Hey guys I'm finishing up my swap on my 5.3 into my Jeep grand Cherokee. On the fuel pump assembly my feed fitting is 5/16 running to 3/8. Anyone see this being a problem for a stock motor. I have a aeromotive stealth 340 pump. Any help is appreciated!

 

No problem whatsoever.

 

Any idea at what horse power ill need to upgrade to a bigger feed? I have a vortec v2 ready for install this winter. I'm aiming for the 500-600hp mark.

 

3/8 feed line will support 1000 hp with the right pump(s)
