Can anyone confirm what year (or better yet, month/year) the dual fuel pump set up was changed to a single in-tank fuel pump? I have an 88 SETA (build date of 10/87) and I keep getting conflicting information.
My issue: On my way home from work on Tuesday I noticed a buzzing noise coming from the rear of my car, only audible when the windows were down. I had heard that the main pump in a dual pump setup will buzz to compensate for a failed in-tank pump. The noise I hear is coming from the right (passanger) side.
Yesterday morning I turned my car on and again I heard the buzz on the right hand side. Unfortunately, I also noticed a fuel leak under the engine so I left the car at home.
Later that day I replaced both fuel lines coming from the rear up to the H adaptor. Car did not making any buzzing noises last night when testing for a fuel leak. Fuel leak is now gone. When I was tracing the fuel lines from the tank and filter to the front I noticed that only the filter was there but didnt think to check anywhere else for a second pump. Where exactly would the pump be if it were a two pump set up?
I start the car up this morning and again no noise. I am about 10 minutes from work and I can hear the buzz again. During this whole time where the buzz is happening I am not getting any kind of weird idle. There doesnt appear to be a change in power (its an auto so I use that word lightly) so Im a bit confused on what could be the problem.
If I need to order a replacement pump I would need to know if I need a low-pressure in-tank or high-pressure in-tank. Any way to tell besides having to get under the car...at work?
I would REALLY appreciate an answer quickly. Thanks.
