You guys rock... thanks.  Almost got the AFM hoses installed.

AFM hoses installed.  Took awhile to get the pre-AFM silicone hose cut to fit right.  Moving on to the fuel pump. 

 

put more gas in the tank, 1 gallon may not be enough for the pickup unit to operate well. check it by trying to start a siphon and see if it continues from line that goes to the pump.

Comfirmed the fuel pump is dead.  The extra one I have works so it’s on it’s way in now.  That fuel pump was a pain in the butt to get off.  Lines were frozen on.  The fuel coming out of that old pump smells aweful.  

I also go the fuel rail off.  One injector has a screw that wont come out.  I’ve put PB blaster on he screw but no luck so far.  Will let it sit and try again.  

You could also run the pump supply/input hose out of a 2.5 gallon gas jug.  It's the output that's high pressure.  Let it run for a few seconds then blow into that ho's.  

I bought the new improved hex screws for the injectors from Nissan back in 2012 for $7.50 for all twelve.  Part number 01121-02981

Here's S30's allen head screws, better deal too. @S30Driver

You may have to cut a slit in it with a Dremel disc and use a flathead screwdriver.  Almost all mine did that round off bullshit. 

My memory is coming back!  Try a small set of Vise-Grips on it if the lubricate doesn't work.

Okay the hoses on this rail are dry and brittle. I’m pulling them all off and replacing them all. I hope I can get this thing back together. I’m also going to lightly sand off the rust and respray it with some black rust resistant paint I think. I’ll also make sure the lines are clear. This is slowing me down but better to do it while it’s off. Going to buy some needle nose vise grips for that stubborn screw. Then buy a Dremel to go the other route if no luck. Look at this mess.  Previous person didn’t use Fuel Injectors clamps, I’ll fix that.  These hoses were bound to leak at some point.

I used this a cheap high heat paint, about $10 a quart at Lowes.  Rattle spray cans also but I bought a $20 dollar gravity fed HVLP cup gun from Harbor Freight.  More miles per quart. 

Great progress!  I'm sure you know but in the spirit of site member Captain Obvious,  be sure to replace with fuel injection rated lines.   Also inspect the fuel lines in from the filter & the return for age/cracking.

The injectors are designed to work with no clamps.  The barb locks the hose on.  There's a full procedure shown near the end of the Engine Fuel chapter.  They just press on, it's easy.  5/16" hose.

Edit - they actually used too many clamps, marked in red.  They are the bad kind though, so better clamps for the rail connection is a good idea.

Before you install the injectors it might be worthwhile to flow test them.  Connect the hoses and electrical and power the injectors.  Compare the volume of fuel from each.
