Depends on your budget. I believe a full flowing pump like an Aeromotive with a full regulated return system is best. But they aren't cheap.
What type of budget are you trying to stay within?
Also, what size injectors do you plan on using?
What do you use your truck for?
the cpr system uses the areomotive a1000 marine pump
Right. There are other kits using the same system pump.
Out of the three options above, Bob's is where I would go for a 7.3.
Whats their prices?
