I was told I could use my stock fuel pump on my 91 hf when swapping in a dohc zc but I think how in the hell could it do the job for the motor... anyone have any input?

 

Because the fuel pumps are the same in all models.

 

It will work fine. My stock dx pump has been supporting my b16a without any problems.

 

Oh ok thanks for clearing that up for me.. I thought like a lot of people may think that the Si came equipped with so much better stuff since I went from an si in 2000 to an hf now. Thanks again guys for clearing that up for me

 

i will be using my stock HF pump on my turbo project, so it should definately be able to support your ZC.

 

that makes me feel a lot better, You know on eg's everyone buys a bigger fuel pump at least everyone I know so it made me wonder thats all... glad to see my stock one is good. thanks

 

A lot of the time they buy a bigger pump and it is overkill. I bet more then a number of them strapped on a 75 shot and then added a 255lph pump instead of something more reasonable like a 190lph. Even though the argument is that the 255 gives you more room to grow I don't like having to regulate that much more fuel pressure in day to day life if I am not using it.
