Rough running at low speeds after tank fill up of diesel

[johneich]

Lately, twice, after filling the tank (I only run on the front, rear does not work) my engine runs rough nearly stalling, If I keep the revs up she keeps running and after a little while this goes away.

Is this a sign of impending doom? Any ideas on what I should look at?

This my 1983

when was the last time you did fuel filters

First time it happened I cleaned the Carrier screen and changed the filter, filled filter with ATF, problem was gone by then so I thought that fixed it but now its back. First time was about a month ago, I have not been driving much lately.

Its just happening after a fill up, I do fill up until it clicks off twice

Sounds like you are sucking air somewhere. How low do you run your tank before filling?

As of right now yes, but I am asking in case this is a sign of something I can act on now to avoid a future problem.

I fill up every two weeks or so from known local stations (A small local chain), I am not ruling out air intrusion but since its an intermittent problem I am thinking its not air which would be all the time?

You didn't really answer my question. Lol
I'm thinking that if you are running it below 1/4 tank before filling you may be sucking air. Common problem and that's what your symptoms are pointing me to: air in the system.

Do you ever have any weird noises when you take the filler cap off? Pops, bangs, air escaping, etc.

Sorry, I did get it wrong, I fill up at 1/2 a tank as I do run out at 1/4 tank (Showerhead problem), its never been under 1/2 a tank for a long time. I do not hear any weird noises when I remove the filler cap.
