Walbro Pump instead of BAP???? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

RobSS · 04-29-2011, 08:05 PM

Just trying to get some knowledge on this fuel pump. Why would I buy a BAP for $250 when I can get a Walbro pump for 125? Just wanting peoples input here. Thanks

Really? didn't know they were that cheap. I'm positive that the install of a BAP is much simpler than a new pump though.

I am in no way an expert here but from what I have gathered so far, you cant just drop in an aftermarket pump. Most aftermarket pumps will not be compatible due to the way the Camaro fuel control system electronically modulates flow/pressure. Aftermarket pumps will not work on a vehicle system that uses pulse width modulation to control the pump output. It's not just a drop-in affair or people would not be spending a grand or more on adding fuel pump upgrades.

You can add an aftermarket pump and return line style fuel system and re-engineer the whole fuel supply including dealing with the electronic control module. Aftermarket pump install is FAR from easy and cheap. No HP limit - just keep upping the system until you have more than enough fuel.

You can keep the factory returnless style system and buy compatible pumps (from other GM applications) and install those upgrades. GM pump style upgrades are sort of easy, somewhat expensive and they are very reliable. More HP potential than a boost a pump.

Boost a pump is easier and cheaper but you can only go just a bit more HP before the BAP runs out of potential. Some would question reliability.

I am sure you will get a better answer from someone who knows this stuff more than I do but this is pretty close.
