63 swc with 1964 engine . It has a black ac fuel filter marked gf 99, The catalogs for ecklers, corvette central list a gf 90 as the filter available. Will the gf 90 substitute for the gf 99 ? The silver repros are 18 to 20 dollars , the black ac gf 90 is about 50. I suspect tank debris due to intermittent fuel problems.

GF90 is the correct filter for your car

My car came with the correct black filter GF-90 ,[1964,L76]. I didn't want to pay that much money for the black filter so I bought the silver one , I figured I would just paint the silver one black. It wasn't that easy, the silver one had the correct 1/8" pipe fittings, but the case diameter is 1/8" larger, the original clamp was too small and the silver one would not go into it . The silver filter came with the correct larger clamp for it in the filter box. Also where the clamp bolts to the intake manifold , I had to grind down the metal on the new clamp so it would fit [ it was too wide] . Just so you know ahead of time.

My recollection is the GF 99 is a Corvair Spider fuel filter. I think it has a nipple on it for a return line. You can use the 99 if you solder the nipple shut.

The GF 90 is correct for your car.

Mike, The gf99 does have a soldered return nipple. Lovesvettes, I may get the silver gf 90 and Thanks for the installation tips. Since I cleaned the teflon out of the carb inlet fitting (As per my other thread ? )it has run fine so maybe the old black ac will stay .
