Fuel pump replacement
I hope RED/Random/Yam can anwer this and I dont want to hear from someone that the ecipse GSX pump works either cus its different.
Replacement in tank pump for the new beta returless system in the 2001+ Elantras. Does anyone know which one will work or what the stock make and model is? I would rather use a replacement pump than add an inline pump to suypply fuel for a 75HP jetting of the NX system.
Thanks.

what about the walbro?
You can try that man... Im not sure of the differences between fuel pumps in the NEW betas tongue.gif wink and the old non gt cam bastards
Im pretty sure walbro has one
Let me do some quick research...

SCCA,
do the new betas trim the fuel pump with voltage regulation? In a returnless system, the pressure will probably be fairly constant for most of the operating conditions. Returning fuel pumps are more about flow rate, returnless pumps are more about pressure. Although I wouldn't be surprised if Hyundai used the same fuel pump. sad.gif
I'll dig around hmaservice and see what I can come up with.

The 01-02 elantra and the 03 tib use the same pump setup. Here is the interesting part.
There is a fuel pump, assist pump?, and a fuel pressure regulator all located in the tank along with your fuel filter. We have yet to do one but it appears you can get access from under the back seat cushion.

Now this is closer to what I've been looking for. I knew the FPR/Filter/Pump are all located at the tank. Now thing is that I dont just need fuel pressure. I need the flow too. Otherwise I will not be able to run that 75HP jetting. Fuel pressure is nice but if there is not engouh fuel flowing through the system pressure will not stay up.

Also Are you trying to say the *main pump* is the same? My worry now is the assistant pump what is it actually there for? (probably to keep pressure up) Thats the one in which should be in the tank correct? (taking the initial suction) These are what we would call booster pumps in the Navy. If so thats the one that would need to be upgraded as well as the main pump.
Eventually I will be spraying this thing with a 200HP direct port setup. If I do the inline pump it will not hold. Pressure will mean jack with a 45gph fuel pump. smile.gif
I have already cheacked HMA and the part numbers on the new elantras and the old ones are different.
And I am not about to cut into my fuel tank to add a *universal* fuel pump. Nor will I cut and paste my car. smile.gif rolleyes.gif
I have been lazy in trying to look at the fuel setup by looking under my back seat. I've tried taking that thing out once before and its a PITA.
I would like to just take it out once and keep it out but I dont think my 11 month old daughter nor my wife would appreciate that too much.

It almost sounds like the returnless fuel system is just like the return fuel system, except that the regulator, pumping, and bypass all happen right at the tank. I'm wondering if there is some sort of electrical regulation done with the booster pump to compensate for higher loading.
I'd like to see the diagram and wiring, but have been too busy today to dig around HMA.
Seems the car engineers are finding new and exciting ways to make our upgrading more difficult.
good luck,

When I get to work tomorrow I will look at the assist pump closer. Maybe I will even order one just to see what the heck it actually is. I have an annual return I am doing in August I'll just return it after I look at it.

What about both pumps? Which one is in the tank and could one be replced with getting rid of the other? Meaning remove both pumps and install a new in tank pump. What would that do to the fuel pressure, would I need a dead dead regulator? Or is that the kind of regulator the returnless system uses anyway?
