Fuel Pump Limits

Blackcoog · 08-01-2007, 08:59 AM

Anyone have any idea what the stock fuel pump limits at? I keep adding fuel up top but it doesn't seem to help. Over on CEG the stock pump was stated to handle about 300whp. Anyone else running FI on a stock pump or aftermarket pump? I have a walbro 255 pump sitting on the shelf so I'll drop that in quick before the dyno.

I dont know about the stock pump but the focus svt pump is good up 425whp and direct bolt on if you are returnless. (so i've read)

I'm running 350bhp and needed an "In-Line Fuel Booster" to supply enough fuel at max revs.

I have a return system so the walbro pump I have is the way to go. For the returnless cars the focus pump would be the one to go with.

their is slight "Modification" to make that walbro pump work FYI unless you have already had the pleasure and know what to do.

It looks like the connector needs to be swapped over so it will plug in. I'm sure I'll figure out the rest when I pull it. From this how to it looks like that is about it: How To: Walbro pump install on RETURN style cars

I hope your dropping the tank. The major issues is mostly with the depth of the pump itself.

I am running my 3L turbo with SVT cams and I range between 7psi -12psi and I haven't outflowed the stock fuel pump yet. I bet I am very very close to borderline though. Good thing I have a wideband! :D Is the SVT fuel pump the same as the cougar v6 fuel pump (155lph)? I have a 190lph fuel pump from one of my return style contour parts car, and I think I'll be dropping that in to be safe. Do you guys think a 190lph fuel pump with flow enough for 375-400 at the wheels? Anyone know how many liters per hour the focus fuel pump flows?

All I know is turbo19psi's booster pump went on the fritz and his car was on the edge of detonation at idle it seemed.

I have a booster pump as well and it seems to be fine. Even after the tune it still runs rich. If I can lean this thing out alittle more I know theres alot more power to be had. But for an everyday driver its fine
