That's the best video I seen which I already know how it works can work on Volkswagens for over 40 years but that's good for some people that don't understand
Thanks. We're trying to come up with more ways to educate on how your old VW works and how you might be able to keep mechanical repair costs down. If you got any suggestions, please feel free to let us know and we'll do our best to accommodate
LOVE my rebuildable fuel pumps I own. The price point of selling a QUALITY pump, that we'd make ourselves, would drive VW owners to installing a GOOD electric pump and a decent regulator for laterally half of the price (and I'm not talking about a crappy pump & reg......YOU know the brands I speak of here). So what's the answer for the entire VW owner-dom, here?
Any chance you could do a video showing what gas going thru filter should look like, mine looks like a fountain goi g off in there, then after throttling it always cuts out and dies
Try fuel pump rod carcraftstore.com/fuelpumprod.aspx And make sure you're checking VW parts stores. I don't think you'll find it at any other auto parts store. Good luck
W/O seeing it, my answer here is in NO WAY definitive but MOST will be stamped w/ an arrow but USUALLY the top one is the inlet. As a cautionary piece, if you can't decide which is which, don't mess w/ it and have a professional mechanic install it
I’m getting too much fuel pressure with both types on my car. (6psi with generator type and 5psi with alternator type. I only need 2/3 for my little formula vee engine. Do u have any idea why it’s producing too much pressure? Iv never had this issue before. Great video thanks
I do. It all boils down to quality control, or a lack of. Unfortunately, our little FUEL PUMP, the FUEL PUMP RODs, the PUMP BASE it sits on and the thickness of the "gear" that the rod travels up and down on (thats 4 items that need to be within a HAIR to create the correct pressure) are just not up to the quality/specs they once were. Good news is, you have options! OPTION ONE; get a fuel pressure regulator. Not a cheapo. Get one that actually will go on a race car and pays particular attention to the under 10lb mark. OPTION 2; You need to take off/grind a millimeter or 2 (in some cases maybe 3) from the flat end off the "fuel pump rod". OPTION 3; add another fuel pump gasket (or 3 in my case) to the base of your fuel pump.
In case you didn't quite get exactly what I was saying.....the rod is plunging to deep into the pump, so we're either raising the pump, OR we're shortening the rod. And BTW......(here comes your unwanted advice!) w/o going in TOO deep here ( no pun intended!!), the closer to 2 psi, the better. 2.4 is on the high end if you actually calculate out the factory specs, then convert FROM metric. Remember, these cars were all done in metric by people WAY more particular then you and I. Good luck and I hope that helped
To reduce pressure you add more gaskets to the base of the pump, each gasket drops 0 3 bar I think, so you need to use a good bunch of them. I would probably try and make my own from some heavy duty cardboard instead but it's your call.
I have a 73 sports mobile camper it has dual carbs I got fuel in it but won’t fire over but it turns and tries to start I’m thinking the fuel pump any tips to fix and also adjust carbs is appreciated
Neil, not enough info to make a pin point response BUT check to see if it's getting fuel. IF it is, start looking at the distributor. If it's not, go to the pump, young jedi. Good luck and keep us posted
Question , if you use the generator push rod on a alternator pump. Will that lead to excessive fuel pressure going into the carburetor and fuel mixing with engine oil ?
Sorry for the delayed reply, Big John. Spring time and VW outings are hand in hand!🌞🌊🌊 It will contribute to this. "Yes" to the entering into the crankcase. That combo could mean a near future engine rebuild. No bueno, amigo.
That's for an earlier, smaller motor. I've currently got one on an 1835,w/ duel Kads. After accommodating for its fuel flow, it works great and has that cool old school look I wanted airheadparts.com/vw-part/fuel-pump-repair-rebuild-111-198-555/ They have a tech department that will help you and is second to none, but have patience, they field call from ALL over the world
They're SUPPOSE to pump no more then 2 psi (2.2 psi is starting to be on the high side) BUT, due to the LACK of quality control nowadays (it is what it is!), I've tested brand new ones, right off the shipping container at 7 psi! WAY to high to ever get the motor dialed in w/ stock components. This will contribute (to a certain degree) to most flat spots on the beloved 009 distributor (which I personally don't use)
My pump fuel pretty much trickles the fuel into the fuel filter, is this normal? The motor only fires up and runs for a few minutes after l use quick start through the air filter.
So sorry for the late reply. It's old Volkswagen season around here and thats a busy time for me. Depends on what your idea of a trickle is. The pump should only be pumping 2 psi (2.2 to 2.4 to be exact) even with duel carbs.
THERE IS MORE THEN ONE WAY TO DO THIS, BUT......For ME, its a 2 person job. I disconnect the main coil wire (the one the same diameter as the spark plug wires), AT THE COIL. Doing this will allow someone to turn the engine over, w/o any chance of it starting. NOW I can disconnect the fuel line AT THE CARB and place it into an empty clear glass vessel. Have the person in the car turn it over. About 5 to 10 seconds is all you'll need to see if fuel is coming into your glass/jar. Be careful of the fan/alt belt, it still can "grab' onto sleeves, long hair etc. If your glass was good and clean you can put the fuel back into your tank, or just dispose of the fuel properly
ALSO a VW air cooled engine insists on around 2 to 3.2 pounds of pressure to operate (Fuel injection VW's are excluded, here) the car properly, this ENCLUDES MOST DUEL CARB SET UPS. This equates to not much more then a dribble and why your air cooled VW operates just fine w/o an electric fuel pump and pressure regulator......I mean, unless you enjoy wasting your hard earned money.
I have a Generator type. It ran fine last year now it won’t pump fuel. I have changed the fuel pump and rod and it still won’t pump fuel. What could it be. Thanks Appreciated
you can do a "search" on the world wide web as to your year, make & model for your cars codes. Even if you can't fix it yourself, you'll at least have an idea of what it is. WARNING; Some codes are VERY generic and won't tell you exactly what is wrong BUT will give you a system. Example; "fuel supply" Good luck and hope that helps
Me again. I’m sorry, I don’t no how often you check your sight. But I’m kinda in a pickle. You see I am a clown in the Shrine unit and our first parade isTuesday. Sure could use an answer quickly. Thank You
