This is a very difficult to get item to get! Many have said soaking the existing one in kerosene for a few days will do the trick, have not done that yet as I am still trying to track down a new one. Wondering what the success rate has been with soaking it in kerosene, also wondering would WD 40 do the same thing. Would hate to ruin the one I have, which is original to the car!

I don't know the L-Jet system...but Bruce says above that L-Jet does not have a decel valve. I Google "Bosch 022133551" I see "Decel Valve 1.7 1.8 914" and "914-4/1,7. 914-1,8/2,0."
http://www.autoatlanta.com/Porsche-022133551-srch.html https://www.porscheatlantaperimeterparts.co.../022133551.html Anders states, "1970 -1971 1.7L 914's didn't have a decel valve, because their ECU cut off the fuel flow on overrun." https://members.rennlist.com/pbanders/DJetParts.htm So does L-Jet have one? Looks like it's the same for all engines. I found it interesting that some listings described it as a "Vacuum Limiter Valve". And I guess that's true, in a circuitous sort of way; by bypassing the throttle plate to add intake air, you are increasing manifold pressure/"limiting vacuum"... Ian, I suggest asking the tech to test your decel valve as I described above. I'll rummage my parts stash tonight for a spare and if the tech finds yours is not properly functioning then let me know. |
