290l fuel pump question on standard RA
Hi all
I have bought a 290l fuel pump from scoobyworx and after some reading I believe the standard fpr is not suitable as this will not return the fuel back to tank and cause over fueling issues.
Car is a v3 WRX Type RA with performance panel filter and 3inch sports cat back zorst,(standard yellow 440 injectors).As I intend to up the power in the future with the help of an ESL daughterboard this is why I went for the 290l,plus it wasn't much more cash than the 255l
I was going to buy an aftermarket fpr as I think this is my only option,then I saw this ad on SN http://dccdpro.com/zcart/index.php?m...FfOhtAodpzUAuQ
Would this do the same as a fpr? Is there any other options I can consider?
Cheers Rich

I've bought the 255 pump from scoobyworx too for my T2000. I didn't take the 290 as I'll not be going near 350bhp any time soon. I'm using standard injectors and TD04 turbo as well but I have ESL. I bought it as a service item really as the car still has the factory pump which is nearly 18 years old now. Are you saying the higher capacity pumps cause fuel return problems?

I understand that, I'm just curious as to how the higher flow from the pump would cause over fuelling and return problems when it's only the FPR that can affect the injected quantity if the pressure is changed.

Aftermarket FPRs are manual set at wanted pressure so yes if you buy aftermarket and setnit to OEM level it will be ok,but it will work the same with OEM unit.When remaped you will probably want more boost and OEM fpr will have to be changed.
So when changing to better fuel pump new fpr is not a must buy item.

Once I get my new pump I'll tell you what happens. I have ESL and a wideband so I'll do some fuel logs with the standard pump and some with the new pump without adjusting anything and using the factory FPR.

Oh and getting a wideband is a must for when you get ESL installed. Self mapping would be impossible without it. I literally stole a brand new Zeitronix ZT-2 kit with the LCD display on eBay including genuine optional sensors etc for £100! I highly recommend it from my experience using it.

Sweet, thanks. Would 440s be of any benefit to my car that's still using a standard TD04 or would they be a waste of time? Like I said before, I have ESL and have been self mapping for most of a year now.
