Like I say,the tank needs to be dropped. Several reasons why. First,the
bundle of wiring in the harness is zip tied to the main harness in several
places. Access is poor.Of course one could just YANK and YANK till the zip
ties gives way.Number two reason the tank needs to be removed. The rear
floor vent is attached directly over the gas tank.removing this vent
requires the tank to be dropped.Two #2 phillips head screws attach this
vent from underneith the floor. Also the parking brake cable and shift
linkage needs to be disconnected,most likely, to manuver the vent ,out.A
large diameter hose is attached between the vent and front heater. The
rusty hose clamps need to be removed to take  this hose out and preserve
it. Both were in good condition of the two BA6 units I removed.They can be
reused. Need to get all the parts , and removing the tank is necessary.No
big deal here .This is an oportunity.A good time to reseal the gas tank and
add fiberglass coolant tubes and powersteering lines( both avaliable in
myebay store).Here comes an insatllment on the cover for the BA6.Look
out!!!
