Thought I'd transfer over to a new thread, my last post from "Changed hoses and it still doesn't run right":
"OK, after doing a lot of soul searching, and like I said, not being in love with this car, I made the hard decision to keep it and try to fix my problems with the hot weather running. Problem is it hasnít been hot enough out lately to replicate my problem described above. Car has been running just dandy, though. Iíve been on the NeoBentley a lot lately (thanks tons tolusina ) and came across the picture of the CIS fuel pump taken apart with around 150,000 miles on it here: http://forums.vwvortex.com/zerothread?id=2890716
Whatís really telling is just how much that armature is worn out. I just have to believe that mine is in the same condition. The weeniemoble has around 180,000 miles on it. So I was going to order the whole fuel pump works from GermanAutoParts.com but decided to run this by the local FLAPS I trust so much called Cost Less Auto Parts in North Vancouver. They quoted me a rebuilt main one, a Python brand, which they say theyíve had very good luck with for $108 and a new transfer in-tank pump for $54. Short story, I went and picked them up yesterday and will get to the transfer pump tonight and the main pump this weekend. Will take tons of picís and post up the results, but I probably wonít know if this solves my problem unless the weather gets above 90F again, and it doesnít get that hot all that often around here.
Let's start the new thread [IMG]http://*****************.com/smile/emthup.gif[/IMG] :
Well, it turned warm again this afternoon and when I got off of work, I pulled out into traffic and promptly got into stop and go for 10 minutes before I could get to the freeway on ramp (Which usually takes me 1-2 minutes). I finally accelerated onto the highway and got up to speed where the car promptly shuddered and shook for a few beats, but then settled down and ran nice up to North Vancouver. [IMG]http://*****************.com/smile/emthdown.gif[/IMG] Ah yes, the hot running car blues, again. Thoughts of selling the weeniemoble flood my mind at that moment, but I have the new pumps at home. If I can just get home.
I was dreading getting off the freeway back into stop and go traffic, and it did hiccup a few times on the surface streets. I pulled into a gas station (Got gas for under $4/gal for the first time in months! [IMG]http://*****************.com/smile/emthup.gif[/IMG] ) and put a couple bucks in because I was low, and this enabled the car to sit for a while, and I hoped at least let me make it a few more blocks. I got to the Boys and Girls club and picked my daughter up with no further problems, and turned and headed for home, not knowing what to expect. Easing it off the line and in shifting, seemed to help. It only hiccupped once on the way home, (shifting from second to third up a hill) and when I pulled into the driveway and shut it off, there was no way I was going to drive it again without at least changing the transfer pump in the tank.
Changing the in-tank fuel pump is a snap. Nothing to it at all Iíll take you through mine.
1. Undo the two screws in the front of the back seat bottom.
2. Pull the seat out and Voila! Look at all that treasure.
3. Clean all the dirt and debris up. Youíre only interested in the round black cover on the passenger side. Take the three screws off.
4. The cover comes off to reveal something like this
Mine has been messed with sometime in itís life because it has a screw hose clamp on the top hose (non-standard) and a crimp type (standard OEM) on the bottom hose.
5. Undo the hose clamps .
6. Take all the hoses and electrical connector off the top.
7. Now see those notches around the outside of the top of the assembly? Get a big screwdriver and hammer and whack it counter-clock wise. For some reason, mine took a real good whack to unlock. It will only turn about Ĺ inch, so be careful.
8. Now comes the fun part of finaggleing that whole assembly out of the hole. It doesnít seem like it will come out in one piece, but hereís proof it does. (after a good 2 minutes of twisting and turning)
9. Well, at least my screen on the bottom of the old pump wasnít clogged with Ka-Ka (good thing) Kinda old looking though, and when I peered into the tank, you could clearly see the bottom through the gas and it was in terrific shape, no rust or sediemnt at all. Iím very happy.
10. Take a good pair of dykes and cut off the OEM clamp from that little piece of hose that goes from the pump, to the top assembly
11. Hereís what it looks like apart. Just leave the old hose on the old pump, you donít need it anyway. You did get a new piece of 5/16" hose didn't ya?
12. Ah, my new 5/16 fuel line and new screw clamps. I got 2 feet, way overkill.
13. Put the new pump on the top assembly, just like the old one. Connect up the electrical connection. I just cut a chunk of new 5/16 hose the same length as the old.
14. Clamp it down good and snug.
Finaggle that pump and assembly back into the hole and make sure not to pinch the o-ring under the top. Whack it back into place with the screwdriver in the notch, this time going clockwise. It only goes a little ways and locks into place. Mine really snapped into place smartly. Tighten the clamps on the hoses and reconnect the electrical connector.
15. Thatís it, folks!!
16. Ah yes, an excursion under the back seat can potentially make you somewhat wealthier if you had the right previous owner, but alas, all I got was 11 cents, a cool little tin of Tiger Balm, and a previous owners Blood donor information cards and Oregon Liquor Control Commission I.D. card from 1981. And a very suggestive little piece of wood, almost like a cork. HummmmmmÖÖ..
Does the weeniemoble run better? Like I said before, I have to wait for hot weather (Maybe tomorrow afternoon?) to find out, but it did fire right off and revved like a VW should and settled down to a real smooth idle, something it hasnít done in a long time. Next on the list is the main pump. Iíll post picís of that change, too.
