    As most of you know I had to replace my fuel pump and with issues removing and installing. but i got it done and car is running fine. The Deatcsh pump makes a crazy noise when turning key on. there is about a 1 second screech, Is this normal? I know that the Deatcsh pump has what as described as a turbine pump (are they all turbine pumps?) but it doesnt sound good. I know that many have complaints about after market pumps making loud noises.

    No not normal. My first guess is install error.

    Its a pretty straight forward install and it went back together fine, what kind of install error would cause it to make that noise?

    Is the new pump bigger than the old pump?

    Same physical size as oem pump, but many have said Deatsch is one of the best and puts out more pressure. The noise is kind of like a large zipper being zipped up real fast.

    Ok. I was thinking maybe it's longer so it wouldn't have as much clearance at the bottom to suck up fuel.

    Don't forget aftermarket pumps are generally louder. I remember I could hear my GT pumps prime when I turned the key. My current 450's are pretty noticable before the car is started.

    DW supplied the injectors (and I thought the pumps) on the current Cobra Jets and they seemed very knowledgeable at PRI, so I’d expect they are quality products.
    You said issues removing and installing in first post, so I’d first suspect something incorrect on the install. Have you called DW?
    Aftermarket high flow pumps are louder and you’ll notice the prime but not as the noise you’re describing.
    DW should have a few troubleshooting options.
    Good luck.

    My issues with removing and installing was mostly with the fuel line at the tank nipple, here is that thread https://www.svtperformance.com/threads/fuel-pump-stoped-working-i-think-car-wont-start.1194911/ The install of the pump was pretty straight forward with no issues---what would/could be incorrect with the install that would cause the noise??? The car is running well but the noise on initial key on is weird--------One theory that I have is that the pump/fuel system is leaking down and when turning key back on after car sitting the pump is re-priming.
