Hi, I live in New Mexico and am having the same issue with my 66 Beetle. If
you find a solution, I’d love to hear about it and I will do the same for
you. Thanks.
I need help removing my 71 Super Beetle’s steering box! Please help, I
can’t seem to be able to disconect the box from the upper link to the
steering wheel! It’s some sort of universal pivoting joint and I have no
idea how to take that out!
Mine still runs fine its just harder to crank after its hot same problem?
I want to try this, my local VW old timers say it has a slim chance of
working, seems like a viable solution to me,, why would they say this???? I
am in New Mexico and it ovee 100 degrees now, I think I am gonna switch to
an electric pump, ant thoughts on that…
Hey chris, i thought this was my problem! ended up taking the pump off and
the guide bottomed on my block with no effort. My experience with my 1600cc
single port engine was it would start up fine when cold, with a little
drive and parking it, would not start upon return. i do live in arizona -_-
Have any suggestions?
First try pouring water over the fuel pump.Believe it or not this actually
works! Im in Roswell NM and we average around 112-120 degrees each year
every day, and each year my thing vapor locks. I just pour H2o on the fuel
pump and thing fires right up and were on our way. I always have a bottle
of H2o ready…Give it a try you’ll see.
What do you do if the stem gets stuck? I can’t get mine out, it seems like
it is swollen and it is made of that plastic brown bakelight material. I am
a bit concerned about breaking it and having pieces of it go through the
engine I have a 74 super beetle. cheers.
Long live the Mighty VW Beetle !!! Thanks.
I need help. I got a new fuel pump and the rod that goes with it but it
dose not pump the fuel
WOW, is your tank vented properly? Correct gas cap? Are you in a hot
climate? How full is your tank?
Great tip!
Hi. Having the same problem with my ’72. Did you fix yours? What was it?
Cheers,
In Germany we prevent Vapor lock with adding 1% API TC two stroke oil to
the fuel that has a great anti boiling additive that pervents fuel vapor
lock try it…in Germany and VW and Porsche vintage driver does so
Hey Chris. Great little how to video. I checked my pump stand out and sure
enough the rod was sticking and the stand had a lot of friction. Ground it
down. Running great. Thanks!
Another method is to drill out the bakelite passage so the rod has space.

Well that’s deff. Not vapor lock.. Vapor lock is when a fuel line is to get
hot and boil the fuel in the line….. that is a sticky fuel pump Rod….
Good vids tho
there are two rod sizes available for the beetle. One is short and one is
long. You have to buy the correct fuel pump for the correct size rod. Its
possible that you had a short rod, and bought a new fuel pump that needs
the long rod. That’s probably why its not pumping cause the short rod can’t
reach to pump lever. Either take it back and get the right fuel pump or
find the correct rod. Sometimes I have taken the lever of the both pumps
apart and swapped the levers.
Thanks Chris!!!
I was on the side of the road for 4 hours today because the little pin that
the arm in the fuel pump pivots on came out. Not to mention one of my plug
wires were bad.
PERFECT!!! My 1974 Thing had this and your fix was exactly right!
I have a 68 beetle and I am having the exact same problem. I’ve become a
fuel soaked maniac trying to get this thing fixed. I’ve replaced the fuel
filter, all soft fuel lines, fuel pump, done several tune-ups which helped
a bit, checked for vacuum leaks, and still have the issue. When
disconnected the soft line from the tank the fuel came pouring out so I
don’t believe it’s clogged there. When I shut off the car after driving a
while I notice bubbles in the filter coming from the pump side.
I was driving my 56 Oval back to Kansas from Rhode Island in July of ’89
and had this problem but I can tell you it wasn’t from a sticking pump rod
because as soon as the sun went down the car ran great! But thanks for the
tip I appreciate it.
Hey Chris, I was looking at my beetle the other day and noticed the gas cap
had some gas leaking. So I decided to open my gas cap. When I did this it
shot out gas like a garden hose. What could be this problem. I didn’t get
much help from thesamba on this topic.
How can I check the venting on a super beetle with the gas expansion
chamber. Gas cap looks normal from what I see for sale online. I am in a
some what hot climate, around 80-90 max. Often it is 75 or so. Sometimes my
tank is only about 3/4 full, and it will still do it.
Chris, I did do this to the fuel pump stand however the engine was not at
running temp. Do you think I should Re-Preform this measure after its
warmed up??? Still having problems. She starts perfect after sitting for a
few days however after driving it I hold the throttle all the way down to
get her to start Puffs a little white smoke at re-start, Then it seems she
runs only on 2 or 3 CYL. after starting then smoothes out within 15sec or
so…. HMMMM??/ Can You Help?
good info thanks,
You are My Hero…..
Also it is so extremely important to make sure the rubber seal around the
engine shroud is in good shape and fitted correctly. That way all the hot
air is being pushed out and not recirculated back in the engine
compartment. Great video.
Have you tried the clothes pins on the fuel line trick? It acts like a heat
sink and wicks away the heat from the fuel line.
How about the numbers for Lotto???
my 1972 vw superbeetle is having a problem. when i press the accelrator the
engine seems to sputter. fuel filter does’nt seem to filling up all the way
like it use to. replaced fuel filter with clear fuel filter. it(the filter)
has not gotten dirty again after replacing it. I replaced the “cloth” fuel
line that joins the incoming metal fuel line and fuel filter. any ideas ?
take fuel pump apart ? also u mention put some type of grease in the fuel
pump, where at ? what type of grease ?
Ok I will look into venting. Thank you.
Sounds like venting, you have to make sure all of your vent hoses are
hooked up and not blocked off.
Thanks for sharing!!!
i had the same problem but my pump stand was stuck in the engine and i had
to pry it out/up. i would hate to know how many people have replaced there
fuel pump thanking it was bad because of this problem.
