Very useful write up. Thanks!
My problem was that I had to prime 2, 3 or even 4 times before my engine would start so after researching I found various posts on the matter. This post, however, is perfect in order to take all the necessary steps in order to drop the tank and disassemble / assemble the module.
I 've got 115.000 km (that's around 75.000 miles).
I decided to take the risk and save me some money so I didn't replace the fuel pump but just the fuel pressure regulator (which was the actual problem in my case) but thought I should replace the 2 strainers as I would have to drop the tank and they are cheap anyway.
It took me 3 hours in total from which I spent a good half hour trying to get the freaking plastic nut back on
Had I just replaced the fuel pressure regulator it would have been much faster as I wouldn't have to take the module off the tank.
My jeep is as stock as it gets but I didn't have to lift it in order to drop the tank. I laid on my back and worked on the bolts etc pretty easily. I also didn't bother emptying the tank once I had dropped it as it looked very clean anyway and I got lazy finding a canister etc. Putting it back on was not that hard as there was about 1/5 of petrol in it.
The j bolts were quite cooperative as well.
Now, I don't wear gloves, goggles etc when I do this kind of work but if I have to do it again I will definitely wear goggles. My jeep is pretty clean under there now as all the dirt is in my eyes
I got the strainers (airtex) and fuel pressure regulator (SMP PR318) from ebay. I live in Greece so it took a while for the parts to arrive and it was a bit difficult finding sellers that would post to Greece but it all worked out fine.
Next project, replacing the valve cover gasket (I hate oil leaks). It hasn't arrived yet...
