Erradic fuel level reading with Ricks tank

[DRJDVM's '69]

I just put my Ricks tank in about 4 months ago and my fuel level guage is all over the place.... it varies about 1/4-1/3 of a tank on a minute to minute basis. In other words it may say 1/2 full one minute and then the next it says 1/4, then a minute or two later it says 1/3 tank, then back to 1/2 a coupe of minutes after that. I'm using an Autometer guage and I've tried 3 diff ground locations all with the same issue. The tank has an in tank Aeromtove pump with a return.

I called Ricks and spoke with Hector..... he said this is pretty normal and that since its a direct reading from sender to guage (i.e no computer in between etc) it reads stuff really fast, so as the fuel moves around, the guage reacts right away. He said Rick had mentioned something about a resistor or diode that may help, and he would get back to me. He said the sender is fine.

Its really annoying when I'm getting below 1/3 of a tank....one minute I'm freaked I need to find a gas station NOW since its on E and then its back to 1/3 of a tank a couple of minutes later. One of these time I'm gonna ignore it and its really going to be empty.....

So are you guys with Ricks tanks getting the same issue ???
