Hi folks,

97 F350 dually PSD with 190k, stock except for the air filter. Dual tanks are crudded up - when either gets below 1/4, it runs rough, even stalled out on me once. I have been keeping them full-ish and switching over at 1/4 tank. I don't drive it much (dump and home depot) so it sits a lot. Thing is, I'm hauling a 5th wheel 2000 miles in the spring, so I would like to go completely through the fuel system -- drop the tanks, replace senders, gaskets, orings, etc, blow out the switch and lines all the way to the fuel pump. Be a good time to do an electric conversion, but I can't afford that right now.

I can turn a wrench but have no exp on diesel fuel systems, so any guidance is welcome. Be nice to see a YT of somebody actually doing it. I have the service manual on CD-ROM but didn't see much detail.

I full timed in a 5th wheel back in 2013-2014, and didn't have any trouble, but I think it's gotten worse with time. Also I was getting high EGT (~1200) even on small hills, but around 800 on flat ground. MPG was miserable, maybe 6-8. Any suggestions on that?

Thanks,
Darryl

Sounds like the pickups in the tanks are bad. Common problem with these trucks as they age. They fall apart, and then start sucking air around 1/4tank mark.

If you still have stock down pipe (flattened) you’ll have higher EGT. Is your boost decent? Does it seem sluggish (for a 7.3)? I’d look for exhaust leaks (up pipes, exhaust manifolds, turbo mount). I’d also check turbo flow to intake for any leaks. You need a good flowing exhaust to get the benefit of improved air intake. If you put together your own e fuel you can do it for about $300 give or take. I just hate all you have to go through to replace the stock fuel pump. I’d also run a tank of hotshots secret in fuel and stiction eliminator in oil. Normally helps, I know it can’t hurt.
