Ive got an 86 s10 with a lq4 4l80 swap. Got my plug and play wiring harness from current performance and it fit perfectly and was the easiest thing to do on this swap but my problem is when I was cranking the engine it wouldn't fire. I have, obviously the 340 pump, corvette filter/regulator all -6 an feed and return lines. Its a returnless fuel system dont know if that matters but when I pulled the feed line off the the sending unit to recheck the wiring fuel burst all over me. So its seems its feeding it but I have no pressure. Whats up?

Plumbed wrong? Using all -6 could allow hoses to be crossed, etc.

Thought of that but ive got the feed line going to the 3/8 line and the return going to the smaller line. Aeromotive calls for a -6 feed and return.

Aeromotive said he thinks it vapor locked. To try and crack the fittings to bleed it. I guess we'll see.

It was vapor locked. First time ive ever seen it act like this. Because before I would have a buddy turn the key to prime it while I had the Shrader valve opened to bleed the air. Apparently by cracking the AN fittings it allowed it to truly bleed the air out. Oh well lesson learned. Fired right up once I got the air out.
