Not upset at all, it's your car, do as you like, but be warned it's not as simple as some let on to swap if you want it to work properly.
Test fuel pressure before changing the pump.
Points or Pertronix?, new plug wires?, old tested ones?, ever done a smoke test?

Posting this as Im needing info on a 1979 VW SuperBeetle Convertible, California Car , fuel injection
.
Problem is i need a new muffler and was wondering what if any are my options .
Really don’t want to change heater boxes or modify the exhaust .
Will a regular fuel injection muffler for the same year car fit,
They sell one for Canadian fuel injected cars ( non cat )
This would eliminate the cat and short muffler.
Will this other type of muffler fit my car ,
Without changing the heater boxes ?
Thanks for looking |

AFAIK yes, the non Cal muffler fits in the same space the California Cat and muff does, since you don't have to smog delete the cat.

Samba classifieds are the best spot, what's wrong with your's?, unless you broke off the adjustment stud, or the element is fried they are not hard to get working properly.

Is there a base setting for the air flow meter adjustment screw ?
I don’t have anyway to test the CO levels. |

Not really, you could try the carb method for no meter, adjust for peak rpm and then lean until revs drop by 50, should be close enough until you can get near a sniffer.
Lean is CCW on that one.

Thanks
My original problem with this car was an issue with the idle … went through eveything and then i found the airflow meter adjustment- lean ccw and rich cw
I turned it in ccw and the car is now sounding like a VW and i have lost the rough running .
Also found out more on the backstory of this car and the possible reasons for all this - disgruntled shop owner , setting up for the car being stored for a year on his lot .
I think some screws and valves were changed & adjusted to make the car not run .
Thx Mark for the help again |

| 1975 VW Bug Fuel Injection Wiring Help. So A really good friend of mine is helping to get my original Car back on the road. And we cannot find where the RED and Black wire that connects to the starter to supply power to the FI relay is, It was there several weeks ago but now we cannot find it and have been looking all over the under side. Does it come from the engine side to the starter or the body side? |

Red and white as stock - goes from starter to the double relay inside the car, behind the back seat and attached to the ECU IIRC. The red and black goes up to the ignition switch. I don't recall how it routes. Is it missing from the starter solenoid?

The 79 diagram is all fubar on the connector numbers and locations things like "T8g" on the diagram but the numbers on the key don't go highr than 3, odd.
The 76/77 diagram shows the red/black for the double relay splitting out of the T1b single connector under the back seat (other branch to the starter #50), then going to T6 which is a 6 wire plug in the engine compartment, and finally to the DR.
The 79 is drawn exactly the same there, but the key or plug numbers are screwed up somehow.

Hey all thanks for the help, but still need to know where the wire comes from to try and trace it. Just spent over an hour under the car remove wheels to find this wire and still nothing. Any help would be greatly appricated. |
In my car, behind the seat on the right I have my ECU and a dual relay. There are two connectors plugged into the relay. One all white which is for the FI loom and the other which is the engine loom. The red black wire should be seen here. Do you have this? The engine loom then finds it was forward, along the front inside of the seat base - then loops back down under the heater pipe. There it merges with the thick red/black cable from, I think, the ignition switch. Both red/black wires connect to a red wire from the left (driver side) seat base through to the engine bay and I assume the starter solenoid terminal.
Double Relay
Under seat past the battery
Along the seat base
Connecting to the red wire towards the starter solenoid

I've got a 76 that I need to connect the heater hoses to the heater boxes, through the engine tin. (I think they are called heater hoses.)
When clamping to the heater box, there's not much space. Found the connection pipe listed, but can't confirm it's going to fit. (Jbugs year compatibility is frequently wrong.)
Not sure why there's 2 different kinds.
Anybody order these from somewhere?
Here are the links.
Thanks in advance.

Those don't fit anything made after 1974.
The fresh air tubes have intermediate pipes between the rear tin and the heat exchangers on FI cars. There's usually a few in the classifieds, except for right now...., there is one pair included in this complete system pictured below, they are at 11:00 in the pic, one is super squiggly and the one below is shaped like ~.

If you don't need a full system try asking some of the wreckers like Avery's, or the others listed here: https://www.thesamba.com/vw/shops/cat.php?id=12

Thanks. I had no idea those existed. Are they made of metal? I'm guessing so.
I can see how that would make the connection easier than stuffing a long hose through the tin like it is currently. |

Can anyone confirm this accelerator cable tube fits my 76?
https://www2.cip1.com/vwc-113-721-551/
I found this from another member back in 2015.
Although the standard beetle isn't specifically listed, I assume it's included.

The pipes are made of metal, like I said it's odd there's none in the classifieds right now, maybe try Awesomepowdercoat? If you can't find anything maybe some of that bendy flexible exhaust pipe might work.
As for the tube the 113721551 should fit, super and standard are only different ahead of the front door posts after 75.
