No offence intended. I just didn't understand you.

If these work, then I will be selling, until then, "testers wanted"

The wrap could be installed without a lot of trouble.
The tube would have to be slid over one end of the HOH/TIH, fuel lines.

The results will be posted here, good or bad.

P.S. thanks for the offer $$$

OK,
I got 10ea.-9' wraps
and 2ea.-18' wraps.
Thats too simple.

FPHE,
I'm having a hard time understanding how 8% total area fits in?
Is it hot to the touch, ever? If it is, then we must cover it.IMHO.

Plantdrive is supposed to be sending me products to design around, one of which is the hydroforce valve..............Are all 3 hot?,to me, looking at drawings, it seems that only one or two could be hot.

please PM me your mailing address and I'll get started asap.


US snail mail seems to be the best way to send stuff long distance.


Respectively,
LCjeff

Success!

Well, it started off with a bit of failure, actually. Jeff sent me a beautiful 9' neoprene tube to cover a long section of 2 line HoH.

Unfortunately, nomatter what I tried, I couldn't get the hoses through the tube. After 3 hours of fighting with it, I gave up and sliced it down the middle to use it as a wrap.

Well, here's what I found:

Reflective bubblewrap, 15*C outside

10 minutes at 100 kms/hr:
- fuel temp at start of HoH section: 43.9*C
- fuel temp at end of HoH section: 35.7*C

10 minutes at ~50 km/hr:
- fuel temp at start of HoH section: 46.6*C
- fuel temp at end of HoH section: 37.9*C

Neoprene wrap, 11*C outside

10 minutes at 100 kms/hr:
- fuel temp at start of HoH section: 48.0*C
- fuel temp at end of HoH section: 45.5*C

10 minutes at ~50 km/hr:
- fuel temp at start of HoH section: 47.9*C
- fuel temp at end of HoH section: 45.9*C

I've got some pictures to load too.

Anyway, it's great stuff. I'm sorry I couldn't use it as-intended like a sock, but I found wrapping it still looks really good, and it's far more flexible that teh bubblewrap & tintape. I really like it.

Thanks Jeff!

I thought that it was going to be a problem, I think a wrap would be easier, and maybe more effective.
We'll see when Holdontight gets his wraps(126') and tests.

Your testing has given me hope and confidence. Thank you very much!

how did you hold the opened tube on and was there any uncovered areas?

Great info, although the ambient temps may warp the results a little,this looks like a winner.

we have been using some high-density foam (recycled sleeping bag mat) and wraping flat plate heat exchanger with it … helps with the metal to metal vibration …

anyway nice read lot of good info here thanks

Anyone in sub-zero places want a chance to test? (Siberia?)
This would give great results
But not many of us deal with snow every day.

Omar,(recycled sleeping bag mat) sounds like a great idea, although it's not laminated with cloth like wetsuits.
The laminate process gives abraision resistance and strength to the soft rubber, increasing it's longevity.

we have a lot of folks who have run a lot of miles with no cloth cover on the foam ... I think the car motor will need to be rebuilt before the foam mat wears out ... imo
keep up the good work thanks

I think the laminate would be helpful in many applications where abrasion resistance of the lines is needed...mine may be one of those applications.

I understand the wraps were shipped to me today. I'll explain more once I get the wraps applied. If I had the wraps when I was running my HOH, I probably could have simplified my installation by using fewer clamps to secure the HOH and not use some sacrificial hose pieces as buffers between the frame rail and the HOH lines.

Pics are worth a thousand words...so that will be posted/hosted when I report my results.

Thanks for updating the thread.

126' of wrapping, that's a lot of cutting.

I can't see it not helping speed heat transfer and hold temps for longer periods. (yea it's a double neg.)

1 and a half sheets, 2 and a half hours. Whew!

On the brite side, the wife seems to be comming around to the idea of smelling like fries, instead of Dino@#$%.........The price of fuel has somthing to do with it I'm sure.

I just couldn't wrap my mind around the results, so......

Jake reported;
Reflective bubblewrap, 59F outside

10 minutes at 62mi/hr:
- fuel temp at start of HoH section: 111.02F
- fuel temp at end of HoH section: 92.26

10 minutes at ~31mi/hr:
- fuel temp at start of HoH section: 115.88F
- fuel temp at end of HoH section: 100.22F

Neoprene wrap, 51.8F outside

10 minutes at 62mi/hr:
- fuel temp at start of HoH section: 118.4F
- fuel temp at end of HoH section: 113.9F

10 minutes at ~31mi/hr:
- fuel temp at start of HoH section: 118.22F
- fuel temp at end of HoH section: 114.62F

OK. Not as big a differance as I thought, translating temps helped me,
So that's 9' of HOH, insulated.

Jake, I've had a little trouble getting the hydroforse block as-yet, can you measure it for me, if you've got one?

Remember, "if it's hot to the touch, it needs insulation"
Not my Quote, not sure where I heard it.

LCjeff

Looking forward to images, hint, hint.........

LC Jeff,
I got the package today ..., and I couldn't wait to open and have a look. My first impression is that this stuff is going to be easy to install because it isn't too thick, very pliable and the outer cover should make the stuff easier to stretch a bit for a good fit/coverage. Obviously you know how to provide the best thickness to make installation easy for an existing setup! It isn't too thick and If I ever need to take it off, cleaning should be a breeze with a pressure sprayer at the car wash before I reinstall it.

I'm going to install it this weekend, complete with Before and After pics and before and after temp measurements. I'm going to pull the existing insulation on the hottest section of line feeding the fuel rail, which wasn't easy to install at all, and it doesn't look as good as this new stuff will!

I'm excited. I get good fuel temps now and fairly quickly, but I can't wait for the cold weather to see how much quicker I can get hot fuel, which will reduce the chance of cold VO issues from accumulating with each cold slug of fuel that hits the fuel rails at startup...priceless.

Although ambient temps can make some difference in the heat bled off (or not with the insulation), I think the temp gain of the VO with the addition of the insulation wrap will be proof enough.

I'm looking for advice on the key points I'm going to take temp measurements. Possibilities include the coolant heated fuel pickup, the coolant heated Davco 234+ VO input line, both ends of the HOH-HIH transitions and the input to the Hydroforce fuel selector solenoid. But maybe all this isn't necessary since I have a looped system. Maybe the time to max temp and the max temp is all that is needed for comparison since the loop will stabilize the temp throughout the loop once the VO is switched on within a mile or so of driving. Thoughts, suggestions?
