1998 Dodge Dakota 3.9 L Fuel System Diagram
This message is for DustyK and any others (pbjar1) who replied to my original post:
"Repairing/replacing fuel line at pump - '97 Dakota 2WD"

"in line fuel filter 1995 Dakota V6"
Unfortunately I never got any practical/useful replies on my original post but, having now made the repair using brute force methods, I can report the following:
Aside from the hassle of removing the very thin-walled plastic tube that connects the fuel pump outlet to the metal tube that runs along the chassis forward to the engine compartment, the Dodge dealership wanted ~$45 for a new one and it was to be special order! I would never recommend this route.
The best approach is as follows:
1) Remove the left rear wheel and place the axle on a block.
2) Realize that the space (about 10:00) behind that left rear is difficult to access, and lighting will be scant. If you can morph yourself into Mighty Mouse, that would be a huge advantage.
3) For the lighting problem, I do not recommend an incandescent work light (sparks = explosion); us a B&D snakelight or similar.
4) Release the clip from the fitting at the pump outlet and pull off the tube. Using a sharp utility knife, cut the tubing from the metal line along chassis, remove this tube and make sure the exposed metal ends are clean of residual (plastic) tubing pieces.
5) Understand that - sadly - Dodge decided to make the OD of the metal pump outlet be 0.375" (~3/8"), while making the OD for the metal tube that rides along the chassis 0.320" (~5/16"). This disconformity is bizarre and senseless!
6) Go to a hardware store & purchase 1' of 5/16" high-pressure line, 1' of 3/8" ID hp fuel line, and a 3/8" nylon barbed hose mender.
7) Attach the mender to both hose pieces (you may need to hold the end of the 5/16" hose in scalding hot water to press over the 3/8" mender). Secure these ends w/ a hose clamp on each side of the mender.
8) Place the other end of the 3/8" hose in scalding hot water w/ a bit of dish detergent (for lubrication) for 2-3 minutes. Slide a small hose clamp over it and quickly and with aggressive turning motion, fit the heated end onto the pump outlet. Note that this outlet has a raised collar for attaching the fitting you just removed. The presence of this collar will require an agonizing effort to force the 3/8" hose over it and all the way in to the pump body (~7/8"). If you don't reach the pump body w/ the end of the hose, pull it off, reheat/lube, and try again. Once you get it, slide a hose clamp up near the pump body (over the outlet) and tighten. The best tool is a nutdriver w/ 12" long handle. (Once you try this, you'll see exactly why I suggested a tool like this.)
9) Slice a small hose clamp over the 5/16" end of the hose and and slide the hose a few inches over the end of the metal tube that runs along the chassis. (You probably won t really need to heat/lube this part of the hose.) Slide the hose clamp over this joint and secure.
10) Start the engine and check for leaks.
Finally, I'll answer the question that seems to have been floating around on what became of my post. NO, positively and assuredly, there are NO in-line filters on the Dakota. The one and only filter is inside the fuel tank, and that brainless Chrysler design is why it's such a colossal chore to replace it (should you ever - God forbid - need to). You gotta remove the tank!
Which points up a possible modification to my steps 6&7 above, You may choose this unfortunate event to use, instead of a nylon mender, an actual in-line fuel filter and get 2 birds w./ one stone. In this way you splice the 2 hose pieces and enhance the filtration.
Hope this helps.
