Fuel pump/injector ratings
 

Hey, new here and wondering if anyone can supply some info regarding the fuel pump and injectors I've put into my truck.

Goofy question I know, but here's the long story.
We had an 09 Denali 6.2 and installed an edelbrock e-force supercharger, factory fuel system was adequate as it was a flex fuel truck.

Life goes buy, trailers get bigger, we upgrade to a duramax and sell the Denali. Won't sell with the blower, no ones interested, too expensive; the whole works, you know how it goes.

So we remove the supercharger, sell the truck, and here I am 3 years later putting this supercharger into my 1999 Sierra with a 5.3. I purchase stock fuel injectors for an 09 Denali and the supplemental fuel system from edelbrock to run this blower in a truck like mine with return fuel, fuel system part number is 15773.

So back to my original question, can any one supply info on what my pump rating is and also my injector rating. I need to change my injector flow rating in my tune file before I can go any further on tuning my truck.

And yes, I've searched many places all over the internet.

Thanks!

The part number on the injectors would make it really easy to find the flow rate, that info is everywhere. Or just look at a stock 6.2 tune file with flex fuel injectors. They are 50-52lb/hr at 58psi. But that is only part of the info you need, the injector offsets, short pulse adder, min injector pulse and things like that all should be changed when swapping injectors. The only issue here is that P01/P59 controllers use different tables, data and axis for all this information compared to the newer E67 and E38 controllers that a denali truck runs. Try to get it as close as you can I guess.

No idea on the extra pump. That seems like a un-needed part because those injectors will flow more than enough fuel on their own. You just need a 255lph pump in the trucks fuel tank to support 400-500hp on pump gas.

The fuel injector is a BWD injector and their number is 67645. Is there like one website with all that info on it or something like that?

I bought the supplemental fuel system more for the regulator and fuel lines it came with as it looks very clean and almost like an oe look. However, I will likely still install fuel pump

HP Tuners tune repository is back up.

Oh I didn't even think to look there, completely slipped my mind, appreciate it a lot thanks!

So are you using an adapter to fit the blower on the 5.3 heads since the port are differant

Yes, it's an adapter from lsx innovations. Only thing i didn't like is the bolts it came with were an Allan head and too small to cover the bolt hole completely. I just went and found washers that fit, but hex head would of been easier to torque
