hello guys ,I need your help with my fuel system on my 07 nnbs .
I have searched and read many threads with many different opinonson what will work.
my setup consists of a forged 370,80#injectors,pt88mm,15#of boost 4l80e .its is almost complete and ready for the streets,but iam not feeling the fuel setup its a stock bucket with a aeromotive 340 pump.
how much hp will it support after all the tuning has been done to the fuel pump module?I would hate to leave to much hp on the table due to the fuel system.i would like to keep the stock tank .
will my pump support 650hp?
do I gut the bucket and add a pump and external regulator and returnline?
do I sump the tank with one of those sump fittings the diesel guys use?
thanks guys and sorry for all the questions

 

anyone ???

 

In to learn. Sorry, I'm no help buddy, but I'd like to hear what the pros say...

 

I setup the boosted Nnbs trucks with a sinister diesel sump and a Magnafuel 4303 fuel pump and Magnafuel boost reference regulator and just get rid of that fuel pump module. Use the stock feed line as a return. Pump is a little loud depending where you mount it but nothing crazy. Right now trying to get a billet fuel hat made so I can setup the 4303 as an in tank setup.

 

thanks for the response guys I will look into your suggestion three6gmc.

 

There are people on here using the walbro 450 on the stock bucket making good power. I put one in mine to not have to worry about fuel issues for a while.

 

I like this idea .. Can you send me some pictures of your setup ?

 

Yeah no prob I'll try and snap some this weekend when I'm on days off. Have done this setup on a few trucks now with no problems.

 

I'm using the Walbro 450 on my nnbs with a Magnafuel regulator, I'm interested in the Magnafuel pump 4303. Are you just using the 4303 Magnafuel pump or do you have a in tank pump as well?

 

id love to see this
