Has anyone installed an aftermarket fpr in their cls, if so how?
Please Help, the one i got has an inlet , outlet, and vacuum.

 

As all FPRs do, that is the way an FPR works. Adding one for no reason or with no concept is ludicrous.

I still ask, why add one??

 

Actually they make FPRs for cars that don't have a fuel return line, like Volvos for example.

But yeah, why the hell do you need one? Unless you're going turbo or something. I guess if you're upping your nitrous shot maybe it would help with that?

 

can you help me or or not? you are correct jrock

 

I want to install a turbo system, where can I find the engine??...JK

But honestly and as previously stated, and FPR is worthless to you even with nitrous. How are you going to tune it, is the fuel pump enough for what you are doing, etc??

But if you must do this then look into tapping the return line. It is the smaller line with a spring clamp on the stock FPR.

Just get some same size HP fuel line
Remove the stock return line
Install a section of the new hose to the stock FPR
Connect this to the new FPR inlet
Attached the stock return line to the new FPR outlet
Now tee into a vacuum line and use this as the FPR vacuum source.

I'd mount the new FPR to the firewall. But again, how will you tune it, will you use a scan tool or a fuel pressure gauge. But this is a pointless endeavour IMO...

 

thank you, finally, someone helpful, took you enough comments to finally help me, scalbert , i just like fucking with things, i have to see what you are saying with my own eyes!
