Man, it's been a headache the last few days. Messing with the mechanical fuel pump, it works off the block just fine. Mount it, no pressure at all. Of course, initially I had it plumbed in reverse! In my defense, I'm so used to having the inlet facing the rear of the vehicle, that's how I set it up. And since there wasn't a mechanical pump on it when I got it, I didn't know any different.
Anyways, after too much frustration, the electric pump went back on. But, unlike the previous installer, I put it underneath the body. Pumps like to push, not pull, and it was mounted up high on the firewall before. Surprised it never burnt itself out.
I'm not really surprised at the fact of the original lines are all still on it. So, let's use em! Yes, I'll run some fuel through it before I hook it up to the block to get all/any crud out of the lines. And for now, I plumbed it for the CJ tank until I can get the big tank completely finished up.
And the original shut off valve (minus the handle) was still attached, so let's clean that up! Works too, may need some graphite packing, won't know until I put fuel through it. And I need to fab up a handle, I have the donor piece, just gotta do a little cutting/welding/make it pretty.
