6.2 diesel lift pump lines

[86D30]

I’m having a lot of trouble with the threaded line from the filter to the lift pump (bottom right side of block) on my 1986 Chevy k30, quick question for the professionals, is this line under serious pressure? Or would I be able to remove a section of it and replace it with rubber hose and clamp it back together? It appears to be rubber at the filter and to save a buck I’d like to make it rubber underneath as well.

any advise is appreciated! Thank you in advance

Steel because it is near the exhaust and under pressure.

Bend a new line from a straight stock piece and double flare the end.

Agree. I believe it is a union fitting he needs.

Swap it out for steel jacket and use Kevlar hose wrap.

To answer the PSI question, approximately 7lbs so neoprene hose and clamp would do BUT steel is better!
