Hello, I noticed that my fuel pump housing has been leaking a lot, as it has a big crack under it, and the problem has effects on the fuel pressure on my 8v k-jet. I can't find any decent boxes in my area and online, its a bit too expensive for me atm, so i decided to ditch the whole assembly and install a walbro 255 pump. My question is, is it possible to run the stock in tank pump along with the walbro in-line? What other things do i have to take care of? Is it better to just install the new pump in-tank?
