I have a Turbo on my Civic and currently have the 255 lph Holly fuel pump. Is it worth upgrading to the 255 Forced Induction fuel pump????

 

the pump you have should be good. If you are running a FMU set up I highly encourage you to get a inline pump.

 

Yes, with anything but a FMU the normal 255lph is fine. Like stated above, with the FMU you must have a inline (noisy) pump like the Bosch.

 

Thanks for the insidghts guys. What do you mean FMU (I know that sounds dumb, but I can't figure it out)?

 

FMU is a rising rate fuel regulator. It raises fuel pressure on a ratio, for example 6:1 and 12:1. The higher the number the higher the fuel pressure will be during boost, which is why a very high flowing pump is a necessity with the FMU.

 

I have been getting a code 43 (Fuel Supply system) check engine light lately. I have a B&M fuel pressure regulator now...maybe it is faulty. I am going to get the fuel pressure checked...anyways, could having a faulty fuel pressure regulator cause the check engine code? How do you know if your fuel pump has had the biscuit? Is there any check you can do to see if it is functioning properly (The car does run, but I get the check engine code)? If you have any sort of inight regarding this matter, please let me know.
