Buy the vacuum gauge that fits on top of the fuel filter from Racor. It takes the place of the tee shaped fitting.

Rick:

RE the bulb, as Nick said, put it between the tank and the Racor. Use whatever size bulb that fits the fuel hose; there are several sizes of bulb fittings so measure the ID of your fuel hose before buying bulb. Also, prudent owners put a standard hose clamp on the line instead of the squeeze on clamps that come with the bulb, just for added safety.

RE the gauge, if memory and logic serve, it will go on the other side of the Racor, between the pump and the Racor. I...

The bulb goes between the tank and the Racor. The filters can foul which would be indicated by the vacuum gauge. If the fuel pickup tube in the tank gets plugged you would feel it in the squeeze bulb. It would not "rebound" after you squeezed it.

For the primer bulb and vacuum gauge, where do you recommend inserting? Just after the tank, after the racor? what size (in Hg) gauge? just curious.

I want second Nick RE the squeeze bulb in the fuel line. After installing one, I have never had to bleed lines again and don't have to mess with diesel which I always manage to spill.

I also recommend putting a vacuum gage in line to measure how much the primary filter is clogged. This gives ample warning before a filter is clogged and allows you to replace it BEFORE it kills your engine some dark night. This is very cheap insurance.

Just FWIW...

I added an outboard motor type squeeze bulb in the line between the tank and primary filter. After changing the filters, pump the bulb until you hear fuel run back into the tank. The engine starts right up.

Restarting after filter change is SO much easier if you prefill the filters with diesel BEFORE you put them back on. Otherwise it is easy.

Make sure you turn off the fuel supply before you open the Racor. There is a petcock on top of the fuel tank. This is a good time to check that all of the clamps are tight.

I usually drain the transparent bowl and wipe it out. The new filter has all of the gaskets etc.

Thanks for the input all. Does anyone have a quick run down on the procedure for changing the Racor filter? I hope to get down this weekend and give it a shot.

David,

Those are the classic signs of a clogged fuel filter. It's probably time to change out both filters.

I second Gerry's clogged fuel filter diagnosis - when running at slower RPMs enough fuel can get thru. However, powering up tries to suck more fuel thru the filter, and the pressure compacts what were once "openings"...

We once had a clean filter but it was the wrong filter and it caused problems. Yard installed a 2 micron instead of 30 micron.

We enjoyed a great sail down to Crisfield, MD on Saturday, a nice broad reach all the way down from Solomons Island. So of course, there was no wind yesterday for our return requiring us to use the iron jenny.

About a mid-way in to the trip, the engine started to fade like I had pulled the throttle back but then it came back to my orginal power setting. Twenty minutes later, did it again and then kept it up the whole way back. When I pulled the throttle back, it ran steady at the...
