Racor fuel filter problems

[Mr. Woof]

I have installed a Racor fuel/water separator on the frame of my truck. I plumbed the system in with new fuel line from the tank to the filter and from the filter to the fuel pump.

I cannot get the fuel system to fill the fuel bowl on the engine. I have run the pump 5 or 6 times until it shut off and still the fuel bowl is dry. I know that the fuel pump is moving at least air as when I open the fuel drain on the engine filter I can hear a puff of air.

I'm going to replumb using the original metal line.

What did I do wrong here? I even filled the Racor with fuel and still can't get the truck to start, I don't want to fry a starter solenoid.:confu sed:

Maybe the Racor has just enough flow restriction that the pump doesn't like it? This guy sorta leaned in that direction with a Frantz fuel filter, though I'm not sure why he thought the fuel pump was straining: Frantz Fuel Filter | Superdutypsd.com

You might disconnect the line just past the fuel pump, and at the fuel bowl on the engine, and blow air through it (including the Racor filter) with an air nozzle set to a lower pressure, to see if there is an obvious problem.

[Mr. Woof]

The Frantz filter uses basically toilet paper as the filtration media. I can see the fuel pump straining to suck through that. The Racor is a much courser media. I believe that I if I lightly pressurize the fuel tank, I can get the fuel pump to re-establish prime and fart all the air out of the new fuel lines.
