Facet Fuel Pump Replacement

[Kenneth K]

I'm putting in a new Facet Gold cylindrical fuel pump. The old pump used these brass compression fittings to mate with the installed copper fuel lines.



Do I need to buy new compression fittings (they will be mating with the same, original tubing I removed them from) or can I reuse these?

Also, do I install the fittings "dry," or use Permatex #3 sealant (or, other preferred sealant)?

Don't recall the product # offhand, but for all of our threaded fuel fittings I used a sealant specifically rated for diesel fuel.
(All of the factory 1988 fittings showed a little squeezed-out brown color stuff - sort of like a hardened waxy material, sort of - and zero leaks from any of those joints over the decades.)
Lucky for us that these sealants are used throughout industries far n wide, and should be well formulated, and readily available.

Added: just checked my Amazon order record and it was :
Loctite 483631 592 Thread Sealant

O34 - New Location: Racor & Lift Pump

As a part of the engine replacement project, we decided to move the Racor and electric lift pump out of the engine bay/compartment. Current ABYC "rules" seem to demand a metal bowl under the clear filter bowl, and this seems to defeat its purpose...

Permatex 80631, if I remember correctly. a blue tube.

Use Permatex #2.

Ken,
Do you have a picture and/or part number for the pump you chose? I've been thinking about a new electric pump but haven't pulled the trigger. I haven't gotten too excited about the real cheap pumps. But even with a Facet (or one with a similar price), I will have to do quite a bit of re-work to install one. They just don't make them like they used to. The fuel pump is the bottom unit, gold-ish colored.

Thanks,
Craig

Avoid the really cheap plastic cube pumps from auto supply stores, but I've had good success with a solid metal fuel pump that was ordered for a chevy pick up truck but never picked up. It has the correct pumping pressure, simple mechanism and designed for a truck, so was solid and was less expensive than marine. Has worked great for six years and going strong.

Craig,

I don't have my notes with me, but here is a previous post about fuel pump options:

Electric Fuel Pump

Does anyone know the specification for the original electric lift-pump that Ericson pared with the Universal M25XP engine? (GPH and pressure)? Our boat is a 1985 E-32. I think that the original pump was made by Facet but I've lost track of its characteristics. The pump has been replaced...

I think the Facet 476459E is the one I bought.

From the look of your existing pump, the Facet "cube" pumps might be an easier fit, and I believe they were highly recommended by MaineSail.

I haven't done fuel line work before, but most of my searches on thread sealants strongly recommend against using Teflon tape in diesel fuel lines (as is shown in your existing installation). Once you disassemble, shards/strings of that tape will be left inside the female threaded fittings and could present a clogging problem down the road--something to consider or seek further opinions on.

Thanks Frank and Ken. I'll look that pump up and see what I can find on non-marine pumps for diesel per Frank's recommendation.

I am planning to re-work my fuel feed system this spring, so that Teflon tape will go away. It is so tight in there that I am going to have to be patient once I decide what pump and filter to install.

The Facet cylindrical pumps have a filter on the bottom that needs to be changed periodically. You need to able to get a large wrench on the bottom to change it. Might be a no-go in a tight location.

+1 on NO teflon pipe-tape. I spent a bunch of hours last Summer chasing down an rough-at-high-throttle issue on a 60HP outboard. Finally traced it down to teflon tape on the fuel filter inlet folding over and choking flow.
