Hey ya'll, just trying to get some information on the stock fuel system. I am actually looking at putting a stock SD fuel system with dual Bosch fuel pumps on my 97 OBS 7.3. I can get my hands on a stock SD fuel system for next to nothing and can get brand new Bosch fuel pumps for $67 each so it is ALOT cheaper then buying or even building my own e fuel set up. While I know (at least from my research) that dual Bosch fuel pumps can fuel 300cc/200% injectors without a problem? (I am running 250cc/100% hybrids) Is there any "bottle necks" in the factory system? What would be the limit to what the stock system can handle? Are the lines/system sufficient/large enough to flow enough fuel that dual pumps would put out? It looks like 400ish rwhp is the limit to the stock system with just one pump? I know I would need a sump or draw straw (I am running just one fuel tank and the selector valve was removed). If your running dual Bosch fuel pumps or even a upgraded fuel pump with the stock fuel system. Post up your setup (injector size, fuel pump and other mods you have) and what type of PSI your seeing at WOT. Any other input is greatly appreciated!

I would install an adjustable regulator and 4 line feed if I was you.

444fab has good kits for obs trucks

Dual Bosch pumps are great.
