2001 Powerstroke Fuel System Question

Up to this point I have always had a 24v Cummins engine and I am fluent in Cummins mods. However, I know very little about the powerstroke. I searched and could not find this answer so here goes...

When I started playing with my Cummins I upgraded my lift pump to a FASS HPFP pusher pump and I also installed a big line kit from pump to filter and I also installed a Vulcan draw straw. My question is this: Is this something I need to do to my 7.3l and if so where do I get the parts? I checked the web and can find neither part for the 7.3l other than the FASS pump.

Hope someone can help me. Also, on the Cummins it was generally accepted that you did not exceed about 150hp over stock without major tranny upgrades. Is there a similiar rule of thumb for the 7.3l?

Thanks for the help guys.

Fuel system is fine until you start looking at injectors... Hybrids is where you would generally need a fuel system...

Tranny is the weak point on these trucks... Stock HP and TQ they can barely hold up to...

The ONLY thing you need to worry about a fuel system is your hpop when you do stage II sticks or higher (keep in mind; upgrading your hpop will also give you better mileage, a quieter motor, more hp/tq, and an easier idle.. it's not a transparent mod like getting a better lift pump for a 24v).
Of course, the regulated return for the fuel system and oiling system is also good for the same reasons (idle quality, more fuel/oil, quieter truck...)

ALL auto trannies suck on diesels from the factory. Although I would say the Fords are a BIT tougher than the dodges, all in all they blow goats. Start saving up for a TC and VB.
