Fuel Starvation and Holley HydraMat

[gbrettin]

The Holley HydraMat might be able to help with fuel starvation, what do you guys think?

Yep I was hoping for the same type of solution, but then was enlightened by Charles below.

-the factory fuel pump resides in a "module". It is surrounded by the fuel filter, and then a canister that is *supposed* to act as surge protection. Obviously the canister doesnt do its job - probably because the majority of its displacement is spent on the pump, filter, regulator, etc etc... and its pathetically shallow at only 4" deep when the tank is more like 10" deep. At any rate, quite bit of modification woudl be required to make the factory fuel pump module accept a fuel pickup that isnt a compact little unit that attaches directly to the bottom of the pump and never leaves the confines of the canister.

-The fuel pump, and anything you would easily replace it with (AEM, Walbro, Aeromotive, DW) uses a standard in-tank fuel pump inlet attachment style that the Hydramat does not conform to. some sort of adapter fitting would need to be manufactured to attach anything other than a standard in-tank pump pickup to the bottom of the pump.

My predictions are that nobody is going to successfully implement a Hydramat to a 370z without building a custom fuel pump module/hanger that holds the pump higher up and gets rid of all the complexities of the factory fuel pump module. This would also entail running an external filter and regulator (custom return fuel system). Anyone is welcome to take this prediction as a challenge and motivation to prove me wrong! But if anyone wants to try and build a custom fuel pump hanger for their car, I sell and have in stock universal billet fuel tank flanges with electrical bulkhead connectors and threaded bosses just waiting for whatever custom bracketry someone wants to build and bolt up to it.

Needless to say I ordered a Road Race Pump setup from him

700 bucks for the 30" Hydromat, some brackets and a filter.... Hmmm, sounds like a fun project and DIY!

The mat is bested used with an external fuel pump from the look of things. You notice in most of Holley's pictures. It's a fuel cell that they're using. $700, just add another $300 or so and get the RRP from phunk.

Some reading you need to read.
