Hey guys I was just wondering if I could reuse the Salvage fuel pump from the donor Dakota / Durango I got

I am dropping a 5.9 L Magnum from a 2001 Durango into a 1973 Dodge swinger in the process I am using all the OEM harnesses wires and even air conditioning system I have all the harnesses from the headlights all the way back including the PDC PCM and interior fuse box I would like to regulate the fuel going to my fuel rail

Edited for more information
I'm thinking just put it in a tank /cell Fuel and run it off there is there any problems with this setup

To do what? They are high pressure, IE EFI. The other thing, depending on what you are doing, is after you go to the work to mount that thing, yo are "stuck" with it, and if it goes bad, a replacement might not be cheap.

I went back and edited the post a little bit



I'm trying to run the fuel system setup wthl stock set up from the Dakota the engine comes from
I figure if I get a mounting me set up in the top of a fuel cell or tank I can just On mount it
On


I'm not gonna make it permanent also These
replacement pumps are less than a $100 for the entire unit

Are you going to mount that pump externally? If so not a good idea, those in tank pumps are intended to be cooled by the gas in the tank.
If you can mount it internal to the fuel tank, duplicating the factory install, it will be fine, OE fuel pumps are reliable and as you mentioned, not expensive to replace.
 
The reguator is built into pump.
Thats the large metal piece on top of the housing. Those pumps will run 175 psi when regs go bad. I have replaced regulators in the past.
Dont know if they can still be bought separately.

No definitely not externally mounted inside of a 15 gallon fuel cell is what I'm thinking access from the top OEM style mounting

I just priced A complete unit from Amazon for $70 shipped to my door
 
I'm running a 5.9L swap with a in tank fuel pump with no issues. I didn't do the swap but I do know everything came from a 01' Ram 1500. If my car were here I'd check for you, but, it looks to be the same pump that is in my fuel cell.
 
I figured somebody must have done this before or tried it I don't see why it wouldn't work .. If it aint too much trouble I could use a pic of your fuel cell set up
 
I guess I'm stupid (as usual) but I didn't see CLEARLY where you are going to run EFI or a carburetor?

Never done exactly what you are asking, but there isn't a reason in the world that wouldn't work as long as the pump unit is submerged.

Yes, of course it will work, great plan. Just make sure it does not interfere with your fuel gauge sending unit which I assume will still be used.

Yes! Of course you can, that is a good plan. The only concern you should have is interference with your in tank sending unit (assuming stock gauges). I like it

why can’t he connect his gas gauge sender wire to the sender terminal on the fuel pump?

Well, like I said if my car were here, I'd be glad to post a pic. But, its in jail at the body shop getting painted with no release date.

My fuel cell is 20gal and located in the trunk. Viewed from the top, a hole was cut out in the left corner, sealant applied and pump dropped in. The fuel line comes out the top, makes a 90* bend and through the trunk floor.

It looks very simple to mount, easy access to remove if needed. At least when the cell is in the trunk.

I will try to get a photo and provide an update when my car gets paroled. I hope this helps you out.

I might add that I'm running fuel injection with my 5.9, so I'm assuming you are as well with this pump. Otherwise I think you need an inline pump with a lower pressure rating. Maybe someone else can clarify that for us, but I think these are high pressure pumps designed for fuel injection.
 
OP on a side note, if you haven't done it already, be sure to write down the VIN# from the donor vehicle and tuck it away. At the very least the engine# which is a partial of the VIN#.

In the event that your pcm/ecm takes a dump and you have to buy a new one, they can get you the right pcm/ecm that matches up to donor vehicle. Because we all know that this **** last forever right.

Sorry for the diversion, now back to your pump issue. :usflag:

He can but might need that device that matches the fuel sender to the the gauge ohms.
Meter Match I think it's called.

They are high pressure pumps for EFI, and the Dakota pump should be the same as your 5.9 used in the first place.
 
I really wanted to use the OEM pump, so I spun up a threaded flange on the lathe to weld onto the OEM tank. If it won't clear the trunk pan, I'll recess the tank a bit. But I realized I'd cut the threads upside down (They're triangular with a 90 degree face) and then got busy so I haven't got back to it.

I'm thinking you should get back to it.
In while you're there spun me up one to let me know how much I owe you What is the ETA on that?
 
Gentleman yes I plan on using the EFI from the original Durango donor
so i left have the connections for the -dash cluster and ob2 port.
I'm not sure what gauges I will be going with..
Stock is definitely out of the question
Way too expensive to restore and use the OEM stuff
The fuel cell comes with a sending unit for a gauge..and if I chose to mount the Durango cluster I should be able to use the iem fuel sender I think.

Where were you 5 yrs ago when I had the donor in my yard for 3 weeks?
This is the best advice for anyone thinking of this kind of swap..especially if the car has the immobilizer like mine..
If this pcm takes a **** on me I'm screwed.
Is there anyway to get the vin number off the pcm? I have the obd port available?

Wish you'd have said that about 10 posts ago. It is IMPORTANT to understand "we aren't there." The only issues I see are these?

Dakota pumps will not be readily available forever. In another 10 years, if you need a replacement, might be touch. Might.

It will take some fabbing to install that pump in anything else except where it came from. I don't know where you'd get the pump mount in metal, does anyone repop it?

There are many generic EFI pumps available, and a little money spent might save you giant headaches in fabrication and later replacement.

How many miles is on that pump? It might fail a week after you get the car together.
