What do I need to use a supra fuel pump in my 99 eclipse with a hahn stage II? What year and modle supra pump will fit my car? What if any modifications do I need to do in order to use this pump? Please help....if anyone uses this pump or knows of any other intank pump that will work instead of the inline and stock that is quite and will work with higher boost please help me. If there is already thread that answers all of my questions please let me know. I appriciate all the help.

I am using this in-tank pump with my HRC stage 4. I didn't personally intalled the pump, so I really couldn't tell you what to modify to make it fit. I actually got a hold of a GS-T fuel tank cover and harness assembly, so installation was not a problem.

For fuel control, you will need an S-AFC or some sort of fuel control to lean the fuel system, otherwise, you'll be running VERY rich. The Supra fuel pump really provides enough fuel pressure/volume.

I know this is an old question...but I havent found the answers I needed. I hate the hahn inline pump...it is so damn annoying.

I know of no in-tank pump that can safely and consistently supply enough fuel at the fuel pressures required for 9 psi boost on stock injectors. If you want to run 6 psi or buy larger injectors, then go with in intank pump. Otherwise, you still need the HRC inline. The big deal here is you are asking the pump to supply alot of fuel at 110 psi of fuel pressure. Few pumps can meet those fuel demands at those pressures. The Walbro 255 Hi-pressure pump barely works for that duty. You either need to keep the fuel pressures lower or keep the inline.
