Fuel pump and injectors

[Rob]

If i install the new fuel pump and injectors with no fuel controller will it run messed up ? what will it do will i need to do anything ?

Adding just a basic upgraded fuel pump (150lph) should be ok. With larger injectors and/or huge capacity fuel pump, fuel control WILL be necessary. You will need an AFC and Adj. Fuel Pressure Regulator.

What about a 190 lpm fuel pump

 

[Rob]

yes what about the 190 fuel pump ??

Put a 255LPH Walbro in the car on the stock system without pump rewire and it ran just a little rich at idle... Don't upgrade injectors without an AFC, or some sort of fuel management or the car will barely run at all if it'll start.

will i need a Fuel Pressure Regulator for the 190 pump ???

will a 255 pump alone make the car run too rich?

With a 190 pump, you won't need an adjustable regulator. A 255 will overrun the stock regulator and make you run extremely rich.

would a 190 be able to support a big 16g later on? when all other supporting mods are in place.

It should support a big 16g fine unless you plan on running insane boost. I don't even know if big 16g will make enough hp to over do that pump. I would say it should be fine though

awesome. damn i'm glad i didn't buy a 255. that would have cost me more money and more problems.
