same. However i had bought SARD fuel pump rather then Walbro 255
bcos due to Walbro size is larger and my car cannot fit in.
However Sard 265 is smaller yet able bigger flowrate.

I also looking for Rising Rate fuel regulator to replace my current new Sard F.regulator

fuel rail is where ur injector sits... fuel regulator regulates the amount of fuel on ur fuel return line.... yes, most car fueling system has fuel return line so the fuel pressure wont get too high during idle....

adjustable fuel regulator enables u to regulate the fuel pressure in ur fuel rail by limiting the amount of fuel returning to the return line...

yes it does, by using bigger fuel pump motor, it keeps your fuel rail with more pressure, it improves pickup and top speed. it is a very significant noticable engine respond improvement. adding F/R will further helps for cars that has enlarged bore+stroke and also with highcams.

for a stock car, adding bigger fuel pump motor will give effect wherehence the F/R will give minimal effect (experience may vary, but I tried adding F/R to 3 stock cars n it made no diff)
