wait, since i cant open the video, what kind of car is this we're talkin about again?
i doubt its the regulator, as previously suggested, even if you take the screw off the regulartor, pressure will not go down to 20psi. martin |

you need a fuel filter thats meant for fuel injection on the car. efi runs at 50psi and a carb setup runs at 5psi... try a fuel filter for say an fc, or something fuel injected Wow, that's a pretty ignorant mistake for me to make! I bet that's exactly what the issue is. Fikse this is my Cosmo -> FB swap. |
lol i agree with j9fd3s then..... filter is too constricing, i bet your walbro is whining like a cat with its tail under your front tires
|
yep id definitely say its that filter then.

i helped my friend install a TII motor into an 82, and we used a gsl-se fuel filter in the car. fuel pressure was at 40 (before other issues came along, rusty fuel tank). so you might want to take a look inside your tank too, make sure that the thing is not rusting and clogging your pickup filter, and eventually ******* up your injectors and eventually your motor.(tahts what happenned to his car).

At least one of Aeromotive's regualators comes with two springs. One for low, carb pressures and another for high, FI pressures. If your's came with two springs and it has the wrong one in you may have the carb spring bottomed out and it simply just won't make any more pressure. Also, is it possible you just bought the wrong regulator? What is the model number?

Thanks for the advice guys. I installed a fuel filter from a TII and was able to adjust the fuel pressure just fine.
It idles a lot better with lower fuel pressure...I actually have to put my foot on the throttle to keep it idling with 50psi of pressure. Does that sound right at all? It still doesn't like to rev but it needs some tuning I'm positive haha. I'll work on getting it rolling now and then getting it to a dyno. |

Fuel injectors work the same no matter the fuel pressure, so if your pressure is lower, and the injector opens for a millisecond, it's just squirting in less fuel than if the pressure was doubled
Sounds to me like you should increase the pressure and back off the injectors. You base map for idling is too rich at the proper pressure. So, if the pressure drops, and you haven't touched the fuel map, it will be closer to the proper ratio, so it idles better. |
