Ford motor Sports Fuel Pump Warning?

June 23, 2005, 09:54:34 PM

Deciding to what fuel pump to put in since I have to replace the gas tank because of a leak, and saw the Ford Motor Sports M-9407-C50 190 lph http://stangstore.com/Merchant3/merchant.mv?Screen=PROD&Store_Code=S&Product_Code=M9407C50&Category_Code=50INTAKE

has this scarey sticker on it:

" WARNING: This part has been designed and is intended for off-highway application only. Installation on a vehicle intended for use on public roads may violate US, Canadian, state, provincial laws and regulations.. related to safety and emissions..."

1) I would have thought the fuel pressure regulator maintains the amount of fuel to the engine and it wouldn't cause any emissions change just by having increased flow rate.

2) Since the stock (for 5.0 HO) is 88 lph, is there really much safety issue between 88 lph and 190 lph?, I mean if a hose gets cut that gas is going to be shooting out with either pump.

The HO conversion seemed to run fine off the 3.8L pump, I'm thinking maybe this high volume isn't such a good idea for some reason after seeing that warning!

Personally, I would just chalk that up to Ford covering their ass. I too believe it should have no bearing on emissions.

sounds like a generic sticker they blindly put on all performance items to as Joe said "cover thier ass"

My guess would be that it's never been EPA/CARB certified. Since it hasn't, it does not have an EO (or something like that) number, so it is illegal to use on a street car.

Oh noes!!!!111oneoen1eleven

The illegal fuel pump police are coming to get us! They're gonna drop our tanks and bust us! :D

Seriously, though.. yeah, it sounds like it might be technically illegal for street use, but do you really think they're going to check? I would think it's only a problem if you're one of those people who cracks easily and spills the beans at the drop of a hat..

*officer walks up, shines flashlight in your face* "You know how fast you were goin'..?"

"Yes! Yes! I was doing 89 in a 55, and I know it because of my speedometer modification! I pounded out my catalytic converters, and I've got an illegal fuel pump, too! I even ripped the tags off my mattresses 'under penalty of law'! Don't taser me..!"

:p

im still wondering what the benefit is from running a fuel pump as high as what you guys are talkng about. I still dont really get it cause the injectors will only support but so much presure anyway. Maybe its a peace of mind thing or perhaps its the thought that its upgraded to a level that is ready for other powerplant mods.

I thought that the SC 3.8L fuel pump covered a broad range of fuel presure for a 6 or 8 cyl so that plus 45 bux in cost was a lure i could not pass up.

well, for example, in my case with the turbo coupe

guys set the base fuel pressure anywhere from 37-45psi, and then under boost, every psi of boost increases the fuel pressure 1 psi, so say my base pressure is at 40, and im running 22psi of boost, thats 62psi of fuel pressure

not all pumps can support that much fuel pressure

I my case when I was spraying the "Nawsss", fuel pressure would jump to 80-85psi. The 190 didn't seem to have a problem..

Larger fuel pumps come into play also when you upgrade your fuel injector, so if you started with 14lbs ( which is what comes with a stock 5.0 bird) you only need to supply them with a 88 lph pump because the fuel demand is not that high. Now if I tried to run a 88lph pump to supply my 50lb injectors they would run the pump dry under full load.

The 5.0 SO's and V6 cars only got a 60 lph pump from the factory. Some Mustang enthusiast magazines claim that even the 88 lph pump is too small for a bone stock 5.0 HO. How much truth there is to that, I dunno, but when I replace the 88 lph pump in my T-bird, which will be soon because it's howling to beat the band (thanks Shawn :flip: ) , I'll probably go to a 110 lph pump, granted that it won't f-up the tripminder fuel computer. I rember reading on the old board that someone had a problem with the fuel computer not calculating correctly after either a pump change or an adjustable fpr swap; can't remember which one it was anymore....

you shouldnt have any problems with the tripminder, because it recieves signal based on what the EEC specs for fuel, rather than what the pump flows
