I assume you are asking about the HPFP (high pressure fuel pump) and not the FASS air removal system.

you can get a HPFP to run in conjuction with your stock fuel pump, or you can get one that has a higher volume and replace your current stock pump.
the good thing about the HPFP is it is rebuildable, and adjustable. Airdog also makes an upgraded pump only option.

 

Sorry about the confusion,but i was taking about the fass or airdog.

 

Don't be confused...

The 'fass' system or AirDog, which ever you prefer, is an air/water seperator, fuel filter, and super pump all in one.

With either of those you can eliminate the fuel filter bowl, sump the tank, and get rid of the stock pump.

Arent the air dog units low pressure high flow pumps? And still require a high pressure pump? Im pretty sure I saw that. Which means with an air dog, youd still need to spend more $$$ on a high pressure pump.

 

You are correct.

 

By 'get rid of the stock pump' I meant to replace/upgrade it.

Throw in an extra pump, filtration, whatever... keep 'em happy.

 

I found this old tread and was hoping for a update?
I just did the hutch / harpoon mod and I have a carter lift pump that IndyF350psd hooked me up with and was wondering how many of you guys running a lift pump have it before or after the the pre filter baldwin1212. And how long have you been running this set up now? I am running a stock pump with205k on it and I don't have the $$ to change what I have so I am thinking that adding the lift pump it might buy me some time.

 

I had been running a lift pump BEFORE the pre filter for about 5 yrs and even with my Walbro GSL392 up until July of this year when I replaced all my fuel supply lines with 3/8" ID braided hose. I found I didn't have a need for the lift pump anymore. IIRC, Clay is running a stock pump with no added lift pump and is also using 3/8" hose from the tank with excellent results. I believe with a good free flow on the suction side of the pump, the lift pump is not needed and NOT PRESSURING the the filter allows it to work better as a water separator as it was intended.

 

I'm running mine before the filter (not a baldwin 1212 though) and it's been on about 5 years.

 

If I had a little more faith in my stock pump I would try it without a lift pump but I don't trust it. And Roland I never gave any thought to the fact that when pushing the fuel though the filter it won't sep water. Good point. For now I am going to try it and will use it before pre filter thanks Guys.

 

Are still running a stock fuel pump with the Carter?

 

You'll be fine with a stock fuel bowl. Since I did a fuel bowl delete at the same time, I no longer wanted to pressurize the pre pump filter.

 

DIY pre-filter (30micron), H/H/ mod, and NO pre-pump here, for last year.

 

Yes I am running the stock pump and filter. I added the lift pump because of the pre-stock pump filter.

 

I am also running the same set up as Clay.I have had very good results.I am now looking at running duel factory pumps.With the filter set up I have I can run the pumps parallel to each other,not in a front to back setup.this way the fuel will flow through the filters the right way.

Anyone have a good stock pump they want to sell????
