What are people running for fuel sampling? I have a male/female "dry break" style fitting that I bought several years ago from somewhere for the MGB (but never installed). However, the Miata has the following:

This seems WAY simpler. Thoughts?

I use the Pegasus unit but I'm freaked out I'll bump into it some day a get a gas bath. Its just a Schrader valve.

I have a Jiffy Tite valved quick disconnect tee'd into the main fuel line.

I have a mating male plug end on an 24" length of hose that I can plug in and pump to any given container.

Been on the car for something like 7 years without issue. Bumping it will not disturb anything - the plug end needs to depress the inner workings to release the valve.

I copied this kit with AN style fittings basically:

I think I have the older Jiffy Tite set-up.

I use the aircraft style /Pagasus . Never had any issues. I buy 3 or 4 at a time for customer cars.

My factory fuel rail has a schrader valve with cap right on the front end. A lot of cars that came stock with EFI have the port for testing the fuel pump.

If you make a rail from some billet aluminum something, it seems easy to add a 1/8NPT -> Shrader valve on the end and cap it.

While convenient, having the port in the engine bay (where it’s hot after a session) is an incident waiting to happen. Put it in the trunk away from heat, etc. and you be just fine.

I can email a pic of my setup if you’d like....easy, cheesy......the dry break port was connected to a bulkhead fitting in the rear valence. You’ll are the tech types much happier too.

Dayle:

A picture would be great. I am in the process of laying out the fuel lines for the pumps and filter, etc. in the trunk.

I used one of the Pegasus ones myself. cheap and easy, especially since the car has 5/16" fuel lines factory. I Tee'd it off just past the fuel filter en route to the fuel rail. factory fuel tank in the rear, so there were no exposed lines or other plumbing in the trunk. Exhaust and all hot parts are also routed on the other side of the engine bay from the fuel and intake area, so I felt it a safe compromise.

... and thus far every time I've had a fuel sample taken, tech informed us as soon as we rolled across the scales. asked us to pop hoods and make the sample ports available, and then it took 10-15 minutes to get everyone weighed and start taking fuel samples. I did not feel rushed to produce a fuel sample on a car that had just rolled off the track and was dangerously hot.
THEN add the tech standing there with a fire bottle while you took the sample.

I do a lot of whining about some of the stuff in my area, but the tech guys have this procedure done well, IMO. Kudos to them for making fuel samples as safe and painless as possible.
