Re: Fuel lifting pump making noise when first starting engine
 
A "Facet" brand lift was standard on thousands of Universal diesel engines, and there are very similar brands on the market. They all work the way yours does, and pull fuel thru the Racor and push it on to the engine spin-on filter and thence to the injection pump. Usually about 3.5 to 5. psi. Matter of fact, our former Universal M25XP would run without that pump on warm days.

When first powered up the clicking is faster and then slows down a lot when the pump comes up to pressure.

After replacing our old power train with a new Betamarine (which uses a mechanical lift pump) I kept the little 12 volt cylindrical 'Facet' pump in the fuel system to help pull fuel thru the new Recor after an element change, just like before.

If changing pumps, do some research, as a few of the Walbro pump models have had reported early failures.

Two completely different mentalities; sadly, we don't have a NAPA store out there on the briny. lol

Spent several years as the lead tech on an IMSA team. Also decided to see what Alaska was like as engineer on a fishing boat. Taught me a thing or two about spares. I can build a second car with the parts I have for my daily driver.

kriss-
Speaking of fuel lines and bleeding, if your fuel system uses copper crush washers, make sure to pick up a box (dozen) of them. They are used just once and thrown away, so if you find out you've got to bleed the engine, and then bleed it again because it wasn't quite right...you can wind up needing several washers for one incident, and the exact size you need is always out of stock.
If that's old news to you, "Nevermind".
