Help translating two lines of Zhang Shaolin's "Hakka homesickness" (客家乡情) + some weird pronunciations in that song Song video. Lyrics, romanization (based on what I hear in the video), translation attempt.

张少林的“客家乡情”（客家话）

爱记乡情 齐家都係客人
最緊有煞拼求進 (AX 建议的写法) 
莫忘乡情 齐家係自家人
只只回故乡寻根
叔公叔婆来相认
亲戚送礼来好热心
到处都有人亲
做事耐苦
人乌白也分明
好硬頚客家人
客人最亲
亲情最真
世界客人 团结纪念乡情 (on ket nyi hiam hiong chin?)
血脉浓于水承认
事业有成 客家奋斗精神
晓出头自有原因

* 封做官(fon?)来人尊敬
救苦救清贫好热心
莫问自家出身
见面自家人
有个三分情
无忘本客家人

*

客家老人尊敬…

I must remember [my] homesickness   all [my] family is Hakka
[And] lately we have struggled for continued success 
Do not forget homesickness    all [my] family ar self-made people 
Each of us will go back to our homeland to look for our origins
[And] get to know great-uncles and great-aunts
[Our] relatives give us gifts [and] are very warm-hearted 
[We] haverelatives everywhere 
[We] work [and] endure pain 
And understand whether people are black or white (i.e. good or bad) 
Hajka people are very hard-necked
Hakka people are the most intimate 
Intimate feelings are the truest
Hakka people in the world    are united in remembering homesickness 
血脉浓于水承认 (?)
They have careers and success    Hakka struggles are energetic
They can succeed for they have a reason

* The honor of being magistrates is bestowed [on them] and people respect [them] 
They help the poor and help the needing and are very warm-hearted
Don't ask them about their own family background
I see the great feelings
That self-made people have
[And] don't forget [I'm] originally a Hakka person 

*

Respect old Hakka people... 

Questions:


Line 2 makes no sense to me unless I accept the spelling proposed by Ånton Xiè (AX), which I gave a translation for; is there a way to make sense of the captions, or do I just accept AX's respelling?
Even AX can't understand the untranslated line: what does it mean? We have "Blood dense in water confess", does that mean they acknowledge a great impurity of their Hakka blood due to mixing with non-Hakkas?
团结纪念乡情 should be "thon-ket ki-nyam hiong-chin", but I hear "on ket nyi hiam" at the start; what's up with that?
At the start of part 2,官should be kwon, but I hear fon; what's up with that?
Hakka speaker from mainland China here. 


there is karaoke lyrics on the video, L2 is 追根由石壁求证 which is correct. Not exactly sure how to translate 求证 here. Maybe: ancestry seeking is proven by the stone walls.
Your own translation is good. "Hakka people in the world are united in remembering homesickness / [And] acknowledging [their] blood is thicker than water." The uncommon order of words is intended for a better rhyme in the song.
团结纪念乡情 (thon ket nyi hiam hiong chin) I hear that's exactly what the singer is pronouncing.
官 is indeed kwon, but still I don't have any problem with the singer's pronunciation.
