TBI fuel lines

[Mastiff]

My 83 has TBI and a tank from a 1990 IIRC. I've been running the original 1983 steel lines for fuel: rubber hose from tanks to factory steel, then out to 1990 fuel filter (with hose adapters), then hose up the to TB. Even though I had a carb, I have had a return line all along.

My biggest problem is that the angle of the 1990 sending unit outputs is off from the 1983 steel, so I ended up making a full loop of hose once around the sending unit to make the connection without a hard kink. The connection at the fuel filter is a slight kludge too since I had to attach hose nipples to it.

So my question is, has anyone simply bought TBI year steel lines and hooked them up? I think someone told me that 1987 was still on passenger side. I'm looking for better options.

My 90 Suburban has the fuel lines on the passenger side. I bought all new ones when I did my frame swap because when I was young I just cut them all to hurry up the process , so I had to buy all new lines to swap on my 80 frame.

Where'd you get them? I just checked LMC and they don't have them.

The other part of the question is whether they would swap easily between years.

Inline tube has stuff listed. The prices are high, and no pics. 1987-89 are separated from 1990-91. Is that when they switched to driver's side? Anyone know what the "3 rubber connections" are? I'd expect the main fuel line to have connections for the filter, but not rubber. I thought these lines had pre-crimped flex lines at the tank and TB ends.
