Xr6 Turbo Fuel Pump Replacement

[msutherland]

going to replace my fuel pump on my ba xr6 turbo ute, bit of a mission. im relacing it kuz it gets quite loud after uv been driving for 70km+ the mechanic said it kuld sh*t it self anytime so better to replace it.

my problem is that I dont no if the previous owner(s) have upgraded it or the injectors. the guy I bought it off seemed to think id had been upgraded buy the previous owner. but not a definate.

im just wondering if I buy a standard replacement and it has had upgraded injectors, will it effect the peformance and the motor running to lean or rich? or if it hasnt had an upgraded fuel pump or injectors and I put in walbro one will it again effect the peformance and/or make the motor run to lean or rich.

whats my best option???

cheers

Different or drilled injectors would mean a custom tune is in it. There is a fuel pressure regulator, but if the existing pump is tuned for and better than the one you put in it could under fuel I'd imagine?

Get it to a reputable tune shop if you don't know what you are driving. Recipe for disaster.

ohk thanks. and is there any way to tell if the fuel pump and/or injectors are upgraded just but looking at them? I also forgot to mention that 70% of start ups I kn smell fuel within the first 5 minutes of driving.
