Walbro 392

Is anyone running one and can I just splice it in after the stock pump to keep fuel pressure up. I think the stock one is weak ot wont smoke nearly as much as it used to and I'd like to keep the stock pump and just run a helper after it.

Nobody?

I'm assuming i can take a 3/8 quick connect to 3/8 barb adapter and run rubber line the whole way and just splice the pump in there. Do I need to use a regulator with the cp3?

You will need to regulate it. That is a 70gph, 85psi pump. I use a bunch of them on 7.3 and 6.0 Powerstrokes.
Good pump, pretty cheap, plenty of fuel for 600 hp.

Awesome. Can I run a return less regulator or does it need a bypass?

I recommend a bypass regulator. Takes a lot of load off the pump.

I recommend diagnosing your truck with tools and not just by how much it smokes. If you want smoke wrap the air filter in a trash bag, or do a turbo delete. Then don’t go on the street and smoke out Honda’s because “it’s cool”.

Its gonna need a lift pump at some point. Currently building the trans but if the lift pump is not the problem then its injectors or pump which will also need replaced eventually.
