I have a short section of rubber hose just before you get to the tbi. I added a fuel pressure guage a few yrs ago ended up cutting the line and spliced with it with rubber. I"m getting ready to put  a new engine in and since it will use a higher flow fuel pump I was going to couple the fuel supply line back together with steel line. Iknow should have did that to begin with ha!
