Hey everyone, I recently purchased a 93 ford f250 7.3l idi factory turbo with 188k and ZF5. I’ve been gradually improving it and adding things like a coolant filter and whatnot. It used to white smoke but that was handled after I found it was a stuck open thermostat.
It runs amazing using the front tank, minus the fuel gauge jumping around a bit once I get to about 60% of a tank remaining. Still no issues when it does that though and when I’m not accelerating it settles at the true fuel mark.
When I flip on the rear tank, an aftermarket larger tank (maybe 33 or 38 gallon) it runs fine for 30-60 seconds then starts shaking, stuttering, losing power, and feeling as though it’ll stall. It runs like crap.
How should I approach this? I don’t even know where to get a new fuel pump and sending unit assembly for the larger tanks because doesn’t it need to reach the bottom?
I’m unsure of the condition of the diesel in that tank, I know it’s maybe six weeks old. But it really feels like a clog or something not getting fuel.
I have a cherry picker and could pull the bed, but I would just like to know how you’d approach this. And also if a new fuel pump and sending unit is needed where would I buy it for this larger tank?
Thanks.
