Definitely take the filter apart and check the element for any debris.

as for the injectors, injectors don't like to be stored with e85 for a long time.
I've had a few guys up here in mn who have and their fic id injectors seize up due to not pickling or running the injectors in reg pump gas before storing their cars over the winter.

did your car sit for a while (more than 1 month) without being started?


if you have inline filter, chances are it's not clogged.

Most it has sat for is maybe three weeks while I've been at work.

Just doesn't make sense cause I beat on it and it runs fine then that last time at the track it f'd me.

If it does it again imma toss the dual hanger just to 100/ eliminate that as a possibility.

How are you all running your single pumps stock hanger with a fitting welded to the top?

well if the injector isn't stuck, maybe the driver is just bad.
it reminds of of the rc550-750cc injectors, after a while injectors go bad and start cutting out on customers cars when they are in high boost and injectors are above 90%....


have you tried turning down the boost and going WOT to see if injector/fuel is cutting off?




with my walbro 400, i ran a crush washer + 1.25 metric to -6 straight + -6an 90degree fitting to -6an hose. Nothing complicated.

You could also have a problem with your regulator.. it could have debris in it or the diaphragm could be torn, stuck, or damaged in some way.

haha yea never thought of that, doh.

definitely datalog so we can have hard data when it starts acting up. however if you don't have a way to datalog fuel pressure it might be hard to tell what's going on

I never heard of a s300 that doesn't data log, so yea I can... I have it turned on to auto record my runs but I will run my laptop next track so I can have the complete iteration from pit to pit on the track.

But like boost said I don't have a fuel preasure linked to it.
