Re: fuel sending unit bob drake
I didn't install mine yet,and glad that I checked it first with a multi-meter,against the Henry sender.The resistance readings of the Drake sender are not the same as the 47 merc sender.It might work if we could find an aftermarket gage,that is compatible.The reverse engineering for these repop parts,must be done in china also.

Re: fuel sending unit bob drake
I don't understand how you can measure resistance on an original Ford fuel sender. It uses a bimetalic strip and with a multimeter should read as near zero resistance when no voltage is applied. With voltage applied, the strip heats up and the points opens up, then the strip cools off and the points close again. Depending on the lever position, the dwell of its closure is more or less (more when the tank is full). The same is repeated at the gauge.
I don't have a Drake sender, but if it is made like the Ford sender, it can be adjusted. Remove the cap and you will see a knob which raises or lowers the tension on the bimetalic strip. I adjust mine so the gauge reads empty when the float is at the lower end and don't really care how far off it is when the tank is full. Those old Ford sensors (and the new 2010 fuel sensors) aren't that accurate in any event. And with age even the 80 year old NOS sensors have lost some elasticity. |

Re: fuel sending unit bob drake
Here's the sad story on the Drake sending unit. It does not work period.
The signal it sends to the dash gage is let's say...hmm Chinese...the dash gage doesn't understand Chinese it only understand English. That's as technical as I can get. I did my usual flailing of arms and screaming at the Drake tech guy and even though I had cut the arm to fit my tank ( per the instructions ) they fully refunded my $$$$$$$$$. This sender is sold by lots of suppliers with and without the Drake logo so beware. As Kube says the orig response was...." really we've sold thousands ".... blah blah. The big Canfield Ohio swap meet is this weekend and fuel tank senders are on my 'to find' list......there will be some there. Charlie ny |

Re: fuel sending unit bob drake
Remember, original sending units will not fit in Drakes new tank unless hole in tank is enlarged.

Re: fuel sending unit bob drake
I bought a gas tank from Drakes, but used a sending unit from Mac's. It is right on - full is full, and empty is empty. When I hit empty, I have about 20 miles to go before I run out of gas. Not sure who makes the ones for Mac's, but mine works great.

I have a drake sender in my '50 Convertible and it's right on the mark. Been in there 3 years now with no trouble.

Re: fuel sending unit bob drake
Although I am not sure who Dennis Carpenter's supplier is, the sender I bought from them for my 55 F100 works great.

Re: fuel sending unit bob drake
I have a Drake sender in my 37 and it works fine. It didn't work at first, but I found a bad solder joint at the top post of the sender. After a re-solder job it worked fine.

Re: fuel sending unit bob drake
Original senders don't change resistance like the drake sender --an ohmmeter won't test an original sender for it's accuracy -- just that the heater coil is good and that the contact points are making contact.

Re: fuel sending unit bob drake
I used the millivolt scale on the multimeter,and that's how I got the different ranges of readings.Is there another way to compare these senders?I don't want to take everything apart,after finding that it doesn't work.Thanks Meant to say MILLIOHM scale
