on my s4 turbo II I noticed the back of the fuel rails (stock FPR side) are smaller (M12x1.25) than the front side (M14x1.5) but I'm wanting to mount my Aeromotive A1000 regulator on the drivers side of the engine -by the hoist loop- facing out. Can I feed the fuel rails from behind without major consequences?

 

can you clarify further what you're trying to do? maybe draw a crude MS paint diagram?

 

ok sure thing, i know the direction of feed is normal for the primary rail but the secondary rail would be reversed

 

I don't see any problem with that setup.

 

the stock rails flow in reverse on the RHD cars anyway don't they?

 

now that you mention it i do believe i remember reading that somewhere along the line. that's great, thanks guys.

on an unrelated topic do you know if there is a copper washer for the oil pressure regulator on a s4 engine? I cant seem to find a washer that size in my parts bins and don't remember there being one to begin with. it would be a rather large washer i cant seem to find one on Atkins sight or anywhere..

 

nope just the water

 

Thats what I was wondering I have a s5 jdm motor and I am ready to hook up the fuel lines how do they get ran.

 

what?

 

just the water sender has crush washer. sorry
