Which model number is the correct intank pump? I see a lot of choices but not quite sure which one fits my 2002 5.4. Will this pump be ok with a Vortech? I'm about to add one. Do I also use the T Rex or just leave it out if I get the Walbro? Or is the stock one and the T Rex good enough to supply the fuel?

 

I wouldn't add a used fuel pump to your already used fuel pump. I think this one is a plug and play version, but may require slight modification to the in tank bracket. The swap is about a 4 hour job on jack stands, but not too difficult.

Get the kit ONELOWF posted a link to. No need for any other pump as the 255 will handle the blower just fine.

not sure if i explained it right. i'm going to replace the old pump with the new walbro, just want the right one if there is a plug and play version. would the T Rex that comes with the blower be a benefit to add in front of the new walbro in tank pump? or just use the one intank walbro?

 

Oh, Ok. No need for more than the 255 alone.

 

Would the stock pump plus the T Rex be better? Which will provide the most fuel?

 

Has anyonne tried the Walbro HP? Should I get the standard one or spend the extra $10 for the high pressure just in case I need it later on.

 

a 255 is good for about 450-500fwhp dependin on your BSFC

 

"BSFC"? I'm new to this so you lost me.... I don't think I'll make over 500 so the 255 should be good......unless this really gets out of hand.....

 

Brake specific fuel consumption= the amount of fuel used to make power. it is a number used to caculate fuel requirements of a particular horsepower target. every engine is different. there are books out there on amazon that can explain more
