OBS fuel priming tips and tricks

I just went through a hell of a time getting my powerstroke to start after replacing the orings and hoses on my fuel bowl. These things truley are a bear to get started after replacing fuelbowls/pumps etc. At the end of the day I figured there has to be a better way to prime the fuel system besides pouring deisel in the bowl and riding the starter all day.

So for future referance what are some of the tricks you guys are doing to help alleviate some of the cranking time on a powerstroke?

Can press the schrader valve by the FPR while you crank it over to blow SOME air out but basically there is no way to better prime the system. Crank 'er till she fires.

...having said that, don't burn your starter. Crank stop wait.

I remember back in the day when I had a 6.2 detriot I used to pressurize the fuel tank with an air compressor and some rags and that would push fuel up to the filter. I might give this a shot next time I have to service any fuel components.

In all the years I've been working on mine (plenty of fuel pumps, bowl removals/rebuilds), I've never had to bleed or prime the system. They have always started like I never cracked open the system. One tip: don't forget to close the drain valve! It makes a huge mess, especially when the engine starts. Cheers!

I guess I am not so lucky to have a truck that fires so easily after fuel system work.

Anyway, I had to pull my fuel bowl off again to replace a leaky drain valve and I figured out a system that works best for me. So if you ever run out of fuel and are stranded on the side of the road and dont have anyone to help you might want to try this method out before running your batteries down cranking the motor over.

1.) fill the fuel bowl approx 1/2 to the top with diesel fuel and reinstall the fuel filter.

2.) get a small screwdriver or any pointed object that you can use to open the schrader valve. unplug the top of the starter relay and hook up a small piece of wire to the top terminal.

3.) simultaneously touch the wire to the positive side of the battery while bleeding the schrader valve (do not put the key on run). I spin the starter over 5 seconds at a time giving the starter time to cool in between runs. Do this until fuel starts to come out of the schrader valve.

4.) hook you starter relay back up and your truck should start on the first attempt
