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.

FWIW.

These 10mm Y’s look promising? They’re brass, but the nickel plating should make them B100 compatible.

(have we determined the ID of these fuel hoses?)

Possible maybe.

The configuration of the OEM fitting is a bit odd. Even the "straight leg" isn't really straight. It has a slight offset.

Refer to the pics in post #1 and in post #26.

The straight leg vacuum fitting I found might not really fit, but may if the hoses allow enough give.

Check the 1/4" Dodge part comparison to OEM that Theodore was kind enough to provide in post #26.

My guess is that 5/16" might be a bit loose, but will clamp down to seal. The 3/8" may be snug, but the hose should push on.

The fitting which you found will probably fit if a loop of hose is used for the one leg. Another option is to use long(er) hoses on each leg and place the fitting further away from the OEM position. That won't affect flow enough to matter.

I haven't tried a MB dealer using my VIN, only the Dodge dealership who provided the incorrect too small 1/4" diameter, and incorrect equal leg Wye fitting. The MB dealership is a bit of distance away for me.

Thanks for searching. The quest continues.

One of the reasons that I have yet to replace the 2004 crusty looking fittings was that the access and parts change looked to be a bit of a pain.

One answer to the problem is to use 3 ea. long(er) hoses and route the fuel hose out to a traditional Tee fitting. Alternatively, it looks like either a Wye or Tee fitting should install on 2 legs with no problem. A long hose loop can be used for the leg that doesn't align properly.
Added:
If OEM isn't possible, and the long hose loop method is necessary, 3/8" barb Tee fitting are more common locally than are Wye fittings.
Additional reflection:
It may make sense to install an equal leg Y fitting in a backwards facing orientation. That should allow the loop hose to fit into the space available and maybe use less hose.
