Default Fuel pump swap help plizz

My friend just wrecked his 240sx



so i stoled his fuel pump. the car will never run anyway and the inssurance company is taking it...
so we made few pics on it.. iam holding the camera




and now for the fuel pump
actually with the help of some ilustrated FAQ from HMT
i had no problem at all





as u can see the nissan stock pump is quite bigger than the stock honda
the final install looked like that





at the end I had a hell of luck because the hole in the tank was just perfect to put the new pump, if it was smaller then i would have got stuck..




the only problem is that now iam runing rich like hell, how ever i reduced the fuel pressure on the fuel rail from 4.5 to 2BAR iam still running rich.. why is that soo?
Does same pressure means the same if its from different pumps.
I have a homemade fuel pressure meter and its not lying...
i must do some dyno runs

uhmmmm depends how much the pump flows...if it is a bigger pump that flows more..it will push more fuel than the smaller pump at the same pressure

are u sure of that.
I dont get howcome more fuel can be pushed in the same wire at a lower pressure..
Anyone would know if that swap was good or should i seek for another fuel pomp.
My car isnt working anyway for few days, Iam about to install a Unichep Dastek to manage the all crap
anyone help? ( with the pump)
