Hi . im running a 1641 with twin 34 ict's and a stock pump ? ive had a few conflicting views about running a fuel pressure regulator ? Is it needed with a stock pump ????? some people say yes so as to prevent needle and seat damage and over fuelling. some people say only really needed with an aftermarket electric pump ! your views if you please
I haven't known the need for a regulator on a stock pump with twins. I would imagine they use about the same amount of fuel as a 34 pict 3.
cheers Horts thats what i though as fills a stock carb ok and wouldn't of thought 2 small 34's would be a problem but im not that up on carbs and pressures and all that !
think it might be 2.5,i did run a regulator on mine originally then took it off and found the carbs run fine(after i sorted the spluttering,see other post)did not like the look of the regulator i had,it was the chrome one,can't think where i got it,one of usual suspects i know that much. sharky
Mmm maybe I'll try mine without then. Both Roddy and Ash told me they run in excess of 7 psi when I fitted mine at Techenders??
The aftermarket electric ones run at 3-4 and I'm not running a regulator, all seems fine. Don't know about stock. They didn't have regulators originally so I guess it should be fine
