Fuel Tank - How to Drain??
#16
Really? My '97 and e99 fit the big nozzles. AFAIK both trucks were bone stock when I got them ... both of them were also originally fleet trucks though, for big oil.

I know my stock 99.5 didn't fit them. I could hold the bigger nozzle over the hole n try n aim carefully, but they didn't fit inside it. Anyone know what size the big rig nozzles are? Think I reamed mine out to about 1 1/4"

Back to the OP. Part of the issue with the stock fuel system, is the in-tank fuel strainer which is part of the umbrella or pickup foot inside the tank. This is the plastic part which either falls off, breaks, or gets clogged if you've gotten dirty fuel. Many will re-use or replace the plastic umbrella part, but remove the screen. Instead we'll install an external fuel strainer between the tank and the fuel pump, where it can be inspected and changed, if needed. It's important to note that it's a strainer, not filter. Your filter is under the hood, the strainer is only there to protect the pump.
The umbrella part is re-used to get the new pickup line right to the bottom of the tank. We also replace all of the OEM quick disconnect fittings located before the pump with doubled up hose clamps, and new high quality diesel fuel rated fuel lines.
Let us know how everything works out for you!

This is a picture of the exterior strainer (Racor Filter) mounted between the tank and pump.

I have no idea on whether this is true or not, but others have voiced concerns that a filter before the pump may be too restrictive on flow - our pumps are better at pushing fuel than sucking it. Hence our filter is located after the pump, on top of the engine.
That's why folks have gone with a fuel strainer pre-pump, less restrictive. By no means is the pricey Racor PS120 the only option, but these strainers are pretty much the go to option for big diesel applications, like big trucks, marine engines, etc. Just another point of view...

Riffraff Diesel Inline Fuel Filter Canister
And there are replacement filters available.
Is this what you're talking about when you say the small one?

Inside the suction end of the fuel pump is a 56 mesh screen which keeps damaging particulates from entering the pumps smaller crevices inside. The real purpose of the "in tank" or pre-pump strainer is to simply avoid plugging up that screen inside the pump. I had initially estimated the mesh at 64, but just zoomed in on the picture, recounted the openings, and it is indeed a 56 mesh count. Any mesh count higher than 56 will protect the pump's internal screen, but if you get too tight you will create pump starvation issues at high flow demand. The 120 mesh in the Racor PS120 strainer works beautifully!
Clay's inline units look nice and are compact, but for about the same amount of money for the PS120, I would personally rather have the larger filtration surface in the PS120 for less strain on the pump, and at the same time get a clear bowl for being able to see what is or is not going on with both contaminants and air entrainment. That's just my own personal preference, though.
In terms of the small clear bodied unit referenced by you, I ran one of those on my Excursion for about 5 or 6 years, and it really does not take very much crud to really plug off the fuel flow. Yes, it is less costly and very compact, and it can be cleaned. The small unit just doesn't hold very much, and once you take it apart to clean it, it can be difficult to get each end of the clear tube to completely seal to prevent air entrainment. I'm much much happier with the larger PS120 in place now. Again, personal preference.
The reason for not relying solely on the pump's internal screen (having another one ahead of the pump) is because the pump itself cannot be disassembled and cleaned without destroying it completely.
Here is a link to a thread I posted some time back when I tore down a stock pump to see how it was built... pictures included.

Sorry I was refering to the white strainer that was in the picture, as I feel the Racore is just too much, not looking to redesign the entire system, and would like to put a strainer back in line as I too out the intank screens (replaced pickup foot and put the new one with screen in tank) but would like to have something to replace the in tank screens. I would like the more compact ones for ease of install and I don't mind if I might need to empty it more often anyways.
