There were TWO original fuel pump push rods that I have ever seen during my yrs. Early ones were the LONGER length and the later on for the offset Alt clearance were shorter...have both in my tool box to inter change when needed.
Problem that I saw was the angle Alt fuel pumps were not equal as for the length of the rod needed and depending on source of Mfg it would vary.
Part number the same but what rod to use was the question.
If the car were here I would blow air back into the tank first cleaning the metal line and gas should flow out clean. With that done clean fuel should be going thru the filter into the fuel pump. Any air bubbles after that would be a sign of a fuel pump issue (hose connection or the pump itself) maybe the rod length?
Other things to check but I would need a quick visual inspection....some things a person would think are okay but in actuality questionable.
Sold a NEW 34-3 over the counter one time and always gave a NEW filter.
Guy comes back (with his ANGRY wife in tow) and the car would NOT Idle.
When this happens with any Carb 1'st thing I do is back off the Idle Jet 1/4 of a turn. In this case removed the jet and there was a small bit of straw looking piece sticking in the small offrice of the Jet. The factory does not supply those. When I asked him why the NEW filter was NOT used he thought the old one was okay. Cleaned out the jet...new filter and they drove away.
Anyone see my points and reasoning> |

Just wanted to report back that after HRVW suggested checking the incoming fuel line I cleared it out the old fashioned way. That is with a deep breath. Now she is running as good as ever. Just love it when it is something simple! Just a bit too coincidental that it happened after timing her properly.
I have a little time tomorrow to tune up the Kaddies a little better and hopefully I can stay fweeming for a while.
Thanks for the help... again! Especially HRVW |

Aaargh, my problem returns. Is it time to drain the tank and clean it out? _________________ 71' Super 1600 DP Dual Kadrons Stage 3 Cam...

We have a process of elimination to take care of pronto.
Pull the coil wire to the dist....get a small can....remove hose from the fuel pump outlet and crank over the engine. Gas should squirt out strong into the can. Gurlgling would mean issue is the Fuel pump or the rod and your running lean for the Carbs as a result with it NOT feeding the Duals.
Your mention of a different looking rod caught my eye as there is only a Long (early) and a short for (later) pumps.
Like I mentioned on some post at one time the offset (alt) would use either the early or late rod depending on the MFG.
I saw those pumps at my VW parts house yrs ago.
Visual inspection inside the tank for any rust at the bottom near the "sock" will also help for a diagnosis. That might be the repairable solution with a NEW "sock" part # 111-209-021G (complete unit is best) |

I will recheck that fuel pump. I can't remember what the exact length of the pushrod was but it was not either of the two listed sizes.
I hope it isn't that sock been dreading that. _________________ 71' Super 1600 DP Dual Kadrons Stage 3 Cam...

Use a hose and siphon out most of the gas into a Gas container.
Pinch off the hose underneath to the tank. I should be about 6-8 inchs long attached to the metal line. (small vice grips will work.
Four bolts hold the tank in place......remove them and then lift up and out where you can remove the old drain unit and install the new unit...breeze.
Then reinstall with NEW hose and clamps holding the hose in place.
Many say to put a filter here and as a VW expert of over 28 yrs a 100% NO.
Having a leak there with a 1/2 to maybe a full tank and a filter leaking your going to have a lot of gas going down your arms to your arm pit and it BURNS.....been there and done it many moons ago on my own and customers cars. |

I too have had that wonderful experience, don't forget the Eau De Petrol cologne you wear for a few days too. Maybe I can rustle up a fuel tap somewhere to add if I get this far.... _________________ 71' Super 1600 DP Dual Kadrons Stage 3 Cam...

I checked out my fuel pump and it is getting good flow from the tank. As the starter is turning over i am getting "spits" of fuel from the pump and a constant gravity trickle of fuel.
Also when I was checking spark pulling off each wire from the dist. #4 seemed to bog her down the most. Spark plugs are pretty fresh (500 miles), should I check there? I only ask because it is a pita with the DP Kaddies. _________________ 71' Super 1600 DP Dual Kadrons Stage 3 Cam...

Would not hurt to have a filter before the fuel pump and one after the pump narrowing down any tank debris.
The pump should put out a good squirt cranking over or engine running.
Exchange #4 and #3 wires to narrow down the wires themselves on those two cyls. If the drop in the engine stays the same that will weliminate the spk plug wires there.
Double check the valve adjustment on both #3 and #4.
If the problem still exists then you are going to have to pull the $4 spk plug and replace with another.
I have three sets of used spk plugs (very LOW miles) when trying to narrow down a problem with my 1776 Turbo and after a lengthy hassle found that my 20 yr old Elect Ignition was slowly starting to take a dump. My electrical miss etc problem was obvious so NEVER throw old spk plugs away if the electrode still looks okay inside and NOT burnt...they come in handy at times.
The #4 spk plug will show if the cyl is WET with oil or gas or maybe not firing due to the plug itself or a VAC leak with the manifold. |

I have new filters before and after, both look clean.
I think its a pretty good squirt that my pump puts out. I will try and post a video of it.
I will check those wires.
Valves were just checked adjusters were cleaned up.
Sigh, you're probably right i should check those plugs.
The other day I was adjusting my accel pumps and noticed a drip out of both of them so I turned the pump down until it stopped.... That should only be affecting when they are triggered though right? _________________ 71' Super 1600 DP Dual Kadrons Stage 3 Cam...

Tell you what...I think you have the WRONG fuel pump push rod that was cut down by somebody that should NOT have done that.
Just checked thru my stuff and I've the CORRECT GERMAN short and long push rods. I would exchange them on a customers engine depending on what fuel pump they had bought from another parts place other then myself. just a courtesy on my part and a public relations thing.
Will not be crossing into San Diego until the 3rd so give me your address via a PM and I will send you one of each to try out. One that is NOT needed you can send back and keep the function one as a Christmas present.
That sound okay? |

Awfully nice of you HRVW, I would hate to trouble you. My local VW parts counter knows me well and they should have both rods.
Would the wrong size pushrod make the pump work so erratic? I have put 1,000 miles with hardly any fueling issues besides this. _________________ 71' Super 1600 DP Dual Kadrons Stage 3 Cam...

:)Good morning. Doubt you will find any rods from your parts guy unless he has access to some used parts. The rods were never a replaceable item since they never wore out like pistons, bearings etc.
My collection came from acquiring cores from a wrecking yard.
You have until Dec 2nd to let me know if you want me to send the correct rods. No sweat on my end. |

Removed pushrod and it seems to be a mm or so short.
But i did discover my problem... It's a weird one, my main jet for the #1-2 side had ejected itself...? It was just sitting on the butterfly, luckily. _________________ 71' Super 1600 DP Dual Kadrons Stage 3 Cam...
