HIH vs HOH

[va_redneck]

I am about to install a WVO system. I was sold on HIH but have read some posts where people are concerned about leaks. I live in the mountains of western VA on a back road that can shake your teeth out.

I am rethinking HOH but will a HOH work for me when it gets down in the teen’s which is common. Single digits is not common but we get a couple of nights/days down that low. Will a FPHE work well enough and will the hose flow from the tank with a hot fox and HOH.

Opinions and experience welcome.

i bought a grease car kit and have spent lots of time re-doing alomost everything. now im runing HIH from the wvo tank to the IP. and have had no issues with leaks. im also runing vo all year long. with no problems yet. if you go with the HIH hit up lows or home depot you can get a brass T fitting with threads on the inside. they come in all sizes depending on what size heater hose you are using. thread on a compression nut fitting using PEX or aluminum fuel line in side of it. you can get hose barbed things to thread on to the other parts of the T fitting. i uesd pex cuz its cheaper and no polermazation (i cant spell that work atall) issues. vo goes: tank through HIH to heated vo filter then HIH to valve A. clear fuel line (4 inches) to to lift pump. HIH from lift pump to IP. so when diesel goes to valve A then it goes to the lift pump and out through HIH also befor the IP. better for the winter. i have both vo and diesel filters wraped in soft copper coil to keep them hot. this winter im not going with a bloc heater. im using a in-line coolent heater. so it will warm up everything down to my HIH, copper coil around the filters and vo tank. i cant waite for winer this year! hope this helped...

My HIH consists of 1/2" air brake hose, which is my fuel line. The coolant flows through 3/4" heater hose. I get the air brake hose tape the ends and wet the outside with coolant (it acts as a lube) and slide it into the heater hose. Next I get two compression fittings the size is 1/2" copression to 3/4" NPT male. I take off the nut and remove the ferulle and drill out the fitting with a 1/2" drill bit, put some pipe dope on the threads and put it together. I have installed 10 kits so far like this 2 gave me a little trouble leaking coolant my fix was to put a rubber o-ring between the nut and ferulle.
P.S. I'm sorry you wasted your money on a Greasecar kit. I like their solenoids and they got a cool little filter but other than that [img]/ubbthreads/images/graemlins/vomit.gif[/img]. We installed one a Mercedes and he always has problems.

what kind of problems...

My system has my own take on HOH. I purchased 25' of CHEAP coolant hose and cut pieces to match the lengths of my installed hose. I slit each piece lengthwise and wrapped each hose segment secured by tie wraps. The now double insulation has given me cold weather protection. I've run it in ambient temps as low as 19*F without a problem. Another cold weather accessory should be a cold front blanket to cover most of your grill/radiator. The combination of these two makes winter WVO driving easy.

So this sounds more like super insulating than HOH . Are you simply preserving the heat from your pickup or did I miss something ?

Just double wall insulation to keep the heat in the fuel lines. My hoses are under the bed of my truck and subjected to ambient temps. In winter it really makes a huge difference. There are many ways to skin a cat.

Slightly off topic but I just received my diesel (93 F250) and receipts show a new front tank and the rear was empty . Would you consider replacing the rear tank with plastic and using it for WVO ?

I used the front tank on my 93!

I think this is less of HOH and HIH, and more of a HAH (Hose Around Hose).

I had all sorts of problems with my original HIH installation. I used stainless steel tubing for my fuel line... I used aluminim tubing for my fuel line... all with the brass compression fittings that connected to the classic brass "T" fitting.

It all started good... but all ended badly. After about 30-60 days, the natural vibration of the truck and driving just rattled up those compression fittings, and they started to drip.

In my third attempt, I used air brake tubing at the suggestion of Blue Mule (where is he?... I haven't seen him around?). That install worked for quite a bit longer, but eventually fell to the same fate.

Now, mind you, when this thing leaks, we're not talking about my being stranded on the side of the road somewhere... we're talking about a few drips of coolant in my driveway after I park, and me having to "top off" my coolant every month or so.

As always seems to be the case, Jason over at Vegistroke came up with a HIH design that works with no leaks... it's a slightly more difficult installation (meaning you can't drink too much beer when you make your hose cuts and your connections... cause if you screw up once you're screwed...)...

.. but it's now been over 10,000 miles and a COLD winter here in Northern Idaho, and not a drop of coolant has been shed.

His assembly is more expensive (in fact, VERY expensive).... but it's the last HIH install you have to do.

I've read about it and looked at it as well on his web site. Would it be long enough to do my rear tank and then be able to be modified when this motor moves to my Club Wagon ?

Actually, Jason sends you the pieces, you assemble it "on the fly".

This allows you to do any length of hose.

Do you think they would work for the rear tank on a super cab in your environment , pretty similar here in Michigans U.P.? And if so,is there a plastic tank and heated pickup close enough to custom fit where the rear tank and spare are ? (36 x 36 x 12)

You should put your truck configuration in your sig, so we can see what we are commenting on.

I know of no where that HIH won't work... (Vegistroke or otherwise)... it's just a matter of whether or not you want to run heater hose and fuel line separately or inside one another.

As far as tanks in the spare tire area, I think a few folks have taken Excursion fuel tanks and have managed to rig them up for use in their SuperDuty trucks... (but if pressed, I couldn't recall who did it or when).
