oil drain line, what size fittings?

[warren91]

Hi,
I bought your return line for a stinger header and was wondering what size the fittings were for the drain line. I am currently swapping out for an efr and the t3 drain isnt the right size. i found an adapter for the efr but it is 10an male and i was wondering if you knew what adapter if any i would need to get it to work. thanks!

Our lines are -10 so that's not an issue. The EFR has 38mm bolt spacing on the return flange so you should be able to slot the holes in the T3 flange and bolt it on. If you want to buy a new flange though, you can do so and thread our line directly onto it, though you'll need to remove the 45 degree AN to 1/2" Pipe thread fitting we supply with the line. Ideally you'd find a 1/2" NPT flange for the EFR so you can use that 45 degree fitting, or use the -10 flange you discussed above, and then purchase a 45 degree -10 to -10 fitting to replace the one we supply.
