Properly, systems running DOT 5 fluids should have a bottom drain on the calipers. Without it, water can't be purged. Trucks like the CUCV have chrome plated caliper bores. Without that, seized pistons would be common. DOT 3/4/5.1 fluids a miscible with water which enables it to be flushed out...

Consider a head gasket an assembly of many gaskets. Fire rings to contain combustion pressure, coolant passage seals, and one pressurized oil passage seal. Is this gasket leaking in the vicinity of the oil supply port for the head?

I forget which one I bought. It was like this...

There is an active push to obsolete -5 fittings. I used to use a lot of field assembled fittings and the -4 were very fragile. You could break them by bumping into them so I replaced them all with -5. Now -5 is rare. I suggest using -6 for everything, even if it was previously -4 if your using...

I'm not saying the return fuel will approach 300 degrees. I'm saying that 200° is possible. That's too close to the maximum rating of a 212° rated hose and you should expect short life expectancy in that case. There are 3 types of runners oil hoses are constructed from NBR, HNBR, and FKM. NBR...

That will work for supply lines. I would recommend SAE 30R10 hose for the initial length of return line. Avoid worm drive hose clamps of you can. Use non-perforated or lined clamps if you must. The spring clamps are ideal Oetiker pinch clamps are great if you don't need them to be removable...

Just watch out for NBR rubber. It has a very short life on engines. This does not include HNBR which is second to Viton for longevity.

I don't think that chart is correct. Parker Triple Lok fittings are the predecessor of JIC which is 37°. SAE is 45 degree. You can use SAE female on JIC male if the threads match. JIC female on SAE male will leak. When you operate close to the maximum temperature rating you need to expect short...

The Aeroquip FC350 and Parker 201/206 are DOT brake hose. I have seen these used for fuel applications. I have never seen nylon tubing used for fuel. The nylon tubing uses push to connect fittings which have an o-ring so you need to be mindful of the o-ring material. The temperature rating of...

That hose is most similar to on SAE J30R5 hose. It's not suitable for return line applications due to temperature. It is not a substitute for Aeroquip 303 as it's not wire reinforced. Aeroquip 303 is for aircraft applications. I don't know the Aeroquip catalog well but I think FC350 is the...

If you're going to go the SAE 100R route I strongly recommend a hose with an AT rating for on engine applications. The hose I most common use is Parker 426 or Aeroquip FC-234. They are SAE 100R1AT rated. A note about using air brake tubing, it's not static dissipative and can generate quite the...

They're on Rock Auto. https://www.rockauto.com/en/catalog/chevrolet,1984,k30+pickup,6.2l+379cid+v8+diesel,1053021,steering,power+steering+pump+seal+kit,7407

There are kits available to rebuild the stock pump. It's just a shaft seal and reservoir o-ring. They are only a few dollars. Otherwise, the pump is a sliding vane type, these pumps can easily last 50-100k hours which is multiple engine lifetimes.

One of the reasons a particular line won't be recommended for a fuel is because there are too many governing bodies to comply (DOT, SAE, USCG, etc) with and no one line is able to meet all criteria. I work in commercial marine so I fall under 46CFR. Our rule for fuel lines is simple, they...

Parker Push Lok hose is absolutely suitable for most fuel supply, return, and lube oil applications on engine. Look for the Push Lok Plus HT 836 series. It's borderline for coolant applications if you're running your engine continuously but likely acceptable for most applications. Push Lok 807...

Basler AVC63-7 and -12 regulators have minimum field resistances of 9 and 5.25 ohms. These are very reliable regulators with high forcing outputs if that's worth the cost.

Basler AVC63-7 and -12 regulators have minimum field resistances of 9 and 5.25 ohms.

Consider using a polyurea based grease instead of lithium. They're superior for rolling bearing applications. They haven't caught on at the consumer level. Lucas X-Tra Heavy Duty is the only one I see at auto supply shops. I use Chevron Black Pearl EP2 in my fleet.

The point of isolated power on a metal vehicle is that it will keep operating normally with a wire shorted to ground. No current draw, no blown fuses. This is especially important on electronically controlled engines which many sensors and wires to potentially cause faults. This of course...

Your wipers turning on randomly would lead me to think you have a problem unrelated to the charger. Have you disconnected the charger to see if the condition stays or goes away? 24V systems typically use isolated grounds. This means you'll have a cable going directly from alternators, chargers...
