Russel fuel filter adapter fittings? Good or not?

[Bowtie racing]

Do these russel AN adapter fittings work as supposed with corvette fuel filter/regulator ?
Or are there any other choices ?

They work great but here are the part numbers for the better fittings. The push on style have a habit of coming apart, these actually thread together and do a much better job.



RUSSELL PUSH-ON EFI FITTINGS (SCREW IN END CAP)

-6 AN Male to 5/16" SAE Quick-Disconnect Female - Blue 644110 - Black 644113 Return for filter shown

-6 AN Male to 3/8" SAE Quick-Disconnect Female - Blue 644120 - Black 644123 Feed from pump

-8AN Male to 3/8" SAE Quick-Disconnect Female - Blue 644130 - Black 644133 - Feed from pump in -8

The correct fitting for engine fuel supply is


6 AN male to 3/8" SAE quick-disconnect male 640940 and only comes zinc plated.

Fragola also makes a black push-on but I can't vouch for it--491989BL for a -6 x 3/8" male. But I think I would go with the Russell stuff that has the screw in end cap--in fact, I did. :)
