Warning this is my first post here and I apologize for my spelling /grammer they tried in school but you cant fix stupid... anyway I have a 1991 F350 with the 7.3l idi. I just recently purchased the truck and am slowly gojng threw it doing all the maintenace and what not. but so far one of the biggest problems ive had with the truck is with the fuel tanks.
Since i got it the truck will start running rough and stall if i get past half a tank on either of my tanks and acts as if its eiter out of diesel or is pulling air. has done it a few times when i was close to half and went down a hill and I watched the guage drop from fuel swishing around in there . As soon as it gets some diesel in there fires right up runs great no issues , that goes for both tanks. I havent dropped the tanks yet just becasue i dont have time and need to drive the truck for work.
before I do drop the tanks i was wondering if anyone had run into a similar issue? by the way i know its not the guage becasue if you fill the tank to full it will only ever take 10 gallons on the large rear tank which i believe is a 22 and only 7ish on the front tank which isa 16. not 100% Sure what size tanks these things came with but defenatly more than 10 gallons...
The only two situations i can think of that would casue soemthing like this is either A the pickup in the tank is broken off or damaged somehow which I think is kind of unlikely for both tanks to do that but not impossible, or B there is a hole/rust holes of some kind on the pickup tube that are allowing air to be sucked into the system once the fuel level reaches a certain point .. any help with this would be much appreciated thanks.
