(not my picture)

Just bought a used JRSC kit and looks like I'm missing the above part. Can somebody tell me what it does?

Thanks

 

looks to be the adapter that bolts in between ur fuel pressure regulator and fuel rail. u may need it due to clearance issues on the fuel return line. it rotates your fpr so the return line doesnt hit ur intake plenum.

 

I see. But if I'm not running the stock JRSC FMU, do I still need that piece? or that piece needs to be there regardless?

Thanks.

 

He is 100 % correct and if you have it I dont see why you wouldnt use it .I did not have that part when I got my jrsc at first and had to bend the return line on my regulator it worked but it sure was a close fit to my intake with the return line .

 

If you click this link and look at the pic of my set up you can see how tight of a fit it was without the fpr adapter .I also have the LHT set up which probably didnt help . I have since installed the adapter .
