Does it make a big difference to paint the fuel tanks white while I have them out? Would it be worth putting that that $75 pail of ceramic coating paint from Lowe's on them or just leave them as is ? I think I read some ware that coating the tanks was a waste of time and money? If it doesn't make a noticeable difference I'd just as soon not mess with it. I sure don't want to use spray foam or that silver matting.

G'day,

JimB painted a set of tanks with Lizard Skin paint for a customer that was having vapor lock problems on his GMC. The customer
called back a day or so later noting that he still had vapor lock problems, HOWEVER, it took longer on a hot day for them to occur.

Regards,
Rob M.

We handle another brand that has higher heat rejection than most.
I have received positive result.
Sometimes the big name company spend more in advertising, and not enough in
material.

The way I'm reading this is it may help a little with the right stuff and the Jims have a source ? Rob are your tanks coated?

Before I re-installed my tanks a couple of weeks ago, I sprayed their tops
with black paint and their bottoms with silver. Ugly'r'n original sin, but
who knows, might help a tad by reflecting a bit of road heat. At least no
one but me has to look under there. :-)

Roy,

Regarding JimB's customer I'll put it another way:

It's 100 degrees / your coach develops vapor lock problems after 1 hour.

You paint your tanks with Lizard Skin

It's 100 degrees / your coach develops vapor lock problems after 2 hours.

The Lizard Skin paint delayed the onset of problems by and hour.

The temperatures and times are made up NOT ACCURATE OR CORRECT.

The paint JimK sells I have NO experience with.

Regards,
Rob

your going to need to be ready for this - - - heads up -

it was 103 degrees today in L.A. this means this high pressure will be over you all in a few days.

so get ready for testing that vapor lock design or drive at night. good luck it is hot, hot, hot.

it was like that for 3 days here, so it is a real heat wave coming your way.

Karen put me onto some stuff that has an insulating factor that I plan on doing while I have the tanks down. I must say those old tanks look good as new except for a little dirt. Mickey its been 100 most of the summer please keep it down there.

My worry about insulating the tanks, if it takes longer to heat the fuel to the point of vapor lock, wouldn't it also take a longer time for the tanks/fuel to cool down again in an insulated tank?

I thought about that. I guess after it heats up you just top off the tanks with fresh fuel.

I painted mine red on top and white on the bottom. I did not use any type of special reflective paint, just Krylon Fusion. I like to think it did some good, but I can't say for sure. I had time to do it and that's the way I like to do things when I have the time.

After a drive cross country with bad vapor lock...

I had the tanks dropped, coated with Lizzard Skin, then diamond plate heat shields, then oversized braided steel fuel lines with insulation over the hoses. And a pusher pump.

No problems since.
