NEW Integrated pump sender combo!

Having just installed this piece, with some assistance, at the Tech Session yesterday, I then proceeded to put 75 miles on it and I must say, I was amazed at how novice-level of an install it is. My initial reason for wanting to install it was that my fuel gauge had stopped at the 1/4 mark and would only slightly fluctuate; a feat I attributed to a faulty sender, turned out to be another issue was a slightly disappointing moment, but it's a job that I would comfortably be able to add to my repertoire of roadside work I feel comfortable performing on the DeLorean.

On a storage-related note, it leaves the old sending unit location as a prime spot to siphon the gas from the tank for long-term storage.

I'm having a similar problem with my fuel sending unit. What did the "other" issue turn out to be? Grounding problem? I ordered Hervey's double-grounding wire and I'm hoping that solves my volt meter and maybe even my fuel gauge woes.

Has anyone experience fuel leak with this new pump unit? I keep getting fuel leak, especially when i do the hard braking or sharp cornering. I start smelling fuel so I open hood to find a small fuel leak around the fitting. I reinstall this unit multiple times. Carefully inspect rubber gasket, metal clamp and clean both fittings and gas tank opening. Press down pump (hard) while I tighten the clamp. It doesn't matter how much I tighten or lose, it still leaks every time. What am I doing wrong??? or do I have a defective unit? uggggg... I was thinking that $400 pump should be trouble free.

You don't have it installed correctly. The top of the clamp should be ABOVE the white plastic to hold the unit down against the lip of the tank. The way you have it, it should leak like crazy! When installed correctly you should not be able to see the rubber seal at all.

PS - Dracula's problem 3 posts up turned out to be a defective shunt resistor on the fuel gauge itself.

Everything Dave said. I found this part of sitting the pump and clamping it correctly a little tricky. Take your time and push that pump down and then clamp it.

Crappy picture but hope it helps.

Dave and Jimmy,
Thanks so much. It didn't leak like crazy but drove me crazy for several weeks. I feel so stupid now. Does this look right? After I reinstall clamp, I drove for about 30 miles including hard stops and sharp turns. I didn't see any leaks around the unit. I did smell a bit of fuel when I open the hood, but it could be from this morning. Oh, by the way, I can even close the cover now.
Thanks again.

I could have sworn it was an ACDelco/GM-esque style unit back when I first saw it in 2011 :P

I'm sure it was pretty easy installing this type in a Delorean, with their access hole in the trunk. Just recently had to replace one of these in my blazer. Wasn't fun to drop the gas tank out on the street, TWICE :/ Guess I din't clean out the gas tank good enough the first time and the pump failed after a month. So close to cutting a hole in the floorboard!

Wow, that is awesome! I just learned about this today. Granted my Fuel Pump and Sender work. Even replaced the pump/boot probably 3 years ago? And I'm pretty sure I'm going to get this ASAP. Wonder what vehicle this is from or if DMCH had a supplier build it. This is pretty exciting!

Anyone that has installed this have an original sender unit they'd be willing to part with?
My car came with the first "improved" one and I cant stand how it never reads full , stays at between half full and half empty forever, then drops 1/4 to almost empty.
