Note that will not work on the Passats because they don't have the 2nd pump in the engine bay
I.D. or O.D.?58K. I know that its probably premature/unnecessary to be doing this, and quite honestly, having come from the 1.8T gasser, I tend to look for things to do with this TDI. I appreciate your concern and knowledge sincerely.
In any event, it is done. I set it up with feed line (with $2 inline filter) and return of 5/16 vinyl tubing connected with brass connectors to the stock fuel lines pulled off of the fuel filter housing, and a foot of fuel hose looped back around connecting the open fuel canister ports so I didn't have to pull any fuses to the pump. I also primed the feed tubing with the DP with a small kitchen funnel prior to connecting to minimize any air space. Everything went very smoothly. Didn't notice any change in engine noise, and it took about 30 mins to suck up the DP (which smells like diesel) with a few occasional revs. I let it go until there was about half a cup left in the receptacle and then I reconnected everything and poured what was left in the gas tank.
After, engine started right up, and I drove around for 20 min to check it out. I can't quantify anything, and I wasn't having any problems before, but the engine does seem to rev up faster than before. Could be placebo in part, but it seems smoother. Anyway, if I'm the first CR here to attempt this, all I can say is that in my experience, the procedure went as smooth as I could have hoped, and I'll do it again. Your experience may vary.
Some members here (without VCDS) fill the canister instead of priming and it doesn't seem to cause any immediate problems. It is not the recommended method and nobody really knows if it might do any long term damage. However, I see absolutely no possible issues with filling the canister before priming. It probably can't hurt as long as DP is sufficiently lubricious.I will be performing Fuel Filter change on my 2010 Golf and was planning to fill canister with DP. That’s what I have always done on my ALH. I know it's recommended to prime system but has anyone filled canister prior to priming?
