Looks to me like the fuel pressure regulator (fpr) is plumbed in wrong in that diagram. Not sure about LS's (are they return-less systems as shown in the diagram), but the feed from the swirl pot usually goes directly to the fuel rails, either plumbed in series or parallel and then to the fpr and finally returning back to back to the swirl pot.
Alex, re-read your last post. ?????
It is indeed a return-less system then. I did not know that.There are about 6 LS powered SLCs plumbed exactly as in my diagram and all is good (with single input to fuel rails). Because the stock LS does not provide a return from fuel rails, it is accomplished thru the FPR.
I put the Pyle camera/ monitor in and it is pretty good. I wired it on all the time and it sorta doubels as a rear view mirror. but back up camera were designed to look 20 to 40 ft behingd you. the image gets blurry 50 to 100ft, but better than nada. I got the 380x60 TV lines which ain't great resolutoin. Pyle now has 420 lines but I'd bet there are XVGA cameras out there. OH, in the pic is my superbowl prediction. Green Bay +7, but you can barely read it.
