Car is studdering up top finally found two issues I’m not sure which it is. I vacuumed tested my FPR 10 mins at 10lbs zip tied everything loses a lb a minute. Also did a fuel pump change and got a faulty pump so I put the old one back it’s a walbro 255.  I worm clamped back together. I drive it get a good pull then nothing after that and the idle fuel pressure is 30 

I was doing a fuel pump swap thinking it was weak. I found a weird tail fitting on the outlet is that the cone filter everyone is talking about? It has a screw in the middle if it is can I eliminate it and cut the banjo end off and worm clamp it together

Hi everyone, I have a 1987 TSI turbo (125,000 mi.) that is blowing white smoke. I store it in the winter and this last spring when I started it, thick white smoke poured out of the exhaust. After a while it thinned out but even the next day it stilled smoked but much less so. The car has never done this before, even after storage. If it were condensate, I would think it would disappear after warming up. The antifreeze level has not dropped one bit. The exhaust does not smell of antifre

I'm mentally/principally having trouble pulling the trigger with MKS for $125 when 2 years ago they were $75 on the site and not too long before that they were $50 or less and somewhat available. I've checked and kept an eye out at the usual part stores but none have come available.
