I was just wondering how many people have did this upgrade? Any pos or neg things about it? Is it a better buy than the entire fuel pump upgrade?
 
i have not done this but am go to in the next couple weeks. i would go with the internals kit. there is a how to posted and that's what made me decide because i didn't feel like messing with it but it doesn't look to hard.
 
I'm sure it won't make our mpg to go down that much. How did yall like the difference with this kit
 
Are you serious? What other mods do you have? I don't see how a hi flo pump could cause your mpg to go down. :confused:

Me, too. If you don't ask for the fuel, how is the delivery increased?

just did it last night,simple install.
How so? I would think the fuel pump is a bear to work on. What does the mod consist of? Sorry if there's a "how-to" on this.

There is, it's in the how-to section.. Shouldnt tkae much more than an hour or two from the start.
Basically you just take off a bolt and many a few little hex screws and switch out a piston. Pretty easy.

Yeow! Looks pretty involved. Is there not a fuel pump in the gas tank as well?

Yes, but we have cam driven fuel pumps in our cars, most other cars do not.
the cdfp is what bumps the fuel pressure to the super high fuel pressure than disi engines need.
