Title: External fuel pump & regulator
Post by: Buck on Thursday, 20 May 2021, 10:45 AM
Hi everyone I'm looking for some help. I am building a chop with a k2 gsx1400 engine & I'm looking to use an external fuel pump & regulator as the original fuel pump wont fit my custom tank. Can anyone please help & point me in the right direction as to what pump & regulator I need.

All info much appreciated.

Buck 🤘

P.S I also have a k7 final edition as I just love the 14s 🤘

Hi Buck, I know nothing about external fuel pumps, but this same question came up recently & there was only 1 response, that was from T24, his answer is below.  Hope it's of some use to you.




I have seen external pump and regulator in turbo GSX here in turboland. The pump was Bosch "044" type, but the type of regulator I can't
remember.
But if you are going to run stock engine without turbo, you need only 1:1,  3 bar regulator, and you don't need so big pump either.

Almost every external fuel pump from any fuel injected car will fit (Bosch, Mitsubishi). You don't need any high perf pumps.
The regu you'll need is direct 3 bar regulator with no vacuum corrections.

The 99 / 2000 hayabusa.. has a external fuel pump for the injection. ..just to add to the search.

I opted to fit a stock 14 fuel pump in my project to hide it.

The fpr is 3bar like mentioned earlier.
