Hello Everyone,

I am a new member and have a 1982 GS i saved from getting crushed. I'm having a few problems. My car runs great, starts every time and will go like hell for about an hour and then the engine starts choking. I think it may be a fuel filter because it's getting worse. The problem I'm having is that I don't know what I'm doing. I found what appears to be the fuel filter inside a guard attached to the underside of the car just in front of the rear axle on the driver's side. I purchased a replacement filter. Looks normal- cylinder with two straight pipes coming out. What i think is the filter looks to be a little larger with both pipes having a 90 degree bend. The casing is two pieces with flanges held together by two phillips head screws. It's also got two wires black/black w/ white going into the underside of the back of the car. There is also a cylinder hanging with two lines coming in on the top. I was under the impression that that was the carbon canister... I've been known to be wrong before. This seems like a stupid problem to have. I'm sure someone has changed one of these before. I appreciate any help, and thank you for your time.

 

If its got wires coming out of it, its not the fuel filter. go to FAQ and download a manual. It will help. The fuel filter should be next the fuel filter. I do have an 81 though.

 

Let me clarify
The item your describing is the fuel _PUMP_! (with wires, etc) - which is UNDER the cover, the filter is -if you are looking towards the REAR of the car, with the pump in FRONT of you, the fuel filter is BEHIND it - ie: between the pump and the rear wheel, completely _exposed_ no cover... Its held by a thin wire looped frame assy that it will just pop out of. THAT is what you want to change! And should do so YEARLY!

Thanks,

That's exactly what I needed to know. I thought what i had was the carbon canister. I'll get that changed. Thanks again.

 

7Aull is right. Filter and pump as he said. I have something similar to what you are describing as a choking engine. I replaced the filter and it didn't help. Next thing I am going to try is some sea foam in the tank. I am guessing that I have a restriction on a little mesh screen on the fuel feed line. I have also heard that the injectors could be clogged by some crap. The filter I took off was significantly clogged. I could hardly blow through it. I would say change the filter when you change the plugs. It's easy enough and on these older cars who knows whats in the tank. I will post again once I find out excactly what is ailing my 7. Good luck!

 

I must say that I'm a little bit illiterate when it comes to automotive chemicals, can you put sea foam in your gas tank? More importantly, Does it burn through with your gas?

 

Do a Google search on "sea foam motor treatment".

I've never tried the stuff, but a lot of forum members swear by it...
