Fuel Pump

[Ricker]

Well great, I think my fuel pump died. Probably because of having to hit the key 20 - 30 time to get the pressure back to start the engine after the car sits for a week or two. I have one of those aftermarket units with the integral level sensor, but I can't find the replacement anywhere. I do not want the existing system. I liked the new one, well if it worked. Where can I find one, recommendations? THANKS!

I checked with Delorean TX and they do not have this unit in stock. Not sure when it will be back in. Checked with DeloreanGo and they don't carry it. But I think I remember that the unit was from a GM car. Anybody know which one? Or do I need to just go back to the original design/units? My problem with that is the stud inside the fuel tank is too short for some reason and I can't bolt down the plastic "sump". What's everybody using? Thanks!

V-band clamp is used to secure the housing to the fuel tank opening. Here is the GM/Delphi pump module:

Delorean Industries has complete kits.

Do we know which one Delorean TX was selling? I'm just trying to keep costs down but more importantly the least amount of work. I think mine looks like the AC Deloc one. What kinda flow do these things put out?

Their module may not have a direct OEM equivalent.

Delphi FG0089 works too:

You'll need to bend-up your own float.
The DMCH box will run it but the gauge won't be as accurate.

Did you do any of the pressure checks in the other thread?
I wouldn't touch the pump unless I couldn't hear it running when jumped on at the RPM relay. Or it was making terrible noises or something like that.

What I did was disconnect the engine feed hose right before the check valve at the fuel pump (12" from the fuel pump). Put the end of the hose in a mason jar and cranked over the engine. The pump buzzed but no gas flowed. I'm assuming I should have gotten some gas in the jar. I also noticed the much different sound the pump was making from before. Also, the fuel pump is almost 9 years old. Maybe it has been going bad for a while and that is why it sometimes takes so long to build up the pressure/flow????

So, I did get the Delphi FG0089 unit (including the electrical connector but no hoses) from Partzilla for $176.20 delivered. It went in with no issues. Well, there were a few plastic "tabs" I had to take off. This may remove the warranty but was needed. It even accepted the electrical connector from the old Delorean TX unit in there from 8 years ago so no electrical work. I let the car sit for 5 days and before it took a number of key turns to get the car started. Not this time, started right up. I think/hope it solved that problem also.

Good news! It's a roll of the dice in today's world with many part manufacturers outsourcing and quality suffering. Fingers crossed all is good with your new pump.

Your fuel gauge will not work properly, unless DMCH changed something with their sender setup.

When my DMCH pump failed many years ago I also switched to the Tahoe pump. I was able to get the gauge working by bending up a new float arm out of a coat hanger. I found the senders to operate within the same ohm range, but inverted to one another.

If you still have the old pump housing I would gladly purchase it off of you. They fit a Hellcat pump very nicely
