When I was driving my '85 GSL home today, I noticed that it was significantly low on power, especially above about 4000 RPMs. I though it might be a slipping clutch, but when I stop and rev in neutral, it does the same thing. I've made NO changes or modification to my car since it started doing this this afternoon. The only thing I can think of is a dying fuel pump that isn't delivering as much fuel as it used to.

Any ideas??

 

Sounds like a pump or filter.

 

I agree with Hades, I just went through this, it was the fuel pump. When I checked it, it looked good, but when I replaced it, it fixed the problem.

how much is a fuel pump, ive felt a little lagging in my GS latey too. The clutch should be in good shape, feels like it................

 

Where do I buy a new fuel pump? I checked at Checkers and Advance Auto Parts and both of their "OEM replacements" were over $100. I thought the stock 12a pump could be had for like $40.

 

Holley red for $75ish

Mallory if you like quiet

 

advance auto has a universal fuel pump for carb. that pumps 4-7psi and i've had one on my 82gsl with no problems and had one on my 83 gsl with no problems

it's 32$ and is with the fuel filters

 

Did you have any problems mounting it or wiring it with the $32 universal pump?
