The follow is my experience in replacing the fuel pump using the non-LR part number listed in the Tech section - Parts Cross Reference . This is for a 4.0 ? ?97, ?98 & ?99 D1 (different part numbers are listed for ?96 4.0 & the earlier 3.9). This is a really easy low tech job and about as easy to access as anything on your truck. It cost me just under $100 for all the parts and an extra 10 minutes to take apart the assembly to put the new pump in.
*Normal Disclaimer: I take responsibility for what I do on my truck, you do the same. This is a great and easy way to save quite a bit of coin and get a high quality pump w/ a lifetime guarantee; however, it is not a genuine LR part. Take your time and don?t break anything or you may have to buy a new pump assembly!
Notes:
- have a fire extinguisher on hand
- it?s easiest to do this w/ a ? tank or less, but can still be done w/ any amount of fuel in tank
- the (numbers) below correspond to pictures
* What you need before you take anything apart:
- New fuel pump: MASTER E3270 ? ask for pump from ?96 Chevy Impala V8 SS
- New pump filter: MASTER FS22
- ?? Fuel injection line: ~6? (note - regular fuel line isn?t flexible enough for the spring loaded assembly)*
- 2x ?? fuel line clamps: note ? fuel line clamps, not regular hose clamps are recommended
- Fuel pressure gauge: if you have a Disco you should have this in your toolbox
* I originally tried to reuse the accordion fuel line from the pump to the top of the assembly but I could not get the pump side that originally pushed onto the 5/8? barbed end of the old FP to seal on the ?? straight connection of the new pump even w/ a clamp (See pic).
