Default Fuel Tank Coil Rusty Wye Fittings


The fittings supplied by Dodge and MB may not be correct. Check for proper parts before ordering.

Thanks to theordore for the info.

last week on my T1N and I found this post. Ordered Dodge # 05133920AA. It showed up today, so I pulled the original damaged part (Attachment 103032)

and was disappointed to discover that it's not going to fit. The replacement is a 1/4" fitting, but the original is 3/8" if not larger (Attachment 103034).

There also very different in shape (Attachment 103033).

The replacement is definitely not flexible enough to accommodate the difference in angle.
I thought you'd like to see this so you don't count on a part that's going to leave you stranded when the original gives up.
The question is: where do we get an actual replacement part? I waited 9 days for this worthless thing.

Sorry for any misinformation about parts, but it's what I was supplied from the Dodge dealership.

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.
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.

JB Weld will seal the hole shown center in the picture [in other thread], and the other hole in progress up by the white dot.

Please let us know if the removed part is 5/16"... 3/8" or some other SAE equivalent size.

Anyone want to buy some brand new, unused OEM packaged dealership fuel parts for their T1N Sprinter?


If it is 5/16" (Reported to be 3/8", but 5/16" still might work.)




Jegs carries some parts.

Every Jegs web page contains this note. Be aware.
"Some parts are not legal for use in California or other states with similar laws / regulations"

This picture shows the possible alignment for 2 ea. legs.
The original text/thread starts here:

Today while I was working under my Sprinter (wheels blocked, with jackstands and floor jack in place) I noticed some rusty fitting parts on the fuel cooling loops. I did some searching because I thought I've seen some parts diagrams of the fuel tank, but these weren't included. They look pretty nasty so I want to replace them before failure.

I suspect they are check valves. - Edit: Only because they appear to be larger than a regular fitting. - That is a guess. [That guess was wrong. They are Wye fittings. Refer to post #11.] Anybody know what they are for sure? Part number would be appreciated (again, post #11). Probably worth inspecting if your Sprinter lives in the salty Northeast like mine does. On a happy note, my fuel cap still looks pretty good. vic
