surge tank lift pump??

Postby bossman » Thu May 01, 2014 1:42 pm

Hey I'm currently putting a 20v 4age into my ae85 and I'm trying to sort out my fuel setup.
I brought this pump as I was recommended it for the lift pump but then looked it up on Google and I'm not too sure about the flow rate. I was told it was 130ish lph but then looking at this the working flow rate is about half that.
https://www.pegasusautoracing.com/produ ... ?RecID=8...
From that link "Maximum fuel delivery 32 gallons per hour at free-flow. Maximum pressure 9 to 11.5 psi. Typical flow 15 gph at 5 psi. 1/8 NPT female ports. Ground wire allows easy installation in positive-ground applications (most Facet pumps ground through the pump body). "
What do people think? Has anyone used a facet pump? Or is there any other pumps you could recommend?
Thanks

Link is broken so can't see what pump you are looking at.

How much power do you think you will be making? And what sort of racing are you doing?

Just a factory 20v blacktop so not much power.
Mostly for a daily driver with maybe a couple of skid pad days.
Sorry about the link but most of the info is there anyway try this one

Any real need to bother with a surge tank setup? Just drop a decent in-tank efi pump in and do your skid pad days with a tank that is closer to full than empty? I wouldn't expect drifting to generate the sustained high G loads that leads to fuel surge if the tank has even the most basic baffling in it.

ae85 tanks have 0 internal baffling so anything below about 1/3-1/4 of a tank it will surge, more so if turning right iirc.

lift pump only feeds the surge, you will need another pump to geed the rail from the surge, unused fuel (most of it) will then go down the return back to the surge then once thats full back to the main tank.

Use the one you've bought for the lift then a VN Commodore VN 8/88 - 10/91 pump for the feed to your injectors. http://www.ebay.com.au/bhp/holden-commodore-fuel-pump.

At this flow rate - typical flow 15 gph at 5 psi - you'd have to use more than a tank and a bit of fuel every hour and I don't think there'd be many 4AGE's around that would do that....
See ya
