Ant 7.3 nuts on here?

[User170512]

Curious how hard to drop the rear tank and clean the filters and see if that fixes the problem before dropping the front.

Also could both clog at the same time and could the tank selector switch have some trash in it keeping the correct amount of fuel from getting to the motor? Truck runs and idels fine until itd under load

Sometimes easier to raise the bed.

What has me worried wether drop the tank or pull the bed is the truck is from up north. Its not super bad in rust but had some rust

if your dropping the tank do the hutch and harpoon mod if it works for your year truck. It will save you a headache later. Also I would check out riffraff diesel you can purchase the fuel pump pre filters for cheap.

just read the entire post looks like 1997 7.3 was before all the hutch problems.

97 obs. I keep getting told to check the sock filters in the sending unit. Can't find anything on them

I would think if there is trash in the tank its going to be stuck in the strainer this is what people refer to as the sock.

I just hate to drop the tank and there not be any socks in the tank

Its faster and easier to just set the bed back or out of the way. The sock is probably no on it but there should be at least screens in the pick up tube. Then there's screens in the pump or should be at the inlet.

There are no “socks” in the tanks on a 97. It just has a plastic piece with a screen. There would have to be a ton of trash in the tank to clog that screen. Most common problem with those is they break off and will run out of fuel at 1/4 tank, which doesn’t sound like the problem.

Depending on what you mean by it seeming like it’s not getting fuel, could be a few things.

If the truck starts dying under a load, then I would check the fuel pressure regulator on the side of the bowl. There is a screen that gets trash on it. Check the fuel tank selector valve on the frame rail.

If the truck just feels weak, check your EBP sensor and tube and see if they’re clogged with carbon. Also check the MAP sensor and hose going to it.

Ideally you would want to get a scan tool on it and check values for EBP and MAP. Also would want to check boost pressure, leaking up pipes are common and affect it building boost.

There are plenty of possibilities, but I’d start with those.
