So, had fuel in the intake, rough idle and seemed like hesitation when up to cruising speed and trying to accelerate. Still drivable but just not right. Ordered a FJ504 and installed it with no issues. I'd had the heads off of this motor a few months back so I remembered how it all came apart and actually did the job right at 2 hours while on shift at the FD haha. Buttoned it all back up and it fired right up and ran like a champ. The next morning when I got off however it was slow starting. Probably took a good 2 seconds to fire then it stumbled to life. Seemed to run fine after that though. Now I have to cycle the pump 3 or 4 times before it will start normally. If I don't it takes forever like it did that first day. Am I to assume that I got a bad spider out of the box? Because obviously my pressure is bleeding off over the course of a few hours. It takes it 3-4 hours to bleed down to where its noticeable on startup. Another possibility I thought of was if I somehow knocked one of the o rings off the connections on the hard lines would that cause it? I assume there is a check valve up in the spider itself that should hold fuel in it even if I did lose the ring. I've looked and I don't see any fuel leaking externally so Im leaning towards the unit itself being bad. Also just a note, as of 3 months ago it has a brand new Delphi fuel pump and fuel filter. So with the exception of the lines the whole system is new. Just want a few opinions in case ive missed something obvious before I go to tearing into it again. Thanks!
