Thread: Fuel pump options

I want to upgrade my stock pump.
I was planning on just doing a Walbro and call it a day,as I have had good luck in the past with them....,but I see there are alot more options out there like AEM,Aeromotive,etc.

School me...Please share your knowledge,and info regarding this. It is going on a VE ,but I would like to make it overkill in case it gets boost or juice later
Thanks

I went AEM 320lph E85 pump. My tuner guy has gone as far as 500whp on S2000's with it...

The AEM are great, also have used the Walbro 255(currently have one spare) both will do the job.

i personally use the aeromotive stealth 340 on everything i need to put a pump in

Walbro 255 is def the pump to get if you want it cheap and simple

Handles my < 300hp VE-T with E85 just fine.. 2½ years since install now, and sounds just like the day i bought it

Walbro sells an E85 model now and they also have the 400 series with high flow rates. Any of them are fine, just be sure to get genuine products. I do like the AEM 320 lph E85 pump and will be running that when I make the switch to E85.

i forget specificallly which one i got, but i got it off of Mark....reading the reviews of it, plenty people like it. & rave about it...



my only concern is that it seems to pull MANY more Amps than the stock one does, or then a walbro does...so i may have to run new wires from the relay to power the pump....im afraid it might melt the tiny stock wires since they are like 22g or smaller

I thought this also, I queried my mate who did my loom( u12 KA24-P11-144 SR20ve) he said it would be fine and it has. But if battery hits 11.5 volts no go...

Yep, my Walbro 255lph melted the stock wiring after about 10k miles. Was running 26+ psi boost at times. I would suggest a fuel pump rewire if you upgrade to 255lph or higher. If your wiring goes under boost it could take your engine with it. I did a write up on this over on G20.net about it.

Pumps @ Idle
Stock G20 136lph - 2.9a
Walbro 255lph - 5.6a
AEM E85 320LPH - 11.3a

Good to know @Y2KG20 !

I might rewire my fuel pump then, seeing it pulls x2 the original amperage.
