    Ok, some of you know the drainback issues I and a few others have had. There are lots of LS setups with guys using a scavenge pump feeding the return through a billet fill cap with a -10 AN fitting.

    Has anyone here tried this? I think as we put the '13 back together, we might try feeding the drains to a scavenge pump straight back to a custom billet oil fill cap like the LS setup.

    Thoughts? Unlike the pic below, I would weld a right angle AN fitting instead of the straight.

    Returning oil to the fill cap via -10 line is exactly what i'll be doing on my low mount TT set up.

    I scoured the web for hours looking for a cap like you posted above, but the only one I can find is for LS guys.

    I will likely buy another OEM cap and drill/tap it for the -10 fitting.

    Also you could use a fitting exactly like the one you have posted above with a 90 hose end vs. welding a 90 to the oil cap. Would basically be the same thing.
