Okay, installed a 65-68 Mustang 16 gallon tank and have installed a new float (brass) to combat my gauge reading E constantly problem-the plastic float was cracked. Well I put about 2-3 gallons in the tank and it still read E. So I put 5 gallons in making the above 7-8 gallons and it only read 1/4 tank on the gauge. Am I missing something? Is my ground not good enough--where have people grounded? Or is there a mod that I need to do with the float arm because its not the original tank? Let me know; its driving me nuts! Thanks
-If I adjust the float how should I do that and do it to read correctly or so it leaves me 2 gallons when it reads E? and if that is the problem? -Secondly,And if I am fine, will the gauge read full when it is actually full? Beginning to Read only at 5 gallons just doesn't seem correct to me. -Anyone else with ideas/suggestions/ thoughts on all this?
Okay, I fully understand the basics of not running out of gas, but it seems like 3-4 gallons is a lot for that. As it stands the gauge reads 3/4 or just over when the tank is full and lapping at the top. To read correctly, which direction would one bend the arm (or whatever) to make it read correctly? Anyone have an idea?
You would bend the float arm down slightly. I also adjusted mine to have a 2-3 gal "reserve" when the gauge reads empty. 2-3 gallons isn't much especially if the vehicle is sitting on an incline.
seems to be grounded and when I test the unit she sends the message as the gauge will climb quickly to the Full. When I was on E and went to fill it I put in about 7.5 to bring it full -ie to the 3/4 mark on the gauge. Its a 16 gal tank as I said. I will let it drop below the E mark and see how many gals she takes next. Its just all so weird that it reads like that--but maybe the hang up is its a Mav gauge and the unit is matched to a Stang Gauge. ???
when you put it in the tank did you line it up so it would actally float up when it is full? kinda like a float in the back of a commode type thing if you know what i mean sometimes they shift when you tighten the lock ring if you are not careful just wondering I have had that happen to me before
Both gauges are made for the same ohms. If I had to guess...I guess it's the quality of the NEW sending unit
another possibility is the tank may be isolated from the car. If the sender is a single wire unit, the tank provides the ground path. Those tanks are usually bolted in the car and provide a good path to ground. Strapped tanks usually have 2 wire senders that provide the ground.
