Hello,
My 87 Vert only has the normal fuel filter. If you want more specs on the car, et Me know.
Take Care and Be Safe, -John

Thanks for the restart of the thread, what we discovered was that there were complaints during the 85 and 86 model year, a TSB addressed it. some, not many 85 and 86 got modified. All the 87's have them from the factory and then in 88 the pump was changed. The problem being eliminated, no more dual filter set ups.

If ALL 87's have two filters...please tell me where the second one is.
I have only found the one filter above the convertible X-frame, beside the Cat on the passenger side frame rail about close to the front edge of the passengers door forward.
Any info appreciated. If there is another, I'd like to find and replace it!

You All Take Care, -John

right side of the car, behind the heat shield next to the y-pipe / downpipe, directly above the normal filter.

This is the location, but mine is deleted. Notice the blue hose. (return line).
