'78 Cj5: a few questions while I wait for parts

Made a little progress on the newly acquired '78. Got the new tank in, the MC 2150 rebuilt and reinstalled, some wiring redone on the tail/brake lights and thought I was to actually put a few miles on her. Nope.

Topped the thoroughly rusty radiator off and let her come up to temp, and watched the water pour back out from the water pump and several spots in the radiator. So radiator is at repair shop and water pump will be here Monday.

So in the meantime, a few questions....

1. Found several places that do a complete bolt kit for the 304, but I just want to replace the eleven bolts to the water pump right now. Anyone know of some place that sells just this kit.

2. Fuel lines. The metal lines run up to bottom of the firewall, and then are soft line from there: over 3' feet each of supply and return lines. Is this a stock setup ? Just curious as I am going to run some hard lines where I can: that is just way too much unsecured soft fuel line for me.

3. Air injection system. When I removed the smog pump and the other hundred items attached to the water pump, it didn't have the belt to it and probably doesn't work. At the top of the manifold tubes, is that a check valve ? I assume to prevent exhaust from back flowing through the emissions system ? If I remove the hoses from it, can I just leave the manifold tubes/check valve and run it this way ? Really don't want to try to remove the tubes based on what I read on here. (I would just test this theory, but have the radiator, water pump, PS Pump, etc removed)

Thanks in advance for any help !! This site is full of info: have read close to 400 back pages. I read and bookmark a few a day !

1. try local auto parts or hardware store for those bolts. Make sure you know the size and thread.

2.Stock with the mechanical fuel pump the hard lines are right next to it with a small section of rubber. The hard line then goes to the fuel filter with small sections of rubber.

Im not sure what part your talking about on 3.

Thanks. Hardware selection in town sucks: was hoping for a pre-sized kit available.

I will make up some fuel lines and replace as much soft line as possible.

The pic below shows what I think is a check valve on top of the manifold tubes. No problem: as soon as I get the water pump and radiator back in, I can see whether it stops any exhaust back flow. Just thought someone might know.

1. I'd recommend Totally Stainless. They sell bolt packages by engine component. I used there high strength stainless steel bolts, which are stronger than grade 8.

2. Already answered.

3. That is the diverter valve for your air pump system. It allows excess pressure from the pump to be released to the atmosphere, mostly during rapid deceleration. I do not think it will function as a reverse check valve. I think your best bet is to remove the air injection manifold and plug the bolt holes in the intake.

That sucks. I have a few stores to pick from a local mom and pop shop seems to have the biggest selection of hardware and will even special order me some if I buy a box. Fastenal and napa have stores a couple miles from me.

They are a quality business. I ordered their entire AMC V8 engine bolt kit for my 360. The bolts came individually vacuum packaged and labeled per engine component, which made assembly a breeze, and every bolt fit exactly as it should.

Yes, Totally Stainless is a good company to deal with and their engine kits are well put together in either stock type Indented Hex Head bolts, Allen Head, Button Head, 6 and 12 point Hex Head which are the better than grade 8 or ARP type hardware. I've gotten a many item from them in stainless to replace OEM hardware that corroded beyond use.

Yep. I will be ordering from them again. $24.00 (+shipping) for the 11 stainless bolts, priority mail, and I didn't have to leave the shop ! Doesn't get any better than that !

On another note, I treated what little rust there was on the floor boards, then stopped by the local paint shop today and asked them if they could look up & match AMC 7B (Mocha Brown Metallic). Mixed me two rattle cans in about 10 minutes ! Sweet ! The guys at Wholesale Motive rock. Was going to go with some kind of bed liner, decided to paint.
