Brian Conway 264 Report post Posted October 11, 2018 Anyone purchased a fuel sending unit that you are satisfied with ? I am in need of a new unit and would like to hear about a fuel sender w/part number and vendor ? Sender for a 1969 20 gallon tank without warning light. Thanks, Brian Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted October 11, 2018 I purchased two Scott Drake fuel senders and they were both garbage, didn't work. Then I purchased a Spectra brand fuel sending unit through Summit. It doesn't look original, but works perfectly. Dorman also make one, but not many places stock it. 1 RPM reacted to this Quote Share this post Link to post Share on other sites
Brian Conway 264 Report post Posted October 11, 2018 Just the info I am looking for. Could you be a bit more specific ? Spectra makes several models so the model number you purchased would be great. Thanks, Brian 1 RPM reacted to this Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted October 11, 2018 Oh please do list the part number of the Specta unit! Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted October 11, 2018 This is the sending unit I purchased about a little over a year ago. So far it works fine. https://www.summitracing.com/parts/sgt-fg86b/overview/year/1969/make/ford/model/mustang Napa Auto Parts also sells it. It's repackaged in a NAPA box.

I suggest you throw that plastic pos float away and put an original style brass one on it if you plan to keep the car. Quote Share this post Link to post Share on other sites
Brian Conway 264 Report post Posted September 4, 2019 No I have not installed the Spectra so can't provide a performance report. I did buy it, FG 86B, but got side tracked with possibly a rebuilder, Bill @ Desert Classics, for my original C9WF-F. Having the trans in my 65 rebuilt and so on. Sorry Brian Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted September 4, 2019 My original brass float was filled with fuel so I ended up using the plastic float that is installed on the Spectra brand sender. Since then I've noticed NPD sells reproduction brass floats. Quote Share this post Link to post Share on other sites
bigmal 225 Report post Posted September 4, 2019 I have had two new aftermarket brass floats fill with fuel. I have heard it is to do with the Australian unleaded fuel but have nothing to confirm this. I know of others who have had the same issue. Next time the float sinks I will try a plastic one.

Rcodenewf 44 Report post Posted September 7, 2019 I installed two SPI units in my 69 fastback and both failed with sunken plastic floats. Then i went to scott drake..they sell two different ones..the cheapie and a stainless steel one. I bought the stainless steel unit several years back and it has been fine.

danno 128 Report post Posted September 9, 2019 I recently bought an ACP FM-EF002, I would guess from National Parts depot. I hooked it up electrically before installing in the tank and with it the gauge would not cover the entire range from E to F. I had to bend the high and low stops on it, and I got it to register the entire range. I changed the floats ( as described below) and am now testing it to verify it reads F when the tank has 20 gallons, and will check it just above E to see how much it takes to fill the tank. This one came with a brass float, and I have had 2 of those brass floats fail. My other car (99 Contour) has a type of plastic material with no air inside, so I am trying that. I doubled them up and wired them to my Mustang arm. I know the float worked for 20 years in my other car, so I would guess another 20 will not be a problem. pictures below. I got the floats free from a local self serve junk jard. Make sure to test yours dry, outside the tank with a ground wire and a signal wire to connect it to the car. That way you can easily verify it will register the full range on the gauge. Quote Share this post Link to post Share on other sites
Pizzeck 10 Report post Posted September 19, 2019 Sorry to be so late weighing in on this - I'm just getting to the storage unit to look at the box that the unit came in. I used a unit manufactured by All Classic Parts (ACP) and sold by Mustangs Unlimited which has worked well going on 5 years now. The part number is FM-EF002SS. They also supply brass floats - FM-EF005B. Unfortunately it looks like Mustangs Unlimited no longer carries the item but ACP has numerous dealers that can probably get it. Closest to me are Classic Mustang of Houston and John's Mustang Parts and Accessories. Quote Share this post Link to post Share on other sites

Brian Conway 264 Report post Posted October 31, 2019 Installed the Spectra FG86B in my 20 gallon, non warning light, 69 Mach 1 on Oct. 10, 2019. Been keeping track of gas gauge and ohm readings. Anyway some numbers: dash gauge reads Full and both sending units are sending between 9 and 11 ohms. Dash gauge reads 1/2 and both sending units are sending about 22 ohms. Dash gauge reads 1/4 and the Spectra is sending 31 ohms and the C9WF-A is sending 26-38 ohms. Dash gauge reads Empty and the Spectra is sending 46 ohms. The OE sender C9WF-A is sending between 52 and 59 ohms. The expected ohm range should be Full=10 and Empty=73 pg. 15-03-03 Shop Manual. FWIW the 46 ohm= 4.5 gals in the tank and the 53-59 ohm readings had 3.5 gals in the tank. Brian Quote Share this post Link to post Share on other sites
Mike65 475 Report post Posted October 31, 2019 Brian, do you need another gas gauge, I might have mine laying around in a box if you want it. Quote Share this post Link to post Share on other sites
Brian Conway 264 Report post Posted October 31, 2019 Mike I'd certainly welcome a 69 gas gauge. At the very least I could see how it works and do some bench testing. Gas gauge for a mach I w/tack is different than the standard dash ? Let me know what I can do to help this along ? Thanks, Brian Quote Share this post Link to post Share on other sites
