41 ford car stock gas tank sending unit - recommendation
Any strong recommendations for a new gas 4ank sending unit?

Yes, don't expect any of the reproduction units to work with the original gauge.

Re: 41 ford car stock gas tank sending unit - recommendation
All the 6v electric tank units (35 or 6 to 55 or 6) have the same top, only the float arm is different. You can usually take the top off and clean the points and a non-working one will come back to life. I posted a chart in my MISC photo album that comes with a NOS unit as to how to bend the arm if yours is missing. I can send you a higher resolution copy as a PDF file if you PM me your email address if you need or would like to have it.

Re: 41 ford car stock gas tank sending unit - recommendation
Veeder: If you still have the old unit, check the float for hairline cracks that allow gas to seep in and give false readings. Do a SEARCH on GAS TANK SENDING UNITS. It's interesting to see what others have encountered re: repairs.

Re: 41 ford car stock gas tank sending unit - recommendation
fordor: Thanks for posting about that aftermarket sending unit. Were the gauge readings between FULL and EMPTY accurate also? Plus, do you know how much gas was left in the tank when the gauge registers EMPTY? Thanks.

Re: 41 ford car stock gas tank sending unit - recommendation
I really didn't care about 1/4, etc, just E & F. When at E, it would take about 16 Gal + or -.
BTW I couldn't find a Ford sender on Yogi's website |

Re: 41 ford car stock gas tank sending unit - recommendation
Well here are my plans
1 The tank is in tough shape purchased a new (bob drake) replacement and aftermarket sensor. I did take the old sensor out cleaned it up (filed points) and seems to be working well. SO I hope to get the tank boiled out and sealed then stored with the original sensor for some person if they ever want to make this perfectly stock. The issue I have {all though not critical) is the new gauge has a resistance range of 11.5 ---101.36 ohms ( Straight resistance based sensor technology). The stock ford gauge is apparently between 10-73 ohms however it is not a simply design but very interisting it was fun understanding it. I did some tests today and I think if I place a 70 ohm resistor to ground from the new sensor it will give me the best average accuracy across the entire spectrum of the tank. HAS ANYONE EVER DONE THIS IS THE QUESTION?? |

"I did some tests today and I think if I place a 70 ohm resistor to ground from the new sensor it will give me the best average accuracy across the entire spectrum of the tank."
The 1941 OEM Ford gauge does not work on the OHMs principle and will not give accurate readings with any modern aftermarkt gas tank sending unit that operates on the OHMs principle. However, please do let us know how your 70 ohm idea works oput. I do hope your idea works although I don't know what "average accuracy" means. We need 'real time" on the spot accuracy.

Re: 41 ford car stock gas tank sending unit - recommendation
I found by trial and error that the replacement sender in my car needed a 7 ohm resistor (not 70 ohm!) to get the gauge to read accurately at empty.
And then it is only accurate near empty, not full range. With full tank the needle stays pegged until tank is about 3/4 full, then starts coming down. But as mentioned above, accuracy is not important up there. I only care about accuracy when I have to start thinking about how far to the next gas station. |

Re: 41 ford car stock gas tank sending unit - recommendation
It's good to know how many gallons of gas you have left in your tank when the needle reads 3/4, 1/2 ,1/4 and E because it provides you with an estimate of how many more miles you can drive,especially if gas stations are few and far between.
Having your gauge read accurately gives peace of mind. Who prefers a gauge that reads 1/4 tank left one minute and then the next minute the needle drops like a rock to E and your running on fumes? |

Re: 41 ford car stock gas tank sending unit - recommendation
Fortunately, I found an NOS sender on ePay for my '41. Was a bit pricey but now I can rely on what the gauge indicates.
Otherwise, your mileage may vary...

Re: 41 ford car stock gas tank sending unit - recommendation
Anteek, Smart move. Whatever you paid for that 1941 NOS unit, the price was right.
It was worth it. They are very hard to find. Last edited by 19Fordy; 12-30-2021 at 11:03 AM. |

Re: 41 ford car stock gas tank sending unit - recommendation
@JayChicago: Out of curiosity, did you place the 7 Ohm resistor in series with the gauge or in parallel? My gut instinct suggests placing it in series. Thanks!

Re: 41 ford car stock gas tank sending unit - recommendation
Messed with a variety of resistor configurations today it appears that a resistor in series of a value between 2.2 --2.5 ohms does the trick. I do think that each car will end up being slightly different. I'LL do a bit more testing within the next couple of weeks to confirm. However for my car it's looking like 2.3 ohms in series does the trick.
