04 gu bus...

Quick question.. Do I have to run the hrd nylon hose for my boost gauge or can I change fitting on back of my gauge and run vac tube?

I have teflon except where I "teed" into it I used small pieces of vacuum hose
For acuracy I would use Teflon/nylon hose/tubing

My gauge is showing no boost at all.. Thought my gauge might had been faulty.. Hooked it upto my bike hand air pump and I can see the dial moving so gauge is working ok.. So must be leaking boost either out of the inter cooler or inter cooler piping.. Just removed inter cooler nw and gona check for leaks.. What's the preferred method? Tape one side dip it into water and use air pump and look for bubbles?

Pretty sure this intercooler might be stuffd..i dipd it in water i couldnt see much bubbles.. filled with water n if i turn intercooler frm.side to side i could see a little bit of the water seeping through... this would mean its got to be leaking somewhere ayy..

Chances are being an 04 model it will be leaking, tape up one side and use a bike pump to pressurise it.
you'll see the bubbles , dry with a hairdryer before installing

Cheers 3dogs.. id say shes leaking.. might have to jump online and have a look for tigged up replacement... otherwise go with that one frm the link posted up earlier.. thought if it were leaking i would at least get a couple psi through the gauge...

I dont think mrs has a hair dryer only a ghd thingy... so im just drying it out in the sun...

Quick update.. i couldnt see much bubbles if any when i was checkn intercooler for leaks but was still convinced she wad leaking.. anyhows checked everything and then noticed this fitting had no hole in it... what the? Anywayd changed it over nw im getting boost.. only thing is its saying im getn way too much... if i giv it the berrys i can get upto 25 pound.. as soon as i change gear it drops to 5-10psi... when i rev i can get upto 20.. but it normally arnd 5-10psi when im just cruising... is my gauge reading right? Shouldnt i be getn limp mode with that much boost? Wanted to get quick comparrison with boost/egt readings befor i block egr n setup dawes n needle valve...

Heres couply pics of new dump n pyro...
Still might wrap my dump pipe with some exhaust wrap to help keep temps dwn plus ive still got half a spare roll just sitting here in my garage... egt temps usually arnd 2-300 degrees...

Whats standard boost on these things? 15 pound? Full boost i can get 25psi.. is this normal?
