Hello,

Im still a little confused about fd fuel setup. Please answer the questions below and help me out. Thanks

1. If i use the 850s as my primary injector, can i use id 2000s as secondary? Will this cause any issues with power fc or other conflict.
2. Based on the photos below of my rail. Do i need to order the 11 or 14mm id2000 injectors?
3. What rails are these?

Thanks again

 

Fuel rail

 

You might have to measure the opening of the fuel rail. That will be the only way of knowing for certain. Mine are similar and I have the 14mm. Yours may not be the same though.

 

Can anyone else chime in please? Especially #1?

 

Absolutely.

You just need to adjust your pfc for the new injector sizes.

Looks like a KG Parts rail. You can use 850's in the primaries but I'd advise against it as it takes a considerable amount of datalogit tuning to make it all work smoothly and also get proper AFR's in your cruise and idle. Isn't really worth it for just a little extra fuel. If you really need bigger primaries, there's ID's now which are a better choice.
