Default Re: Fuel Tank Coil Rusty Wye Fittings

Being that the proper OEM part doesn't seem to be available I have been looking for some substitute fittings for the fuel coil rusty joiners. (Dodge supplies an incorrect plastic 1/4" Wye fitting contained in a MB part bag.) The unequal leg divider fittings are not a common configuration.


I located some vacuum fittings that have angles that should fit. I don't know the pressure rating of the fittings.

I'm also not certain what the fuel pressures are at the fuel cooling coils. Being that they're on the return system the pressures may not be very great. The fact that the fittings can be quite crusty and not leak also supports that the fuel pressures are not very high.
