
