And because it's not needed factory fuel system works great on a superduty. Just rebuild the fuel bowl every 10-15 years and be done with it. Works great until you start getting into 180cc+ injectors.

Agree to disagree on that point, based on annual bowl rebuilds with high priced dealership parts. I pass on the factory bowl. You'll have to pry the Bosch 040 fuel pump and Aeromotive bypass regulator from my cold dead fingers. But that's me, you do you.

Fuel bowl rebuild kit from diesel o rings is $25. I did it once about 10 years ago and did it again about a month or 2 ago when I had the bowl off doing something else just as preventative maintenance. Never had a leaks since the first time I resealed it and I don't really consider $25 every 10 years to be high priced. I'm not sure why you think it needs annual rebuilds. lol

The fuel line compression fitting seal kit was $35 or $45, bought that once. The fuel bowl drain valve was I want to say $75 but could have been more, bought 2 of those in as many years. These were local dealership prices, but when you need it you need it. The second drain valve was the tipping point for me. That was when I decided that over priced dumb s**t had to go.

I’m not really wanting to get in the middle of this, but these parts are cheap enough to keep a set on hand. The fuel drain valve rebuild kit with the better Orings is less than $7. The full bowl kit including the Parker sleeves for the lines is $21. 🤷‍♂️

Like you said, you do you, but the logic on this one is eluding me.

You can get complete seal kit from diesel o ring for $25. Thst comes with all the o rings, all the fuel line compression seals. New upgraded o rings for drain valve and o rings for the wif and heater assembly. I'm still running the 25 years old original drain valve just replaced the o rings in it with ones in that kit. Couple months ago when I rebuilt it again as pm all the o rings still were soft and pliable and were not leaking anywhere after 10 years.

I'm not arguing the fact the parts are available from Diesel O Rings cheaper than what I paid. Only stating what prompted me to find another way and that I feel that other way is better suited for my truck. Hence the "agree to disagree".

I think I’m just going to drop the tank and check out the pump and its components. Hopefully it’s just dirty screens, a leak, or even just in need of a whole new pump. I really don’t want to think about hpop problems. Although now that I think about it, I did notice a ticking sound that to me just sounds like an exhaust leak coming from under the hood not long before the priming issue started. It’s hard to tell because my ears are shot, but would any hpop problems result in a noise like that?

Have you checked the stand pipe valve? Friend's truck had almost the exact same issue, and that was the culprit. Easy fix

I pulled the stand pipe out and checked it out. The spring came out of the bottom easily but I had to take a screwdriver to pop the inner piece out of the outer piece of the actual stand. I figured that must be the problem and put just the outer piece back in the fuel bowl to make sure. So it’s been running without that check valve assembly and nothing changed. I thought briefly that was the problem but I guess not.

Then I turned the key over to the on position for a couple seconds like I was needing the glow plugs and it started just like normal. I had to do that the rest of the day. When I got home I changed out the fuel filter (which had less than 1k miles on it) with a new one (oem) thinking maybe a fuel issue? That solved the problem for one day and now it’s back to needing to be turned on for a couple seconds first or it will just sit there and crank, no start. It’s not a big inconvenience but I imagine it’s a sign of something wearing out and needing replaced? Also it’s summer here in Oregon so I’m pretty sure it isn’t a fuel temp/glow plug issue. Any ideas would be much appreciated. Thanks
I decided to go back to refresh my memory(getting old is a bi*ch) on what the symptoms are and what we've done so far and this struck a cord. Just last week I was having some trouble with my Toyota FJ behaving just like this. I recently installed an external fuel filter because Toyota thought it was a good idea to put the original one in the tank and make it non serviceable. GENIUS! Anyway, after installing the new filter setup I would intermittently get a crank no start, but turn the key off then back on again and it would start. Long story shortish, I had introduced a boat load of air into the fuel line and it was causing the trouble. After 3-4 times of burping air out and spraying fuel everywhere it's since gone back to normal.

Air in fuel can cause ticking. If I’m remembering your stuff correctly, I think you’re dealing with a leak on the suction side, plugged screens, or both (plugged screens will make suction side leak worse).

Did you ever pump fuel out the drain valve and see if it’s clear or foamy?

I’d check that then drop the tank. The H&H mods are good to have anyhow.

Basically yes it's a little easier if you happen to have a couple feet of 5/16 or 3/8 hose handy. You can slide the factory tube off and put your hose on. Then just open the valve, point the hose in a clear bottle or safe direction, and cycle the key for a couple seconds. You should immediately have clean fuel with no bubbles or foam coming in the jug. If not then you got a leak.

I checked the fuel coming out of the bowl and it wasn’t foamy at all. Looked pretty clean. But I went ahead and dropped the tank anyway and cleaned out the screens. The pickup one at the base of the pump was very clean and the two tubed screens inside the pump housing weren’t that bad. I did notice one of the breather lines coming off the end of the tank was corroded and broken so I replaced that. It seems (maybe it’s all in my head) that it has a little more pep but nothing changed as far as needing to prime the system or it will just crank without fire. So I’m starting to think this isn’t a fuel issue. I will add that this whole thing started once the weather started to warm up. Could it be an hpop issue with my oil (delo 15w-40 with about 1k on it) being too thin or something? Starting to run out of things to check on the fuel end. Thanks
