Always good products
As always works perfectly. I've done 20 or so cars trucks ect with their parts and never had an issue. This 5/16 was for the throttle body of my mud pro ATV (also got a 3/8;for the fuel hat) swapping over to AN line and doing away with the plastic junk connectors and ribber line.

Decent just oil the line before connecting
Make sure you have the mail end of the line that's going into the fitting oiled up or it will cut the o-ring and make sure that lock nuts tight as possible and I would put some fuel safe flood seal on the male half of the fitting threads decently made but still soft metal I'm not too happy with evil energy quality or their company and quality checks I should say
