No problem Gordo!Just finished the longtubes and exhaust, going to be doing the tf top end kit, 75 mm tb, 24lb injectors, fuel rail, 373's, and so on, but yes future plans are to boost, I just wanted to see if it would be a problem running a big pump now, thanks for the quick response oh!
You're welcomehahaha, ya got that right, its only my nice weather, weekend driver anyways, fuel mileage isn't a big deal, just wanted to make sure I wasn't going to open a can of worms with the 255 pump, thanks again Oh, your a big help
I've heard it before, but I'm not sure that I subscribe to the theory that the bigger pump creates any sort of a measurable fuel heating problem. I think it's mostly just speculation, because lots of guys run 255s on the street without any problems.
I agree that a 255lph pump can't produce enough heat to affect the fuel, but the very large pumps (for 1000hp and up) can easily boil the fuel if used on a street setup without a controller of some sort. They can even implode a gas tank that is not adequately vented. Those things move serious volumes of fuel.
You're right Noobz, all that fluid flow does generate heat. The pump itself still does contribute to the heat soak of the fuel system. General rule of thumb is if the pump is uncomfortably hot to the touch, it's too hot and the fuel is prone to vaporizing.
Dudes... it's not the pump that creates the heat. It's running all that fuel through the engine bay, by-passing the fuel regulator through the fuel rail, and returning to the tank... over and over and over...
I do agree though, that the pump should not be matched to your current setup but instead to your end-game setup. If boost and 300+ RWHP over large-ish injectors are your ultimate goal then yes... swap the pump just one time.
NOBODY who's running a Mustang should ever run a 190L fuel pump unless it's a HIGH PRESSURE 190L fuel pump.

And why should you NOT run a 190?Dudes... it's not the pump that creates the heat. It's running all that fuel through the engine bay, by-passing the fuel regulator through the fuel rail, and returning to the tank... over and over and over...

He's explained it before. I think he has said something about the 190's being more prone to messing up and jumping up to ridiculously high pressure. I can't remember completelyAnd why should you NOT run a 190?
Damn damn damn...
I hope mine was a high pressure one.

IT DOESN'T SAY
I gotta hear this.
If I ever do run boost I would want a bigger pump anyways just to be safe so we're good!From what I can find, the pump in that kit is a Walbro GSS242. It's low pressure.
The high pressure pump is GSS341 and it's not generally marketed for the Mustang. It's marketed for the probe.
All is not lost however... So long as you don't run boost.If you get to the point where you want to then I would suggest changing your pump.
