Engine/Transmission (1998.5 - 2002) Fuel module fittings

[CStewart]

Finally got the fuel module fittings I had made up for mine listed in the classifieds under basement enterprises if anyone is interested.

That is sweet. I bet they cost a lot less than what dodge wants for their fuel module... . When I broke mine, I had to use copper tubing and a 1" pipe nipple and cap to rig up a fitting. I posted pics a while back. There was no way I was going to pay $100 for a fuel module from the junk yard.



How do you have the plumbing set up?

 

[CStewart]

I used 3/8 brake line and compression fittings on mine. Here's some pics.

Pics

For some reason they won't let me post the same pic in more then one thread even if I rename it. Here's a link to the other thread with pics.

Very nice

I think a lot of members will be glad to pay whatever your asking when they find out what DC wants for a new module. Way to go

I've been out of the loop on this just a little bit however; I know one fitting is the feed line and the other is the return line. I recall feed back suggesting we not "spit" the return back in the bucket due to thermal asspects of the "warmed" returned fuel.

Can that asspect be changed when we do this wonderful modification that you have made so properly easy to do ?



Thank you

Return line

On my truck I still have the return line going back inside the fuel module just for insurance during cold weather operation. Thats the only reason I can think of for having the return run that way. When you you redo your fuel module you can run your return where ever it works best for you. I know that in a gas engine keeping the fuel cool can really help performance wise and prevents vapor lock problems and such. In our diesel trucks I'm not sure if thats the case, I know fuel gelling can be a problem but I don't think there would be a problem with warm fuel unless maybe its easier to get entrained air in it when it circulates back to the tank.

Actually......

I understand that diesel fuel is used to lubricate and cool our VP44 injection pumps. Most diesel engines have specs on maximum fuel inlet temperatures. In fact many diesel engines use fuel aftercoolers to remove heat from the fuel before dumping back into the fuel tank. I do not know the specs on the 5. 9 but I imagine 140 F would be about the max inlet temperature.

From what I have read a well lubricated, cool, VP ia a happy VP I thought about monitoring the inlet and outlet temps in order to gain a better understanding on temps and the VP44. Has anyone else done this?



I agree gelling can be a problem and I plan to connect the fuel heater in my FASS, possibly with a bypass valve and fuel cooler plumbed in for summertime use. I would like to see temperature data before going overboard though. Auto manufacturers sometimes skimp on things like this to save $$$$. When we bomb our rigs boderline can become Uh Oh quick :{

The more I read about this stupid fuel tank module the more I think about just getting a 60 gallon in a bottom fed bed tank and completely removing the stock fuel tank module and tank. Now I think the delivery side would be all fine and dandy... but the VP44 would have to push the return fuel UP above the bed... is that going to kill it?

Is there anyone that sells a complete module upgrade kit?

There are a couple of us working on fuel temps and the VP. I diverted my return to the tank filler line to get it away from the pickup so the pickup does not get hotter and hotter fuel and the return dumps hotter fuel back at the pickup.



I would REALLY like a set of the cnc fittings. I think you said they are on the classifieds on the site. $400 is rediculous.



On the VP temp thing we are experimenting with getting cooler fuel to the VP.

On the VP pumping up hill. Leave the OEM tank for the VP and you put a lp to pump it up to the bed tank. Feed out of the in bed tank.

CStewart,



I looked uder all the classifieds and did not find the cnc fuel module fitting parts. Could you pm me and I would like to get a set from you.



Thanks,



Bob Weis

CStewart, are you out there?

Anyone know how to get in touch with member CStewart? I've PM'd and emailed but no word from him yet. I need to get a pair of these fuel module fittings and soon so I can get my rig back on the road.

 

[DLausche]

Chris just got back to me and is going to fix me up with a pair of his fuel module fittings. I guess he has been out Elk hunting and just got back. I was overly anxious and I appologize if my post appeared immoderate.

Let's see:



Elk hunt or WORK!

Deer hunting or WORK!

Fishing or WORK!



hummmmm, tough one, lol.



Chris sent me my fittings and they have not arrived, he just emailed me the package he sent is sitting back on his porch (hurricanes have something to do with it?). I had an inkling he was out hunting, and I was wishing I was, so I felt patientance was a virtue.



It will get here when it gets here,



Bob Weis



Wishing I was out fishing!

CStewart,



Are you still in the aluminum fitting business? Looking at all available options. .

Fittings

I usually get them made up as needed. I sent you a PM on the specifics. If you have any other questions let me know.

Hi Silver_Ram. If you do go this route you should be pleased with Chris's fittings. I'm pretty sure you have the newer style fuel module so you will only need one of these fittings. I bought two and ended up only needing one because I have the newer style module on my 99. I used the auxiliary fuel supply fitting for the fuel return to the tank.
