i am working on building a 5.4L and adding L/H s/c and the likes. what were the OEM fuel pumps rated LPH on these newer lightnings?

also, will one of these 255lph pumps on ebay suffice the demand of these supercharged engines?

 

If I am not mistaken the stock L fuel pumps are 155 lph. Most modded trucks are running 255 lph. I am running the 255's and no problems.

 

HI!... Or you could go this route like me! LOL!

the oem pumps are 2 155lph? so either way i would have to do over kill like neal or run 2 255lph's?

 

do the regular F-150's have twin fuel pumps??

 

HI!... No.

 

so to do this effectively / correctly i need to have 1 255lph pump? or 2 of them?

meaning the oem setups was 310lph on these lightnings?

Neal, what was your retail price on that monster?

 

yes, the lightning is stock with twin 155's and most all modded guys go with twin 255's. Mine is built and the twin 255's hold 60 psi as long as my foot is on the floor. KB says you can use a boost-a-pump up to a certain point. lots of fuel and plenty of pressure with the twin 255's....

 

HI!... It was around $425(CAN). But I got that price through a package deal. I ordered the fuel pump, before filter, after filter, regulator, and fuel rails. All from AEROMOTIVE. I believe I got everything priced out to about $1300(CAN). The pump flow exceeds 800lbs. per hour
