Amen.

Walbro 155 lph will pump almost 2x what stock injectors can flow at 80% duty cycle at 43.5 psi fp. That means at wfo, 155 pump can pump almost twice what injectors (engine) needs. One has to remember that if you use a fuel pump that's too big, you might outpump the capacity of return line...

Agree. I'm in MN so OReilly is common. I wouldn't mind the kink so much if it wasn't exactly where fuel pump suction port is! That's why I searched and found that one from OReilly with 90 deg connection fitting.

Exactly. Why I commented 155 is plenty for even a 320hp 998 with stock injectors and stock turbo. Simple math.

Yup, I've noticed that one also. That protective metal sleeve is pretty good though. But I still did same as you to make sure.

155 lph is plenty big enough.

Cat p/n 1686-802.

Have you tried a offset pry bar, like one with a bend near end so you can apply force more towards back of pistons?

Looking for 3" Viney Fab or 3" Sandale Hyperflow muffler for 998. Prefer gently used but will consider new.

I thought you were referring to the actual tank vent where that clear line is connected to?

Did you remove the vent fitting from tank to do that? How is it secured into tank?

Pump gas (91)?

I've fixed 998s that run "only" about 14-15 psi boost where I could tell head wasn't sealed completely. IMO, knowing what I know now, I'd say head studs on anything above 12-13 lbs boost. Stock torque-to-yield head bolts just don't provide enough clamp force for me. But, ARP head studs do.

X2. Where are they? And, doesn't ISC do it's job to control idle?

Yes. Not sure about when an upgraded head gasket is needed but I have seen evidence of movement of the head on even 270 tuned 998s. When I took head off one, there were not distinct clear sealing lines from head gasket. I could tell the head had been moving around on block surface. I was...
