This morning set up a small test system using air, interesting results.

Set air pressure control manifold from shop system to 55 psi then tested gauge used on Fastback, identical within a few tenths, did the same at higher and lower pressures, gauge is good. Then plumbed the gauge into a tee/hose assembly with one end attached to air pressure supply at 55 psi, the other end to the FPR/ opened valve, adjusted the FPR to 28 psi at gauge, no problems. I then looked up pressure generated by E2000 pump, specs suggest 80-95 psi. Increased air pressure from manifold to 95 psi opened valve and the FPR could not handle the pressure, i.e. could not adjust to 28 psi. Tried this on both the original FPR and the new FPR from Bus Depot, neither could take the simulated pressure of the pump. I dropped the supply pressure back down in increments and finally around 60 psi was able to adjust pressure at FPR to 28.
Erm, sorry, I only suggested air pressure to test the calibration of your gauges, under static pressure. But using air pressure and flow to test the operation of the FPR is a quite different dynamic scenario. I wouldn't expect a regulator designed to work with an incompressible liquid with a given viscosity to work with a compressible gas. Completely different animal.

But glad you were able to get to the root of the problem, Good on ya.

Good point with regards to the characteristics of fuel vs. compressed air. My main goal of the setup was to prove accuracy of the gauges but while I was there wanted to see if the FPR was adjustable, this setup accomplished both which led me back to reviewing the entire fuel system setup, locating the self inflicted injury/problem.

Waiting for parts for the exhaust had to shop multiple vendors to get everything, hopefully I'll get years and years out of these pieces as they seem to be getting scarce.

Thanks for the valuable input and Happy Holidays!

Happy Holidays!

Installed NOS muffler and heater components yesterday after finally finding everything I needed, engine sounds great when first started (one turn of the key, YES!) unfortunately once it is warmed up still have the wandering of idle followed by an eventual stall. Immediately restarts which I find interesting. I will continue to educate myself on the Djet system to address the symptoms as they occur. At least with this issue it won't be self inflicted, hopefully.

Starting to like this little car a little more each day. Progress on rust repair continues.

Please test the manifold sensor with your very own mouth applied vacuum. See if it holds. Not too much, just enough to see if it holds. Let us know ...

Already completed that task, it held vacuum, the next question is how long is it supposed to hold? I have another that came in a box of parts, holds mouth created vacuum as well, same part number as the one currently installed. Maybe a quick switcharoo would be worth the investment in time to see if it makes a difference? I did take the manifold sensor apart to drain oil as it was dripping out of a small hole when I first cleaned the outside of it.

That was my first question, actually.
Apply vacuum then hold it under vacuum with your tongue. It should hold your tongue to the edge for ten seconds.

The manifold sensor on car held strong for 25-30 seconds then started to lose some suction. My backup barely made it to 20 secs. total, not much of a backup, although may work in a pinch. After putting hose back on from manifold rechecked both connections to ensure they were tight as well, new hose, all is good.

You have a backup? This is one of the few cases where I would swap in a spare sooner rather than later. They're not hard to connect AND they're pricey. Even if the spare holds vacuum for 10 seconds, it would be enough to narrow down your list of suspects.

I will do this as soon as I am back in NY. Enjoying the FL climate currently. The car came with a box of parts which included MPS, fuel pump, coil, and a bunch of other items that I will use as I continue to bring this car back to life. I am still amazed that I can go out to the garage turn the key and he/she (yet to decide) always starts, similar to my 66, 6 volt beetle.

Have now finished almost all the rust repair on the passenger side of the car. Front bumper mount, front fender crash box, entire rocker/heater channel and rear under seat. The drivers side front bumper mount and crash box have also been repaired. Next is drivers side rocker/heater channel replacement then on to the rear issues.

In between have also cleaned up the floors and weld repaired the battery area.

I have pictures but need to convert and downsize the format to post. Maybe tonight.

The drivers side is complete, minor patches in a few places to go. Pictures hopefully this afternoon.

C'mon its only been three weeks... Since its snowing outside I will work on today. Note reducing the size/format of the photos so they'll fit website rules is a time consuming task ... like everything else with VWs.

The good news is both heater channels are in, both front fenders are weld repaired. Next will be working on full paint removal and prepping for paint. This front end, including fenders, were seriously mangled/rusted through, more obvious whens some of the paint and filler are removed. Three to four weld patches per fender with a bunch of hammer and dolly work. Also of interest was that I was able to use a razor blade and scrape the outer red paint to the original deep sea green, unfortunately not enough of the factory left to save.

I'll post a bunch of pictures later today.

Ok, finally have files converted to a format that works for IAC. Please remember that my skill level with patching and welding is limited as this is the first time that I have done "body work" to this extent, certainly the first time welding to such an extent. While I have learned plenty since jumping into this Fastback, fuel injection just one example, my education will continue as I plan to complete all of the bodywork myself; sanding to metal, filler, along with primers and topcoats. This way I will have on one to bitch about by myself.

Start the photos with the inner fenders which were complete disasters, especially the crumple zone boxes and bumper mounts, oh and everything underneath them.

Note that the pictures posted in reverse order, you'll figure it out.
