Gone but not forgotten
I forgot to take pictures of this set-up when I pulled the engine, but I figured I should still publish them to show people something they may not be aware of.
When I first encountered the second filter, it had me, as well as a few others, scratching our heads. One mechanic said he had seen them on C4 Corvettes before, but his employer said he hadn't, nor had my mechanic.
It wasn't long though before I found the reason for the second filter on the return line.
Evidently someone had the same problem with my '87.
Pictures! The fuel feed line filter is on the left, the return line has the second canister-type filter, pictured on the right.
Shots of where the filters were mounted to the right front frame rail, below the "suitcase."
