SPF Fuel Safe 18 gallon racing cell

Can anyone help me get the proper fuel level reading on my fuel guage?

I have tried using the "Full" and "Empty" adjustment screws without any luck. My first time out, the fuel guage was adjusted to a "full" reading, but the car ran out of gas at the halfway point on the guage. The last attempt was done with the tank at the point of being empty with the appropriate "empty" reading on the guage. Upon filling the tank up at the gas station, the guage reading was about 1/8 below the half way point.

It seems that I am unable to utilize the whole fuel guage to get a proper reading.

Any recommended methods on adjusting the guage or similar problems experienced before I contact fuel safe?

Gene,
Right now the fuel gauge in my SPF/Fuel Safe cell is fairly accurate. My gauge readout is not linear but it isn’t too bad. It took a few tanks of fuel to get the adjustment to this point. From your description, it sounds like you have the full adjustment set too high. I would fill the cell and make a minor adjustment on the full side first. Adjust so the needle just starts to come off of full and then adjust it to full. The gauge response is slow. Then, knowing your fuel mileage, you should be able to make minor adjustments on the empty side as you know when the tank is approximately ¼ - 1/8 full. You may need to keep balancing the 2 adjustments for a few tanks.
If I had to do it over again, I would have purchased a new access panel gasket from Fuel Safe when the cell was new and manually moved the float around to make the adjustments. I won’t do that now because I will not energize the car’s electrical system while I am staring into an open container of fuel and vapors.

Good luck

Yup, like robert, I had to adjust at empty and then again at full a couple of times. After several rounds it is reading fairly accurate but not perfect.

Robert & Curt,

Thanks for the suggestions. I will try getting the guage to read accurately with continued attempts at setting the adjustment screws. I think my friend also requested some instructions from Fuel Safe today. At just under 10 MPG on the freeway (I can only imagine what city driving should look like),.......the needle in the guage will certainly be active!
