fpr vacume pipe

[s3welshy]

hi all i did the n249 removal yesterday. as i was doing it i noticed the vacume pipe to the fpr was snapped. i replaced it.
what would this do to the car?

thanks.

Fuelling would potentially go lean under boost... not a good place to be... these FPR's are rising rate regulators... 3bar plus boost in this case... lack of fuel pressure under boost will mean fuelling can't keep up and go lean which melts engines... literally

not good. its repaired now. hopefully will be ok.

thanks for your knowledge.

Can the vacuume pipe be replaced with 4mm id silicone hose ?

Think I have used 3mm ID for the FPR... just measure the ID of the OE pipe to be sure, I don't have my car handy to check...

sound thanks mate,so would 3mm Id do all vac stuff? Like under manifold and that ?

I would use 4mm for the DV and boost gauge (if you have one).... you can get away with 4mm I think on the fpr but from memory its a loose (ish) fit on the fpr... secure the hose with small cable ties rather than clips

4mm was a nice tight fit on mine.

I used 4mm as well it fits snug but also used cable ties for extra security
