Fuel system greamilins....
Fuel system greamilins.... I just did a bunch of modifications to the fuel system. It consists of:
deleted EVAP,
used EVAP hard line as my new return line, connected to the stock return past the "tee" in the rear of the car.
removed intank regulator
CAS BRFPR
Speed Inc Rails
FMU, temporarily before I get a tune.
255 lph hp intank walbro
255 lph hp inline msd pump, I turn it on and off at will, switch in teh cabin.
Since the speed inc rails and the return line were done, when I try to start teh car from cold, the single intank walbro seems to not be able to pump up the pressure enough when it does its run for a few seconds when turning the key to "on", If I cycle the key to on 2 times then its ok, otherwise the car will turn over for a few seconds before building enough pressure to start, this seems very strange to me, I have hte base FP set to about 60 lbs right now.
On one day the single walbro seemed to not like running alone when I gave it gas the pressure woudl drop, so I had to run the inline as well and then pressure would rise 1:1 as it should withthe CAS unit. Base pressure was set at 52 this day.
The next day the single walbro seemed to be doing just fine, and if I turn on the inline pump, pressure woudl spike up to 80 psi... I never touched the regulator but the base rpessure rose to 60 this day...
Its just all over the place, the starting thing is what is really cooking my noodles though. Any thoughts?
TIA
