The JCW kit has the correct valve (or at least mine did). One way opens to the distributor (system pressure), one way closes the line from the distributor so it measures control pressure. The gauge has to be on the WUR side of the valve to measure properly.

Dave,
Mine had a variety of fittings so I can connect direct to the dist/WUR or tie into the connecting fuel lines. I bought mine 5+ years ago so it could have changed but I doubt it. The 924 guys use the same kit and I've heard no complaints.

can you please have a look at what comes up when you enter that SKU on the JCW site, and let me know if the pic looks like your kit? I'm about to pull the trigger but want to be sure.
Thx

Dave,
Haven't forgotten you. Been in meetings all PM. I got the information from a catalog at the house, so I'll get it to you this evening. Can I send a Spanish porcelain sale rep your way? Just kidding.

I think this ZX123617U is the kit I bought 6-7 years ago, but on the site they seem to be using the same picture for both CIS and non-CIS kits. Mine has an open/shut valve on one side of the gauge T, which should be fitted on WUR side so when closed the gauge reads system, when open reads control pressure. It came with no banjos, only adapters to enable connection to different car fittings. It can be a pain getting the connection to the WUR inlet line in place due to it facing downwards, and lack of space.
A friend recently had issues with his WUR (50psi control cold), and wanted to start messing with its settings, but I persauded him to clean it first. He dismanlted it and ran it through an ultrasonic cleaner he used for clock repairs, and it went straight back to stock pressures and car ran again!

Dave and JP,
The picture is for the EFI tester instead of the CIS kit. The description indicates it has the valve and 6 adapters to connect between the FD and WUR. On my 928 the easiest connection setup was between the FD (center outlet) and the fuel line going to the WUR. The only fault I have with the KIT was that there is no carying case included.
Attached is a picture of the catalog page. Hope you can read the details.

The fuel pump you installed from "a parts car" MUST be the correct pump or your cis will not operate properly. You might also have another pump in the fender well or in the tank.

My CIS car ran for years with an S4 pump, delivering 75psi, so I dont believe there is a Special pump for the CIS cars. There is apparently a different spec fuel filter according to my wrench, due to the higher pressures CIS runs.....they physically look the same, and fit, but have a slightly different maker's number.

Same pump/part number on both cars although the PIAB has a secondary pump. The filter is different. It comes up a 924 part in US books.
Thanks for your input!

WEEKEND UPDATE:
Took the entire fuel system apart and cleaned everything. Finally pryed the fuel sending unit lock nut loose to check the strainer. There was a strainer alright, but it on the end of a metallic cylinder with 2 wires attached to it. I think i now know why the fuel is not flowing freely from the pick up hose to the (what I thought was the only) fuel pump. I think maybe that metallic cylinder with the 2 wires attached to it is somehow inhibiting the flow. Must get new metallic cylinder!
I'll be accepting this weekend's "dumb *** award".
I read Louie's tread about doing away with the intank pump. It sounds as though these pumps, or at least the hose that connects them, are trouble.
The PIAB has all the parts to convert to 2 external pumps. Any thoughts, pro or con?

Yep, very common cause of delivery problems, the"Pump Thats Not worth the Cost and Effort", or at least the crappy hose that fails mostly.

David,
The in tank pumps were provided on the earlier cars if they were destined for hot climates. This was to keep from vapor locking when sitting in stop and go traffic. IMHO it is overkill. If your external pump puts out 5 bar you shouldn't need the in tank pump or another external pump.

Dennis,
Do you know if the strainer assembly from the same MY will fit in place of the intank fuel pump? If it will I believe I will install it and check system pressure with one pump.
Thanks
