Default Any tips for priming a replaced Racor filter/fuel water separator?

Any tips for priming a replaced Racor filter/fuel water separator?

Ok here is my dilemma, my boat is at my dock.
The previous owner installed the filter in a tight spot under a hatch
and you have to turn it on it's side and then reach back up and in to fasten it
(don't ask me why, makes no sense because you cant see the bowl from there without a flash light and draining it is a hassle).
So filling it up with fuel before installing does not/wont work,been there tried that.
The prime bulb is installed at the motor after the filter
and by disconnecting the bulb from the motor side and
pumping it numerous by squeezing then putting my thumb over(prolly more like a thousand) times it still wont prime.
Installing a prime bulb before the pump is not gonna work unless I pulled out the console to get to the hose where I would be able to work on it.
I just want to get the boat out of the water,without having to buy an external tank
or go through the hassle of just disconnecting the filter and installing a
new longer fuel line,which is pretty hard to get to also because I would have to remove the console also.

So what I'm wondering is there any other simple tricks to priming these things?

Why did you disconnect the line from the motor side? It would seem to me that if you left it connected and just squeezed the bulb it would eventually pull enough fuel to fill the filter.

I would move the location of the Racor so that you don't have to go through this twice a year every year going forward.

My bulb is after the filter and I have never had an issue priming the system. You also sound as if its one with the clear bowl and they are not rated to be mounted below deck.

Because, it wouldn't prime while it was still connected...

See video below at 7 minutes 54 seconds.

Yeah, that wouldn't surprise me lol.
The guy that had this thing before me wasn't the brightest when it came to boats.

I may try reversing the bulb and then siphoning gas into the system backwards and see if that works.
then reverse the bulb and give it a shot.
I'm kinda stumped... LOL

I suggest installing a new primer bulb before the filter.

Here is another idea. Make certain the drain on the bowl is closed, not open. If open, it will never prime. It always seems backward to me and I have gotten caught in this before. Also, hook back up to engine to vent air on the + pressure side of the bulb.
Good luck.

Usually the engine fuel system retains enough fuel to run for several minutes on internal fuel. Start the motor, If it funs dry then the fuel bowl is not seated correctly or your drain valve is open..if I remember its backwards from normal righty/tighty. If all that is good then the engine fuel pump will pull more than enough to reprime the bowl.

You can move your primer to before the RACOR to prime it easier.

Please post where you find that. I've never seen RACOR/Parker say that except on inboards. I don't want to be at fault if I have a fire on board.

http://www.parker.com/literature/Rac...30R_Series.pdf


and

The Racor 320R-RAC can be used for either inboard or outboard gas applications with flow rates up to 60 GPH.
White powder coated to prevent corrosion
Three 14 - 18 ports; two inlets and one outlet
Use on vacuum side of fuel or transfer pump
Height: 9.38
320R-RAC-01: clear see-thru plastic bowl for outboard applications only
320R-RAC-02: UL listed metal bowl for inboard and outboard applications
60 GPH


OR

"See-Thru bowls can only be mounted below deck with Outboard Applications. If See-thru bowl is used with an I/O or inboard, the filter must be mounted above deck for USCG approval. Metal bowls can be used for inboard or outboard applications above or below decks."

check your anti siphon valve...it could be sticking making it difficult to prime..$10..also a clear bowl is OK when used with an outboard engine...no clear bowls when used with inboard engines due to it being a source of heat/spark.

Absolutely, positively not true in the case of outboard powered boats.
