Assuming you do not want to hack a hole in the trunk:

Hope that helps. Think I forgot to mention removing panhard bar, but it's kinda obvious since it's in the way.

Re: fuel pump replacement

The design of our sending units does not lend itself very well to a pass-through without quite a bit of modification. Since the hardlines on the sending unit go across the tank and down the front, you have to do a lot of hacking to the hatch area to make it possible. Now you can modify the sending unit, but you also have the chance of introducing leaks if you've never made flared ends before.

Dropping the tank is a pain, no question. These cars require you drop the rear end and exhaust to get enough clearance. You can get away with just dropping the passenger side of the rear, but it will make things more difficult. Definitely give yourself a day or two if you've never done it before.

Re: fuel pump replacement

Dropping the tank and doing it right is not that hard, took me 3.5 hrs and was finished, it doesn't take a day or two...

Re: fuel pump replacement

I was being a bit generous with the time. If someone is a bit new to the task, its better to budget more time and be done early than to go over what you expected and be up the creek.

It took me about 30 min to drain the tank before I even got to crawl underneath, then had to run to the part store to get new clamps because my old ones were rusted.

But I'm still with you on this one J91; dropping the tank is will still be quicker than cutting up the trunk the right way.

The cutout method can be done, but to do it right will take more time than dropping the tank.

Re: fuel pump replacement

Here is a video on cutting. If you want to remove the whole unit, if you want to just cut and remove make sure there is no fuel in the lines and replace it with fuel hose.

Re: fuel pump replacement

I cut the hole in mine. I dont have the facilities to drop the tank. Took me about an hour or so. The hardest part was putting hose over the lines with all the hose clamps.

I agree dropping the tank is probably the "right" way to do it. I cut the hole in mine and don't regret it. I know this debate has been beaten to death and some people get real defensive of their preferred method. For me it's a matter of choice but whichever way you go you will need the appropriate tools, time and plan your work. I agree that a previous poster could do in in 3 or so hours under the right circumstances. I would allow for more time. Rusted/seized bolts, differences in exhaust, available tools (and/or help) etc can all be a factor in how long it takes.
