Default Fuel Pump

Ha never thought i'd have to look into this, this hobby gets addicting.

Well, need to upgrade my fuel pump and injectors. Found a set of 243s cheap off a ls6, having them ported and polished as we speak. Talk with my tuner and he said id see a bigger gain if i get new pump and injectors since on my current set up are maxxed out. int he summer my injectors are like 95-97 duty cycle and probably 100 in the winter, fuel pump been max as well.

I also have a NNBS intake i got for free, nothing on it tho just bare manifold. Would also like to do the swap while i have the heads off.

i've done research of pumps and found a few walbro pumps come ready to drop in (premade bucket and everything) but all the write ups i see are based just the fuel pump using the stock bucket. Was wondering if there is a drop in that would work with my set up and also what injectors you guys rec to run.

It is super easy to add a bigger pump to your stock bucket, I would swap in a Aeromotive 340 and call it a day. You
could run stock TBSS injectors with your setup as well. I made over 400 to the tire with a TBSS intake/injectors/cam on an LQ9 with a 340 pump
