Hi there JamesThe P/N shown on the perkins parts catalog is NA900087.The pump itself did not have legible markings, described asRotor pump (inner 4 rotors, outer 5 rotors)Pressure 2.1 to 4.2 kgf/cm2Shaft OD 15.82 mm No other information
I seem to have completed one purchase order via ezone-saint lucia. Waiting for confirmationI am now running engine charging batteries, after oil change & additive mixed, & results are identical to previous.Runs at 1200 rpm at 1,8 barsIdle at 700 at 1,2 bars This is after 4 hours running non stop (water temp 70°)No Volvo for me yet, will go back sailing & keep on runing old faithful.

Christian Alby,

   Do you know the exact P/N for the original oil pump in your Perkins engine?   
   Ebay shows that the pump listed by tacomadiesel 1969 was sold Jan. 24th at 10:41 AM for $60 USD.

Hi there James,
Pump shown on ebay from tacomadiesel 1969 is similar to previous pumps P/N 41314114.Worth a try if not sold already.I am still trying the Prevalent supply via www.getezone-saint lucia; new to the game there I am still chasing them to know if transaction is valid or missing some hidden step.Will let you knowFair windsChristian alby - Desirade VIII - Maramu 116 - le Marin Martinique

Christian Alby,

  This link should show you the details and a photo of the oil pump that sold yesterday on Ebay:  https://www.ebay.com/itm/Perkins-Oil-Pump-/162047206348?epid=1666806067&hash=item25bac423cc%3Ag%3AERQAAOSwPc9W1hX7&nma=true&si=W3eCbTcEMLa7SbrtDwkjy5OzDVc%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557  If this link does not work let me know.  Please let me know if the photo looks like the correct pump to you.  The seller had a 100% rating so I believe that this was a valid transaction and a lucky find, sorry that we missed it.
   I have not heard anything back from Prevalent from my email inquiries and my attempt to purchase the two pumps.  Checking into the website, though the company checks out through Google transparency,  I think that it is very unlikely that they have any actual pumps in stock ever.   If I hear back otherwise I will attempt to complete the purchase for two pumps.   I will set up an alert on Ebay in case any additional used or new pumps show up.  It would be helpful if you can help insure that the part #41314114 is indeed the correct pump if at all possible.  
Best,

Christian Alby,

   I just saw your email.  The pump on Ebay has been sold,  bad timing there.  I have placed an order for two pumps thru Prevalent but have not yet received a confirmation either in my browser or via email so not sure yet of what is wrong.   No need to pay for my pump, but thank you for that.  I just hope that this company actually has stock and that these are the correct pumps for our engines.    I will update you when I have more information.

hi there James
tried the eBay code but Zero results reply .... losttried purchase from Prévalent-first but cannot complete registration ...tried to purchase via getezone site ... no reply yet
As I do not want to lose one of those pumps I would ask you to purchase both & sell back one to me, I will pay for both - bank transfer to your account - and arrange with you for shipment of one to me in Martinique. Soon as mounted I will confirm if OK & then you can reimburse the one you chose.
Your help is really appreciated there

Christian Alby,

   Can you verify if the correct Perkins part number for the oil pump you need is #41314114?  If so then I may have found two sources for new surplus oil pumps.    One is located on the website at: https://www.prevalent-first.top/perkins-4-154-oil-pump-41314114-cf-bedford-marine-engine-p-5822.html.  I am thinking ordering one for myself as a spare if this information looks correct to you..  
The other pump is located on Ebay, item #162047206348.  The Ebay ad shows part #41314114 and says that this pump fits the 4.154. 
Fingers crossed that this helps..  I also have some inquiries in for a used pump.  
Best,

Christian Alby,

   I have been keeping my eye out for a replacement pump for you but so far no luck..  I think that you are correct that the worn pump is at least part of what is causing the lower than normal oil pressure.  The sudden drop of oil pressure to 0 when you reach 2000 RPM is very strange and I have been pondering a possible cause.  It makes me think that somehow the pump gear has sopped stopped turning.    Did you notice if any of the gears on your oil pump are pinned to the shaft?  I have seen some oil pumps secured with pins but am not sure about the Perkins 4..154, hence this is just an educated guess.  If one of these pins were to shear from the engine runaway and lack of lubrication which you said occurred when the engine failed,  you might still have enough friction present to drive the pump gear at low engine speeds but it could then begin to slip.  Replacement of that pin (if it exists) might solve the problem with the sudden loss of oil pressure.   Please let me know if you someday figure out what is the actual cause of this sudden loss of oil pressure.   I will post here if I am able to find another pump.   Can you tell me from your research if the non-marine version of the 4-154 has the same oil pump as your engine?

I still might give up on replacement here in martinique & keep on looking for an oil pump to do repairs, then sail to better deal location.

Hi there Christian
As a fellow maramu owner with an older engine I’d be interested in your thoughts about the Volvo D2/55 as a replacement vs other alternatives.. 
Size, simplicity, cost etc? What led you to choose the Volvo?
Many thanks and best wishes

Christian,
I am afraid I have no good ideas that match your symptoms!  Since you have both the gauge and alarm reporting low pressure, I have to assume it is real and not a problem with the measurement.
Sometimes low oil level can cause low pressure at high rpm as the pump sucks so much oil out of the crankcase it sucks air, but you checked that.
A stuck open pressure relief valve that resets itself when the engine shuts down could be an an issue, but that seems unlikely.
Maybe someone else has an idea or two...  in any event do let us know what the solution turns out to be!

Losing oil pressure at high RPM and having it come back at low RPM is a bit of a puzzle to me.  There are ways it can happen, but they are a bit exotic

Do you have an oil pressure gauge AND an low oil pressure alarm?  If so, is the gauge showing low pressure AND you get an alarm?  Does the oil pressure drop quickly at 2000RPM or does it drift down slowly?  Is it stable, or does it bounce around?Does it come back quickly when you reduce the RPM, or does it stay low?
