    53005 is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Good piece I bought this part, not knowing whether it would fit or not, just going on memory, I thought it would and guess what, it did. I searched the internet for 3 days and finally decided to try Jegs again, you see, I have a big block Mopar and though it is a little narrow in width, it fits perfect. I wish the description said bb Mopar.

    What is the thread on the hose barb that threads into this filler neck? I want to change mine to an AN fitting instead of the hose barb?

    Asked by: Darth4308
    These are the fittings sizes; two 1/4" NPT intake manifold bypass fittings, a provision for 1/2" NPT sensor fitting, 1/8" NPT x 5/16" hose barb for the overflow.
