Hello,

I’m desperately looking for a part for my car. I own a unique vehicle called a UMC Aeromate. All Aeromate’s came stocked with Dodge Caravan engines. Mine is a
1994 Dodge Caravan S.E., 3.3L, V6.

Recently the fuel rail started leaking so I took it to my local shop. After digging around they couldn’t find a replacement and my local salvage yards had nothing. After an extensive search online I can see they were recalled, but I couldn’t find any parts other than the injectors. The original part number was 4554109. I believe a 4554108 is also compatible.

Does anyone possibly have a contact that might have a NOS 1994 Dodge Caravan S.E., 3.3L, V6, fuel rail, in stock? Also, does anyone know of another model fuel rail that might fit? I know a 93 Chrysler New Yorker is compatible, but couldn’t find one of those either.

Thank you for your time and help.

Welcome to Allpar. That was the latest Mopar part # and it has been discontinued for some time now.
I would be surprised if any dealer had one in stock, but stranger things have happened.
If it is leaking fuel at the end caps where the transfer tube runs between the front and rear bank rails, there are o-rings inside there to seal the tube. The transfer tube has to 'float' as heating, cooling and vibration events will need some movement. Trying to cement it with a rigid adhesive or brazing it won't work as it will eventually break and leak again.
Many shops will not attempt a repair on obsolete fuel components as the liability for possible fire and casualty is too great a risk. I have seen tutorials on how to repair them (maybe here on Allpar), but the success rate is unknown:

Around that time (not sure the exact year) Chrysler switched to a "return-less" fuel system.
The early v6s have a variable pressure regulator on the rail, and the fuel returns to the tank from there.
The newer V6s (from 92, 93, 94... sometime around then) put the regulator in the tank, it was not variable, and there was only one hose leaking to the fuel rail.
So although the two systems are basically the same, the fuel rails are not compatible.
Which rail do you have on your car? Finding the newer "return-less" rails is easier than the older type. Particularly used.

Yeah, I was afraid of that.
I had a hell of a time finding one about 4 years ago. Cant imagine it's gotten any easier.

I have no other advice, I'm afraid. Except maybe to scour the net and junkyards.

I had the same problem with my 94 Caravan and I took the rail apart to clean out the "O" rings. Found a pipe tap at a pawn shop
and taped the ends so as to fit right angle pipe fittings from the hardware store, solder the threads in and connect between the two
rails with high pressure fuel hose. Has worked a charm for two years now. Hardest part was getting the solder in the brass fittings
to the stainless rails to seal.

If you find one in a yard it will be in same condition as yours ! Did you see my note of the 16th ?

No because they moved the pressure regulator around on the fuel rail and the accessory drive components are moved around year to year
