When i make a hard left turn and punch the throttle it seems like i lose fuel pressure and the power falls on its face like it stalled. im thinking fuel pump and if so will a S4 fuel tank work in a S5? My S4 tank is in better shape.

 

My old sentra did this too. Dump the fuel, drop tanks, wash tank, new filter, possibly new pump, clean the lines out, install, clean injectors if you want BOOM!!! Zoom zoom

 

the filter for the inlet on the fuel pump is most likely the problem

 

If.you have battery in factory location(engibe bay behnd.headlight) make sure the battery is tied down.and it not.hitting.the powersteering pulley. Look for pulley marks on the battery. My car used to do whT you explained.

 

Sock filter on the fuel pump, most likely. Battery tied down as mentioned, possibly corroded baffling in the tank, but most likely the sock filter.

 

My s4 did that when the gas in the tank was low.

 

this isnt a turbo swaped na car is it?

 

Yes, it will.
The S4 tank is a few gallons smaller (16gal. v. 18gal.) but I prefer the bulkhead electrical fittings on the S4 to the S5's weenie little connector (the bulkheads are not interchangeable without a lot of work).

 

Since the tanks are different size you will need the Straps for That particular tank for the installation.

 

off topic but...

I find it funny that my S5 has a larger gas tank than a lot of pickup trucks.

 

This one is a stock gxl and i mean stock other then suspension done last week. 203000 miles swapping stuff little at a time from my 88 swapped gtu i have a kid now so time is limited. Thank you for the replies and clokker bulkhead is the whole fuel pump assembly well at least he top of it?

 

Yes.
