Fueling & Injection - Fitting type at fuel filter?

I'm trying to build a fuel system for LSx swap into older car. Using the Camaro LS1 fuel filter but I don't know what type of fitting is used on the threaded end of the filter. Anybody know?

Here are two examples. I'm guessing it is one of these styles?

Nobody knows? I think it is the one on the right side of picture.

Somebody here has changed a fuel filter and seen the fitting. Is it the one on the right, or not? I've ruled out the one on the left.

Assuming it is the same as the return line on the t-block of the f-body fuel system, it is a 14mm x 1.5 o-ring fitting (Russel Part # 648070 [14mm x 1.5 O-ring to -6AN] is the correct adapter for the t-block to convert it to -6AN). So the fitting on the right in your picture.

Good, so I do have the right style then. Thanks!

Yes you do.

I thought the feed line had 16MMx1.5 nuts from filter to t-block & the return was 14MM X 1.5?

I thought the feed line had 16MMx1.5 nuts from filter to t-block & the return was 14MM X 1.5?

That could very well be the case...since I no longer have my Camaro, I can't verify the sizes. I know for a fact that the return is a 14mm x 1.5, but never had to replace anything on the feed side.

Thank you.

Just in case anybody pulls this up in a future search, the parts to adapt to -6AN are the TPI fuel rail adapter fittings, ACCEL p/n 74730. Earl's has similar parts.
