    Low fuel rail pressure with aux tank

    It was installed before I purchased. It look like main tank and aux are plumbed to the electric switch. I have not had any issues up to about 1 year ago when the issue happened after 40 gals used. Now it is just over half tank. No problem with main tank. Sent from my iPad using Tapatalk

    Should invest in replacing cracked head

    I also thought about the cost of new (used) truck. That is why I am getting it fixed. I am going to replace the Turbo as it will only cost me extra for part only. To replace the turbo after it would cost 3k. Thanks all to help with my decision Happy new year to you all

    Should invest in replacing cracked head

    Thanks Ne-Max Yes I agree the price seems more then far. He did tell me he is upgrading the head bolts. He told me if I wanted to use original it would only save me $200.
