No start after parked uphill

I am going to guess this is a fuel filter head issue or just air in the lines building up over time. Last week I had my CRD parked on a +/- 35* hill overnight. In the morning it wouldn't start. I cranked it for 10 seconds 3 times. Initially i thought the diesel gelled up since it dropped below 30* overnight and the station didn't switch over to winter blend. I went to the fuel filter head and pumped the primer a few times and it fired right up. I parked my car in the same position on Friday and Saturday morning was the same exact situation. Last night i parked in the same spot but faced down hill and in the morning there was no issue. I'm guessing there is air in the filter head that needs to be bled out and when I'm in the uphill position, the air pocket is sitting by the outlet to the fuel pump. This is all just a complete guess. I do not have a lift pump and since getting the Hot tune, I have thrown a "fuel leak" cel a few times at WOT - This is really just an air pocket hitting the pump and throwing it into limp mode until cleared.

Sounds like you are on the right track as air would tend to "pool" at the high point. Pump the primer until it gets hard then crack the bleeder screw (I like to stick a piece of clear vinyl tubing on the bleeder screw and run it to a catch bottle to keep the mess down and so I can see things); if you get a lot of air then close the bleeder (snug not godzilla) and repeat until no air. Do you have the 1st or 2n gen fuel head; see Sir Sam's NOOB guide fuel head bleeding video for the difference. If 1s gen best replace if 2n gen and air problem continues add lift pump (see my comments at viewtopic.php?f=5&t=72091&p=757412#p757412)

Of course if this doesn't solve your problem update your past and we will go from there.

I've not had fuel gelling problems on regular diesel down as low as around 20F

I wouldn't expect standard petro #2 to gel above 10 degrees F. That is the traditional "you gotta do something" temperature.

I'd bet money on a leak in the fuel head. Other than when the original battery died, the only time mine ever failed to start was when it was parked nose up and I had a leak at the heater.

The fuel filter worked its way lose. I was priming it and saw some bubbles coming from the rubber seal. Its all tightened up and no issues.
