rb20det fuel pressure at idle
rb20det fuel pressure at idle
Just installed a AFPR and fuel pressure gauge. When I get the fuel pressure adjusted below 55lbs the gauge needle starts bouncing. Does not make any difference with or without vacuum. I have the gauge installed between the filter and fuel rail. The AFPR is installed on the return line.
Re: rb20det fuel pressure at idle (foulplay)
Is the needle supposed to bounce? If not, does anyone know what the problem could be?
thanksDanny

Re: rb20det fuel pressure at idle (foulplay)
my rb26 has a nismo fpr and a b&m fuel psi gaug between the filter and fuel rail and i set my fuel preasure on mine at 44psi and when running it bounces a little bit but thats uasually normal since its a mechanical gauge so i would start out by setting your fuel psi at 44psi and go from there.

got the fuel fressure set but now above 4000 rpm motor starts missing
Re: rb20det fuel pressure at idle
weird, i had the same problem with my rb20det and the only way i can get it running nicely is to lean it ryt out. im running a dsr430 and monza fpr and to get rid of the miss the fuel pressure must be around 37psi.it runs good but i am unsure if its safe
