stick with OEM regulator, or switch to AFPR ?

Alright well I plan to have the motor back in next month, I'm just trying to get the fuel system out of the way while the engine bay's still empty. Still have to fix my fuel filter problem and later do the fuel pump rewire.

I'm planning on using a fuel lab filter with braided hoses and AN fittings since I have them. I was wondering If it would be a problem to use the stock sized regulator if I have a fuel lab filter, plus I'd have the rewire done. I'm deffinatley going to switch to an AFPR for the info & control but it'd just help me get everything done faster if it was okay to use the stock regulator and monitor fuel with just the wideband I already have.

but I've heard the stock regulator is already a restriction, and especially on the AWDs because of a different gas return path from the gas tank being in different spots.

If you plan on running a walbro 255, you will need the AFPR due to factory fpr getting overrun by the higher displacement fuel pump!

I'm not looking to buy any new pumps unless the one I have stops working. Just going to do the rewire and new filter install.

Do you think the factory pump rewired with a new fuel lab filter would over run the factory regulator?

No the factory one will be fine.

there ARE people who run stock reg even with a walbro 255. it can and does work, however its only a matter of time til you over run it and start running rich at idle. this is what ive read anyway, quite a few times. i believe the member "clipto" isnt using one.
after reading many threads on the topic ive opted to install one. just my .02

I think it works at lower levels of boost but when you need it, it'll be over run instantly.
