What did you do for fuel?

iirc the 87 sender still has the TBI style connections, just regular "push on" hose nipples for rubber line and clamp. I keep finding square body guys saying to use the 87-91 blazer sending unit, but with those nipples I don't know what they are doing for feed line.

I have 3 trains of thought on this, none of which are tested, so theres my disclaimer.
1. slip extra FI line over the nipple, and use 2 fuel injection clamps. Doesnt' sound the best but they DO hold very well, even at 60+psi, do at your own risk.
2. You could clip off the nipple and try to use the "hard line" AN fittings on the "stub" from the fuel pump. If the pipe OD is right, this might actually work just fine...never done it..do at your own risk.
3. Have someone braze or tig AN fittings or Pipe fittings to the sending unit, then adapt from there. The most work, most cost, and most professional. Still at your own risk.

If all else fails I was thinking of option number 2. I just wanted to ask before I pull the trigger. This is my very first swap EVER, which I am doing all by myself, and it's a lot to take in LOL
