No, there is not. I guess you could fit one inline with the fuel inlet pipe if you could find some correct fittings.

Does the WK2 have a fuel pressure sensor that you can monitor using the correct electronic tool?

I've noticed around the WK and WK2, Chrysler/FCA left schrader valves off fuel rails for a lot of their vehicles..... ....yet measuring fuel pressure is a vital troubleshooting tool.....
Don't know for a fact, but more than one vehicle does have a fuel pressure sensor to monitor/check fuel pressure using electronic tools....

It's not just FCA. Others are doing that mess so now a series of adapters are needed to perform a physical pressure test on the system. It's quite annoying.

Ah, I see now, so they aren't so stupid to not realize that checking the fuel pressure in the vehicle sometime during its life will be necessary. They simply made it so that owners can't check it themselves without spending a lot of money, and thus will just give up and go to the Dealership.........:mad:

Actually, its probably was cost savings, cheaper fuel rails and less parts, saves a lot more than just sending all the dealerships an adapter to check fuel pressure if necessary....

Bingo!

Actually, it's a common fitting that is found in most commercial grade fuel pressure test kits. Just makes a mess having to disconnect the lines to install the adapter. The schrader was sooooo much easier and cleaner.

Unfortunately a lot of fuel rails these days (including our 3.6 Pentastars) are plastic, they probably couldn't take the stress of the fitment of a Schrader valve without something snapping off.
