Here is what I use to watch my lift pump pressure, top gauge on the pillar.. Some guys just screw a manual gauge right into the lift pump housing or even into top of factory fuel filter housing.. A few options out there...
May have found my issue. My fass was gurgling a little. Over the winter, I cracked the bottom of both filters a few times to check for water. Thinking they would refill and push whatever air back into the fill tube. NOPE. I let the fass run and I cracked the filter until fuel started coming out. Fass is smoother and I didn't notice any shudder on my last hard acceleration run.
I just ordered them. Should be here in a few days. The sensor mounts right on top of the FASS unit. I'm hearing it should be around 10-12 psi at idle. Where should it be under a heavy load?? Really looking to see if the factory draw straw is my culprit. After install, I will be able to see if I need a beans sump or if the factory straw will suffice.
I already have the egt probe. Had that installed with my insight. Basically the same thing I ordered. Should be an easy install. I just went out and bought some yellow Teflon tape an some wire loom. I'm all set!
Under really heavy acceleration, what is your insight showing as FPSI? I will get up to 29-30 and just as I feel the shudder it will drop to 23-24. Once I get the gauge on the fass, I will see if it is dropping pressure.
Received 1/2 my edge kit today. Just waiting on the sensor to install into the fass unit. Super easy so far! I piggy backed off my eas system, ran the wires down to the fass, and hooked my insight up to the computer and created a fass psi PID. Took all of 15 minutes.
So far so good. Edge eas gauge installed and running fluctuates between 8.5 and 10 at idle. Called fass since I thought it was supposed to be between 10-12 and they say they set them to run between 8-10 psi. Next step is to see what pressure goes to at WOT and see if I need a sump.
