wana12v

looking for opions on a high performance fuel system for my 12v. My stock lift pump is ticking and I already have the overflow shimmed for more fuel pressure, but with the amount of fuel this injection pump demands I want a big electric. An a1000 aeromotive would work but I heard it isnt the best for longevity. What does fass offer? any other ideas. what are some of you high hp 12v running (600+ hp)

FASS has some pretty serious systems out for the high demand 12 valve applications. There are two in particular - one at 45 psi and the other at 50 psi. Both of which will certainly supply all of the fuel you'll need to achieve that mark of 600. You could actually go a little smaller. The Aeromotive are just plain loud and they're not designed for diesel. I ran one for a while and it sounded like a dang meat grinder and would leak fuel during the winter. Got the job done but my FASS is much quieter.

600 is not my end goal so I need a setup that can feed a 13mm pump and be reliable day in day out. I think the fass is the way Ill go I just wanted to hear what the really high hp street driven 12v guys were running.

There's a member over on TDR (Reb.B) who's running 893 HP using a Walbro system. He replaced his FASS 95, since it was not supporting 600 HP. The Walbro systems are definitely worth looking at. I'm running a kit from Alternative Fuel Solutions (http://www.altfuelsolutions.com) that's working awesome.

With all due respect, the Walbro GSL-392 flows pretty much the same as our 95 GPH pump. If the FASS was not able to keep up, something in the set up was causing issues and needed to be addressed.

I have seen our 95 GPH kits work just fine on 600+ HP applications.

I would eye the FASS 150/90-1010@45 PSI.....this is our strongest setup for high pressure and flow (This pump can push over 100 PSI if needed). And that is 90 GPH @ 45 PSI.

So what is the price on a FASS for my setup, lets say not going over 600 HP.
now my fp drops to cero at wot. The 95 GPH i suppose

Check on the "Links" above. I think there are a few DTR vendors that sell the FASS systems.

i have a FASS system on my vp-44 pump which is rated 150GPH@20PSI but i am going to be doing a p-pump conversion and it requires the higher PSI that my pump does not put out. So i will have to modify mine or replace it with another pump or something but i will say i have had the FASS for a long time now and had nothing but good kodo's for it.

Here are the MSRP costs of the kits for your truck but check with a dealer for exact pricing:

FASS 150/90-1010@45PSI -- 769.00
FASS 95/95-1010@45PSI -- 739.00
HPFP-90-1011@45PSI -- 539.00

IIRC Storx, you have a 150 GPH unit....thus the issues with putting the pressure up to 45 PSI. Correct?

For those with the 150 units, looking to go to a mech pump, is the only way to go to a higher pressure to purchase the 1010 setup, or is there something that can be done to the lower pressure ones (1008?) to get them to a higher setting?

Diesel-Dan

OK.....here is another explanation:

PSI is a load on the motor
GPH is a load on the motor

The more GPH you pump can flow, the less PSI you can get out of it before you over load the motor.

The more PSI you pump can put out and handle, the less GPH your pump will be able to flow.

You can use a larger motor that is stronger, that can handle more load (Meaning it can survive at higher amperage because of the added load)

Here is the deal with the 150 GPH FASS/HPFP. When Brad originally designed this pump…there was NO applications that required anything more than 20 PSI (Our 12V kits worked with the stock mech lift pump). SO he built this to suit this application. We didn’t even have a 95 GPH unit until 2004…I think. The motor and pump are set up to run a max pressure of 25 PSI before amperage is an issue. Not saying that the 150 can’t push 45 PSI, but motor life will be reduce due to accelerated brush ware……kinda of like tuning up your Cummins……do at your own risk.

NOW with the 95 GPH units, the initial load of the pump is reduced. The gear is taking half the bite of the 150 Gear. (BUT the motor is able to spin faster due to less load, this is why its 95 GPH instead of 75 GPH.) SO this means that you can load up the pump with more pressure before motor amperage is an issue. The 95 GPH max pressure is about 80 PSI. I believe this pump will work just fine in applications requiring pressure and moderate flow.

Now the 90 GPH@45 PSI and the 180GPH@45 PSI are the units with the larger, higher amp motor. This motor is built to run a very long time at higher amperage (Load) with out burning up. This pump set up will MOVE some fuel at pressure. In other words, you will have well more than enough needed to supply anything you can throw at it. Those are flow ratings at the pressure listed. These pumps (Especially the 90 GPH units requiring higher pressures) are GREAT for WVO (Waste Vegetable Oil) applications. Max pressures on the 200 GPH units are 80 PSI. Max Pressure on the 90 GPH units is about 125 PSI.
