    My VIN:    11596

    Just a couple quick updates. This weekend I got the car running and everything is working great. I only drove it far enough to get to the gas station so I could fill the tank up with fresh gas, then went straight home. Almost as soon as I got back to my garage I put the car up on jack stands so I could do a total brake overhaul which might take up to 2 weeks to complete since I'm having DMCMW plate the calipers.

    The low fuel light came on as I was driving to the station and I added about 11.5 gallons fuel, so the low fuel light comes on at around 2 gallons remaining.

    When I got home with a full tank, I jumped the RPM relay to see what the pump sound like, and it's so quiet that I could hear the fuel rushing through the lines on the engine louder than I could hear the pump.

    More updates once I get to do a full shake-down of the car!

    That's a good sign. Did you get a chance to check the pump current yet?

    Oops, forgot. I will either tonight or tomorrow. Should I measure the amps with a meter directly on the pump with the rpm relay jumped, or is there a better way for an accurate comparison?

    You want to pull the fuse and measure the current across the two fuse socket terminals. You will need to jumper the RPM relay for this test.

    DON'T put a current meter across the pump or you will blow the fuel pump fuse and or your meter fuse.

    Using Dave's method I measured exactly 7 amps. Key off, rpm relay jumped, measuring across fuse 7 terminals.

    How does that compare to OEM?

    Edit: Derp! My car is stock. Just measured 6.2 amps using same method with stock setup.

    7 to 8 amps is normal. It will draw a little more when the engine is running and the battery voltage is 14 volts. You also get a little difference depending on how your primary pressure is calibrated.

    There are no original unused Fuel Sending Units available. At delorean.com they sell a new metal one to replace the original plastic one but some people have complained over many years that the new metal one hits the gas tank bottom and doesnít fit quite right. The gas tank is plastic and is some what flexible thus making the distance from bottom to top slightly different in some cases.
    Other people have had the fine wires inside the original Fuel Sending Unit break and some one like John Hervey (http://specialtauto.com) offers to fix it.
    My original still works but Iím some what annoyed when the gas tank is low the fuel sloshes around and gas gage goes down to 0 and back up to 1/4 and back to 0 and back up to 1/4.
    I have to wonder with this new combined unit will the gas gage still go up and down and up and down when the gas is low in the tank?

    According to the thread in vendor announcements, there are electronics in the new one to prevent exactly that.

    And how long before you offer this but 100 % stainless?

    So... Four months then till he starts telling people he has "shipped hundreds of units all over the world with no complaints", and that Steven's pump is junk?
