Finally found an excuse to do the swap in the Dakota, and after reading just about every swap thread out there I have going into my '93 3.9 Manual AX15 truck
'98 5.9 with the harness and all accessories
Dakota Pan
Flywheel
New Clutch pkg
OBD1 5.2 PCM (I know not ideal, but it is supposed to work and can be changed out later)
Crank Position sensor
and (I think) most of the other pieces I will need
I'll keep the AX15 for now, which saves a couple of bucks, saves me from trying to find the information I would need on driveshaft changes, and will answer my curiosity about who's right - the guys who say the tranny will blow the first day and the ones who say it will be fine.
The question I do need answered and for which Google is letting me down is what to do with the fuel system.
The '93 has a return system and the '98 is no return. I come up with three options (4 if you count 'just put it together and see what happens.)
1 - a return regulator - this seems relatively easy but perhaps spendy. Prices run from ~$65 to ~$200 for a regulator and I'd still have to sort out placement and connection. If this is even a realistic option.
2 - A fuel pump for a 96up Dakota - Though it looks like this will fit, I am not sure how it is regulated. If it is managed by the PCM, this is obviously not an option.
3 - Pick up return fuel rails from a '94 - the problem is that the system pressure on the '93 is supposed to be 35-45 pounds and on the '94 should be 44-54 pounds. If the '93 pump and the '94 regulator will supply this, it's my preferred option.
Any help will be greatly appreciated.
