What is this guys ? is it a sensor ?
The top one is a check valve for a vacuum line, most commonly the brake booster.
for the vacuum controls for vents in the car
Thanks ! It was the original short fat rubber pipe and clamp still on there.
Connecting to a electrode thing that goes into the car

Yeah, that's not an electrode thing - it's simply a rubber reducer with a small steel elbow that connects to a thin vacuum hose that goes into the cabin to provide vacuum for the airflow flapper valves (the 3 buttons in the centre console that you push to get the air to come out the top, face level or foot level). The thin rubber hose is connected to a vacuum tank behind the radio in the centre console. The one-way valve (black and white thing) prevents all the vacuum from escaping when you accelerate. It may appear to some of us a "silly question" but we have to remember not everyone on here is technically-minded or has a lot of experience with any particular car, so happy to help - keep the questions coming! :)
thanks very much that is very helpful . The hose that connects to the engine and the one-way valve is about 10mm long, it was original and very thick. Where do you find your rubber hoses and where would i find the one -way valve ? . I had started pulling of hoses looking for any leaks as i had an issues coming home about a 30min trip from town but it took me about and 1 1/2 hrs to get home . First in town i had lose of power and stayed like that for awhile but then deteriorated on my way home . I would lose power and stall in the middle of the road, after awhile of turning it back on after a 5min rest i could putt up the road until it would stall again, eventually i had learned that i had to have a 10min rest pull out the spark plug and put it back in and then start it up get driving and once i got to 80kh without the lose of power i would then have to keep the acceleration pedal in the same position at 80kh either going up the hill or down otherwise the car would quickly lose power. It was great to get home as i thought i was going to be getting a tow truck but the trusty tank got home putting all the way except the hairy 80kh part which was nerve as its a rural road with lots of twists and turns. I checked fuel relay and looks original it was wrapped in insulation and another sticky brown tape. I still havent found the issue but first im going to replace the hoses and then check out the carburettor, fuel relay and anything you guys mention, i dont have a good idea about what was going on really but it would be great what you guys thought, thanks again
Is this a car you've recently purchased or one you've had for a while and it's just started having troubles? It appears to be a K-jet 240 (what year?) If it's been sitting without being used, there are a number of potential issues, such as poor/old fuel, gummed up fuel distributor, gummed up fuel injectors, clogged fuel filter, rust in fuel tank, that could cause it to be low on power and stop running then re-start after it sits for a while...especially rust in fuel tank that blocks the filter "sock" in the tank as when you shut the car off, the rust can disperse away from the in-tank filter over time, then when you start driving again the rust gets sucked back to the filter and it blocks up again causing the car to starve for fuel.
I'm not sure why pulling the spark plugs out would do anything?? Unless it's running extremely rich and the plugs are getting wet with fuel? What do the spark plugs look like? Are they black and sooty, wet, oily, dry and white? That could help diagnosis.
You should be able to purchase the vacuum & fuel hose from any auto parts store or even Clark Rubber. Just take the old piece in and get them to give you the same size. Is the one-way (check valve) bad? You should be able to blow air through if you blow on the white side, but no air should blow through if you blow on the black side.
I don't recall the fuel pump relay being wrapped in the black goop (maybe the wiper delay relay?) I guess the fuel pump relay may have a layer of white or yellow foam wrapped around it that is stuck on by a thin brown double-sided tape. Just make sure what you think is the fuel pump relay is indeed the fuel pump relay. Usually the car would die totally if the pump relay overheats or is bad...it wouldn't just run slowly. Another possible problem would be you're not getting enough fuel due to a failing in-tank or main fuel pump.
Hope that helps - hard to know what's wrong without knowing more about the car and its history.

Ahh yes I see that now. I had no end of grief on that 79 244DL with the single SU carby so I'm not very well qualified to answer LOL. Carby version has no fuel pump relay and no in tank fuel filter sock...so those are ruled out. Could still have a blocked fuel filter. Could also be stuck float causing over fuelling and flooding.
- Edited
I bought it in 2016, sold it in 2018, then the other day i called the guy if he still had the volvo and said his grand daughter has it and drives it to work she put 15000km on it. So i made him a offer and he took the offer . Its a 240 DL 1981 . It has been maintained in fair condition, it has not been driven a real lot.
Yeah ok, No goop just insulation and tape on what i think is the fuel relay, I found it behind the wall in front of the passengers feet spot .
Clark rubber thats great ! thanks for the rubber info.
the one-way valve seems fine. But just have to get a new rubber as i had to splice it of and damaged the clip
Sorry not the spark plugs but the distributor leads
Worth checking the points in the distributor
can you clean distributor points , the hard plastic seal that is between distributor cap and distributor was cracked on the edge and frail ... should i just get new distributor cap, ignition leads and spark plugs.
You can clean and reset the points but probably best to replace.
I would also check that there's oil in the carburettor damper, as your issue was throttle related.

It does have an in-tank sock, it is a cylindrical thing, part # 1211175

Ahh, I had seen a pic of the carby fuel sender unit and it looked like it just had a steel tube at the bottom to pick up the fuel. I guess the filter was not present.
