Go mechanical, the kind w/o an isolator. As long as you use a nice braided stainless line and steel fittings properly sealed you won't have a problem with leakage. It's not dangerous like gasoline leaking into the cab, but it would still make a mess in a hurry.
Autometer says the electrical job shouldn't be used with the Cummins but I don't know why. Maybe it rattles the sender apart?

I use electrical, and they are maybe a shade cheaper than the mechs. They are Dynotune guages, one is square and the new one I just added is round. The square I used in my 2nd gen and she's still working flawlessly today. Its about 1"x1 1/2" and mounts nicely in the bottom left of the guage cluster. The round I just mounted in the tripple pillar. The rounds you can get black or white faces with chrome, black bezels. PM me for a link if you want to check them out.

When we were testing for our electrical gauge we also ran into a few failures with a standard duty electrical fuel sender. The Cummins is the only engine it failed on. It took over 20,000 miles to cause it to fail though. When it failed it still read ok, but anytime there would be a big change it would cause the numbers to go all over the place and then it would settle down.
Evidentally the pressure senders work off a wiper inside the gauge. This is the part that fails.
We switched to a severe duty unit that has the wiper blade isolated. This is the same sensor they use on Siesmigraph machines or however you spell that. We have not had one break yet, they are a little more expensive, but that was ok as long as they don't break!
