Technical Looking for a specific fuel filter

I'm looking for a metal type fuel filter with 5/8 threads on both sides So that 3/8 hard line can screw into it. The early vette type is for 5/16 line, anyone know one for 3/8, line.been searching and not coming up with anything. Please help

 

AC GF-90

 

Thought V 8 inthe late 60’s 3/8

 

It seems the GF90 has 1/8 inch pipe fittings,and then you have to get adapters to run to the three eighths line.

 

This might get you started,

Plus, I have this one, measure 5/8" on both ends, metal construction, same length as the AC GF90,

FF3504/C481

look at AC 05650677 says 3/8 on both ends

 

Try one for a 65 Vette. 396/425 GF416. I think they are direct thread for 3/8 hard line.

 

I'll be running by the part store before work. I'll let you guys know.

 

The only one that crosses over is the GF90 and will be here at 3 o'clock, so hopefully it's correct.

 

Those EFI filters are not for normal inverted flare fittings, they are for a special flare that takes an O ring.

 

The gf 90 filter showed up and its got 1/8" pipe threads so you would have to run adapters to go to 3/8 lines

 

Plugged in your sentence and got a result from 2015

and one from 2005

Looks like this is a tough one. I gather it's the one place where they engineered a bit of flex (rubber or braided) rather than have hard line on each side. Can't think of another reason but servicing.
