Dual fuel pump set up on factory sender....

[Lilmac]

Hey everyone or anyone. Was wondering if anyone thought this set up would be a problem to use on a factory sending unit ??? Twin turbo LS in a 84' Cutlass and i want it to look some what factory. This set up is already assembled and ready to go at $269.99 https://www.ebay.com/itm/TI-Automotive-900LPH-Dual-Walbro-F90000267-E85-Fuel-Pumps-Kit-System-1-400HP/282364399120?epid=570756034&hash=item41be3ace10:g:8NkAAOSwAaJaJwg7

That's a nice setup and cheap too! I'm interested as well because I'm currently trying to decide on a fuel pump setup for the GN tank I just bought. I've been looking at the Racetronix single pump units that come assembled on the factory hanger/sender, but a dual pump would be good insurance and can be programmed for the 2nd pump to activate at a certain boost level.
There is a member on here with a dual pump setup on his turbo'd LS cutlass. He told me the 2nd pump is set to kick in at 4lbs of boost. I will try to get in touch with him to get more info.

Good luck getting that through the hole in the tank. I have a 400lph Walbro in mine and could stagger in another if it were needed.

The problem isn't them fitting; it's the puny 3/8" outlet. Get a GN Racetronix with a 1/2" outlet.

I will be making the sender 8-an feed and 6-an return

Are those even real Walbros?

That won't matter if the outlet of the corrugated in-tank Y is smaller than the ID of your -8AN line. This will be the source of your restriction and probably some tuning and driveability issues. Your best bet would be to run one big 450 Walbro (from a trust source) in the tank, and have another with a surge tank for periods of higher fuel demands. Something like this: http://www.radiumauto.com/MPFST-Multi-Pump-Fuel-Surge-Tank-P271.aspx

Alternatively, as suggested, you can offset the pumps on the hanger. I am looking at placing in the stock location on a GN hanger, and laying another on its side and positioning it toward the rear of the tank - it'll look like a big L. Anyone who runs their car low on gas and exposes their sump/sock is an asshat. I don't race on less than a half tank ever.

Don't cheap out on fuel.

Racetronix's generally uses good Walbros. I had a few issues with them in the past but they generally make good quality stuff. the 3/8" diameter outlet is weird, though... going to all that trouble of dual pumps. That is like dual pumps for people who don't really need dual pumps.

Wait...what... why is the picture watermarked racetronixs?

Exactly.

But get Summit to price match it... at least they are getting their product straight from the source.

the outlet on all their pumps is 3/8, so 3/8 to Y barb on any of their setups to a 3/8 coupler to sending unit and out to an upgraded -8an line seems to be what all there kits have.... correct me if i'm wrong?? the picture looks like 1/2 but their own site says different with their line adapters also...

hard to think 6" of 3/8 line would be a restriction
