what would be a better option??

1.) stock fuel pump with an in-line fuel pump.

or

2.) replace stock fuel pump with an aftermarket performance pump (walbro-sp?)...

what pressure is the stock fuel pump and what pressure is the after market fuel pump??

thanks...

 

how old is your stocker? if its still pretty fresh an in line pump would do you fine.... what injectors are in your 6.0? if they're not too huge you wont need anything bigger than a 255lph. Even with a shot.

 

seems like a lot of guys on here run the 255 lph walboro in-tank. ask dlh2006 (i think that is his name) he has a 6.0 with a cam and bolt ons. he is running the walboro.

 

I have done the Walbro intank swap, that's the way I would go. I just think that even with an inline pump, you're still limited to a point of what your stock pump can provide.

 

walbro 255 LPH, easy *** hell to install and BTW both pumps should supply 60PSI AT WOT, thats what the fuel pressure regulator does.

 

I dont understand how an inline works tho. Does it just tell the stock pump to pump more? I mean I guess what im thinking is if you take somethign that sucks say 50 PSI and you add something "INLINE" how is that gonna pull more fuel out of that stock unit only allowed to push 50 PSI?

AM i just a complete idiot thinking this? Feel free to hack away.

 

The fuel pressure drops the further away from the pump, so when you add an inline, your just helping the stock pump from dropping pressure.

 

they key here to keeping the pressure is providing the FLOW. The fuel pressure regulator controls the fuel pressure, as long as you can provide enough flow to the regulator your pressure will stay up, but if you use more fuel that the pump(s) can provide then the pressure drops. Does that help with understanding this?

 

you dont happen to have any pics of the install?? Ive heard you got to modify something on the tank??

 

I am lookin to do the same thing on my truck does anyone have a part number and a link to buy the walbro pump?
