Microtech FPR Vac lines

[paul3944]

Hi All,

What have the S5 owners with an LT8 done with the two vac lines that come from the fuel pressure reg :confused:

Also did you just cap off the lines from the stock turbo :xconfused

Anyone got an idea ?

you need to elaborate a little more,   you need a vacume line to fpr to rise the rate but i assume you know this

[paul3944]

Sorry,

There are two vac hoses coming from the end of the fpr, emissions is 90% removed from the car.
Dont know what to do with these left over vac hoses :3Confused

Paul where your showing two vac lines near the fpr one of these will be the fuel return line. Any manifold vac line will do for the fpr and don\'t forget the fpr is on the return circuit to the tank, sorry to state the obvious but i\'ve seen people pipe the pump to it on a number of occasions.

Thanks for the reply,

I\'ve redone the drawing the two hoses are defo vac, 3.5mm black silicone and go into what was left of my emissions rats nest.

I\'ve marked on the drawing where the fuel return line is.

to ask the obvious - whats that ^ ?

Why have you gone this route? You just needed the fpr no lines going to stock fpr just put uprated into fuel return line put vac/boost source to new fpr and turn rail pressure up!
