Default Second Fuel Filter only in 1987?

I post this after searching like crazy for any info about the second fuel filter I believe is only on the 1987 C4...couldn't find anything other than a couple of listing on parts sites.

Any 87 owners replaced this? It's listed as a fuel return filter w/gasket, Delco part #GF62 (replacing GF62N), which is expensive, also available as WIX #33271.

Just curious what it does, exactly, as there is only 1 opening on it, and whether it should be a regular maintenance item. Astounded at the lack of info on the 'Net about this part...

cheers

If I remember correctly, it was an addition installed mostly post production at dealerships to eliminate noise generated from the fuel lines on cold start-ups. My 86 has one....not planning on changing it anytime soon....it's probably been on there for a LONG time.

Thanks for the reply, interesting info! Particularly interesting that you have it on your 86, www.acdelco.com lists the only car it's ever been used on as the 1987 corvette...

Default 1987 fuel filter replacement

Car has been sitting 8 months with battery removed. I want to replace fuel filter before putting on road. Do I need to relieve pressure on fuel pump ( install battery, remove FP fuse and run to stall) or has sitting for this length of time allowed pressure to be release so I can just replace fuel filter???

Very unlikely to still have pressure.
Time to re and re
