Default 3mm shut off valve

The P20 feeds are 3mm lines, jetcat sent 4mm shutoff valves, is there any 3mm shutoff without halving to make a reducer from 4mm?

I don't know if Todd has a 3mm valve or not.

Raptor: Is it 3mm coming out of the pump? My Wren 44 uses 3mm hoses... but it's 4mm from the pump. So... I run 4mm to the valve, and filter... then I use a 4mm to 3mm Festo right at the engine.

my P20 came with 4mm to 3mm reducers. I came off the fuel tank with the 4mm tubing to the shutoff and then to a reducer.

afaik, festo do not make a 3mm valve, which is why Wren sells the special 4-3mm adapters for the valve, see "plug-in reducer" about half way down the page http://www.wrenturbines.co.uk/access...sto-connectors

Your right... Brain fart... I was thinking 6 & 4 , not 4 & 3... Can't say I've ever seen a 3mm valve..

Only problem with that is... the seals inside of it may not like Kero.

Agreed. There isn't much out there. Until something becomes available a 4mm valve with increaser then reducer is the best solution.

Why not trust the solenoids? From what I have seen an extra valve causes more trouble then it helps. Removeing the valve would eliminate atleast 3 connections points(potential leaks) in this case, free up space and save some weight. (I know this wasn't the question)

Here in the USA our governing body requires it. See point #8.

This is the one I've been using on my Wrens for years. You have to heat up and stretch the tubing to force it over the 4mm nipple. It forms a tight seal and works great.

I did not see any 3mm stuff except for a straight connector, and that was 2 weeks ago when I bought some festo fittings
