    Building fuel lines... I'm using Earl's Performance Vapor Lock fuel line and fittings. The fittings are really nice, the end swivels too. The hose is EFI rated to 225psi and cuts nice. I used some Milwaukee shop shears to cut it. A little squirt of WD40 on the barb of the fitting and it slides right on. I also decided to use the clamps that get crimped on... Earl's has a set of pliers they sell as well.

    This will get bolted to the firewall and covered in heat shield...

    After my last post I hurt my shoulder... I've been forced to stay out of the shop and it's killing me... Today was the first day in about a week and a half that it's been good enough to do any work... And that's about as far as I got when things went wrong. In the above picture, the line on the right in the main feed line, the other is the return line. I meant to put the fuel filter in that line. Grrrrrrr... Also, where the lines bend up towards the bottom of the tub, they're trying to kink.

    Which leads to this picture... The remaining piece of fuel line was about 4 inches too short, about the length of the fuel filter. So I couldn't run the return line back to the tank... I added the fitting after the picture was taken... so I had to order more fuel line, a couple 90 degree fittings, and some more clamps... then it should be done. Once the submersible fuel line gets here I can set up the in tank pump.

    Other goodies showed up as well...

    This balancer is a smaller diameter than the original one. The distance between the balancer and the hump on the front differential has always bugged me. I've moved the engine as far back and as high as I could, the axle is moved forward, so hopefully the smaller diameter of the new balancer will be worth it. I had the old one off anyway and the new one was 150 bux, so I figured it was worth it... now that my shoulder is feeling better, I'm hoping I can keep moving forward. Thanks for checking it out, Laters.

    Fittings and hoses arrived the other day.

    The 90° fittings eliminated the kink.

    And I put the fuel filter inline as well. One of the ends could be just a tad shorter so the lines would stay parallel, but for now it's fine.

    Fuel pickup is plumbed as well. The pump is the replacement pump for a 1990 K1500. 5.7l truck. If I need a replacement down the road it should be easy to source a new one. The pump is wrapped in some foam and the lightly hose clamped to the channel that drops into the tank. On the bottom of the pump is the matching pickup sock.

    It all fits in the tank with the sock just resting on the bottom of the tank. The return line is about 20 inches long. I left it long thinking that it would be better than dumping the return fuel right onto the pickup. I didn't know if that would cause any troubles. I need to solder some longer wires to the plug for the pump, add a grommet, then weld up the unused holes next. I guess I need to start getting serious about the wiring now... Thanks for checking it out. Laters
