  There is one in the fuel module and one on the fuel rail. When bought my 342 the one in the fuel module had the vacuum line for the impeller housing hooked to it.

  Yea, the pricing is just crazy. Probably a $3 part to make.

  So, if you were having possibly fuel related issues and you check your fuel rail pressure, you might think one of the two(?) Fuel pumps are bad but it could be one of the two fuel pressure regulators? Man! What prompted you to change yours aero?

  @rasbury , the vacuum tube on it was loose. I’m guessing the weld or epoxy broke.

  Does anyone know if you can cross reference these numbers on the regulator to a part number? I’m not 100% sure but I think the wrong regulator was installed on my port side module. The second pic is the new regulator that I believe is correct. The part number for the new regulator is 892681.

  Now I’m really confused. My starboard side regulator matches the one that came out on the port side.

  The new regulator is 43.511 PSI (300 kpa) the old one is 41.77 PSI (288 kpa). What one seems like the correct PSI regulator??

  @Alswagg , do you happen to know if Mercruiser changed the part number on the cool fuel regulator? Why would the new part number be almost a 2 psi (1.74 psi) difference?

  this says all ecm models 2002 and up, mine runs at 43 psi so 300kPa sounds right to me.

  So I guess if I’m replacing one 288 kpa with a 300 kpa on the port module, I should replace the regulator on the starboard module to match?

  I copied that out of a merc manual 
  Bet the other one is the 300kPa

  No, I checked the other day, it’s a 288 kpa.

  @Black_Diamond , On my 330 it’s pretty easy to access. I would think the same for most models.

  New regulator is in on port side. It was tough to get in, I had to use the bolts to draw it in even with lube on the o-rings. I should have the new starboard regulator sometime next week. The vacuum tube pulled right out on the old regulator, definitely would’ve caused some issues.

  Make sure that vacuum line goes up to the manifold and not the one for the raw water pump. That's the one that was on mine when I bought my boat.

  Forget what I said you have a different housing on your pump then I do.

  What were your symptoms for needing to change the regulator?  My engine doesn't like to start when it's warm, needs throttle to start if engine temp is warm/ hot. I changed the temp sensor and no change.  Hunting for cure here.  Thanks!

  @rinker270nb , the only reason I had to replace it was because the vacuum tube weld came loose.
