I have an empty hole to put a gauge in and a want to put a gauge to monitor rail pressure. what gauge are you guys using cause i haven't seen a gauge that goes to 20,000 plus but then again i havent looked very hard. just wondering what setup you guys are using to monitor it.

 

I think this is the one I am going to order.

They have it in black as well.

 

i do believe isspro has one also....but only one series...(IIRC...which ever one has the 'computer box' thinger..)

quadzilla has a rp gauge also, but that doesn't really fix your 'empty hole' problem...its also a fair bit cheaper than the others.
