Builds 86 Xtra Cab Build (4Wheelunderground 3 link front, 4 link rear and 3.4 swap) (4 Viewers)

This is interesting. I built a PS reservoir for Snowball that wouldn't stop cavitating, so I replaced it with a Lee PS part. I set mine aside with plans to look into why at some later date. When I built the reservoir I built it with a simple vent tube that has no restriction. I am very tempted to add an NPT boss to the reservoir and try it again with some positive pressure. See if that stops the obvious cavitation. My eyes aren't what they used to be, so these welds aren't pretty. However, they do not leak - which is most important to me.

Positive pressure tanks were the norm on heavy machinery. Multiple high flow pumps though.

I would think it's not an issue on a stock automotive system or they would pressurize it. Maybe the high flow pumps are the issue. The fluid used also matters.

I had a couple days that I watched our granddaughter and was anxious to get going on this. I was happy when my parts tracking showed it was out for delivery. I had 15 items coming and I got a little box with ONE fitting. The invoice showed the rest coming from Texas the next day.

Then I got the OEM fuel filter I ordered. I noticed that the pinch bolt seemed to be on the wrong side. Maybe why I got it cheap. Anyway, I cut off the weld nut and put one on the opposite side.

Since I was still waiting for parts I made a small bracket to steady the end of my heat shield. I thought it might buzz and drive me nuts. Better to secure it while the cab is off.

 

[aztoyman]

I bought a tool to secure stainless steel zip ties and it came with a bunch. So I used one to replace the plastic zip tie I temporarily put on the fuel pump hanger. I replaced the old tie wire I had used for my exhaust wrap too.

My parts finally made it and I got to work figuring out where I wanted my fuel lines and filter. The return and vent lines were originally attached to the floor of the cab. I didn't want to be laying under the assembled truck trying to bend up fuel lines. I had to look at pics with the cab on to consider the available space and where I could easily get to the filter. I mounted it under the hood on my 88 but that's not an option here.

I somehow forgot to order a couple fittings so that's why the hose isn't attached below the tank in one pic.

I had to modify the bracket I made to secure my brake lines. There's not enough room to run the fuel lines over the brake lines.

The bracket I had to modify with a notch. I used existing bolt holes in the frame to attach it.

The inner most tube going off on its own is the vent line. It will go up along the firewall and ultimately to the evap canister.

Nice work as usual !

 

[Mudder]

That’s just gorgeous right there!

 

[aztoyman]

Thanks. Compared to steel, this NiCop is a joy to work with.

I just need to leak check the system and I can try to get it started...IF I get the harness out of the 88 cab. Man I'm tempted but I really don't have room for all the dash parts. I don't have an air filter solution yet or the steering reservoir figured out. Getting closer.

 

[aztoyman]

I'll end up putting some fuel line or shrink tube over the lines in a few spots for a little extra security against any possible rubbing.

I used a bunch of salvaged OEM clamps from other trucks. I just had to enlarge the hole for the 3/8" line.

nice work. very clean.

 

[aztoyman]

Thanks man. I need to paint the tank bracket, make the new straps to replace the welded ones and get new rubber liners on them. Paint anything I recently welded on and then get busy on the cab.

This will keep me busy next weekend. Dang trees.

Dam tree work never stops at my house
And it's my own dam fault I planted every one of them 25 years ago, there's 18 of them. Oaks,Elms,Redwoods and olives

 

[aztoyman]

Ha ha This is a step up. The last time I put a 12' ladder in the back of my truck and used a 12' pole saw. I can't reach anymore. I need more than a helmet.

One with a propeller.

1-800-THE-TREE-GUY.......



I was just today replacing the m/c to prop-valve lines on Snowball that I made in 'get it driving' mode and haven't liked ever since. Had to replace an almost new M/C as it was doing something strange and figured while I'm in there.... Hence the truck's name. I used the Ni-Cop that I used for the rear axle, only this time I was double flaring it instead of AN flares. Really nice stuff to work with.

 

[aztoyman]

@ntsqd The flaring tool I'm using does double flares in 37 degrees or 45 degrees depending on the die set you use. It worked great on 3/16" and 1/4" but I'm fighting the 3/8". IDK if I got a bad set of dies or what. I'm waiting for a reply from the seller.

The down side of this tool is it is big and has to be clamped in a vise. No close quarter work for sure. A compact 37 degree flaring tool would be nice.
