fuel pump size

[mustangcobra93]

I plan on adding a Zex kit to my car in the next couple months. I wanted to upgrade the fuel pump, but wasn't sure which one I should go with. I figured if I was doing it, might as well go ahead and put a 255 lph back there. Is that ok or will it cause problems. I have 24 lb injectors.

you can put what ever size pump on you want but untill you get a fpr it isnt gonna help you at all(the stock is non-adjustable and will only allow so much fuel). if u use the 255 get a nice fpr and you will be set to spray.ok?????

Thanks. Yeah, I forgot to mention I have a Kirban adj fuel pressure regulator too.

You cant overpump a injected 5.0. Go with the 255hi pressure and you'll be all set for future mods as well.
