    I have an issue of fuel dripping from the front of the fuel pump, see first pic. Likely will this be solved by replacing the brass rings but i want to replace the pump since I have to take it out and its 29 years old.
    The original pump is Bosch 0580 254 947. The new one delivered by Eurospares is another Bosch 0580 464 125. Is this the correct one?

    thing that worries me most is the fact that the end of the threaded nose of the new pump is not closed like the original.

    Did anybody with 308QV, Mondial 3.2 or 328 install the same Bosch 0580 464 125.......and can confirm that its the right one.

    Change the accumulator while you are in there too!

    I replaced the accumulator few years ago already!

    I hope someone can tell me that the Bosch 0 580 464 125 is the right pump

    Looks like a 12v Bosch to me. It should generate the expected 4.7-5.4 BAR and min of 2.2 liters/min.

    Thanks Rob. yes, it delivers all of that. The main issue is that the threaded nose-outlet is open whilst the regular one in closed (also below the screw-cap).

    I just replaced in a 308. The fitting on the end is different and you will need different plumbing. I had a U shaped fitting and had to replace with a braided flex hose, but be careful as the bend is tight and you can easily break the vinyl interior hose in the flex hose.

    Is that not the anti-return valve that you take out of the old pump and transfer to the new one? Don't I recall that from my 328?

    I think your 308 had originally another pump than my 1988 328. The plumbing remains same for me.

    In the later 308QV and 328 I believe the later style pump has a screw-in replaceable check valve and the banjo fitting with hard fuel line to the accumulator.

    Please tell me when I am wrong but it seems that for my 328 I just put this new pump in place and refit the existing hard fule line with banjo and new brass seal rings. So the check valve is delivered with the new pump integrated with the hollow threaded pump outlet.

    I have replaced the fuel pump in my 1988 1/2 Mondial 3.2. It was BOSCH part # 69532. (Ferrari part # 121727). Hope this helps!

    Eurospares, Superformance and others now deliver Bosch part #65911 and name it Ferrari part #121727. The Bosch pump carries the number 0 580 464 125.
    Does anybody with a 328, 308QV or Mondial 3.2 install this pump............successfully.

    as the pics above sho does it seem that the pump did come with the check valve.

    Installed the pump today and it does do the job perfectly so absolutely the right pump for a 328

    No, I don't know why it's pictured in the Amazon page. I had to order the valve separate from the pump.

    Dear all, I can confirm that Bosch 0 580 464 125 is the right one and delivered complete with the check-valve in the outlet as shown in the 3rd pic of my initial post. I installed it and drove the car few times. Starting is great, runs immediately hot and cold.

    However this is the case for the 328, Mondial 3.2 and 308QV. These models have the Banjo fitting. The earlier 308 need in addition the convert the connection from pump to accumulator to accomodate the banjo fitting.

    After two years I try to update your info.

    Now, if you order a Ferrari part #121727, Superformance sends one unknown Sytec OTP019 fuel pump at the price of £103.10 (+VAT), when this pump is sold online at about £70.00.

    If I wish one compatible pump I go to buy directly online and I don't order to an official Ferrari parts dealer.

    After this experience I've bought one Bosch 0.580.254.947 directly online.

    From my research about this matter.

    Once upon a time there was the following original cross reference:
    Ferrari Bosch/US Bosch/EU
    #113976 #69523 0580.254.975
    #119291 #69609 0580.254.910
    #121727 #69532 0580.254.947
    #140317 #69535 0580.254.011
    #155592 #69410 0580.464.990.

    At an unknown time the parts #113976 and #119291 were superseded by the part #121727, i.e. the Bosch pump 0580.254.947.

    Eventually, at another unknown time, for the part #121727 the originally chosen BOSCH pump 0580.254.947 was substituted with the pump 0580.464.125, as you've mentioned in the initial post.

    But ... these two pumps are different for several reasons, as anyone can check from the technical sheets at the links
    https://emea.resource.bosch.com/AA/internet/enfinity/img/products/0580054001SI0000COB9MM.pdf (0580.254.947)
    https://emea.resource.bosch.com/AA/internet/enfinity/img/products/0580254013SI0000COB9MM.pdf (0580.464.125).

    I think I'm lucky enough to have found one 0580.254.947 to preserve the originality of my 1986 3.2 Mondial recently bought with only 36.444 km.

    The Sytec OTP019 pump is marketed as "alternative" to Bosch pump 0580.254.910 (i.e. the "old" Ferrari part #119291) and there is no whatever evidence that it is also "alternative" to Bosch pump 0580.254.947 (i.e. the Ferrari part #121727).

    p.s. I hope every reader will apologize my mistakes of English language.

    Thanks for the update. After more than 2 years I can inform that Bosch 0 580 464 125 is doing no less than an excellent job. This one was supplied to me by Eurospares at GBP 103.10 ex VAT using Ferrari part # 121727. These relative simple electrical parts are today better and more compact than back in 1988 and I am not surprised that various others can be used as well as long as the fit in the holder clamp.
