My square has the spacers. It can be 100 plus in the desert during the summer. The carburetors have never boiled dry. I have never had a vapor lock situation.

Once you install those spacers your good there forward. <br>

<br>
Hi All,<br>
<br>
.....<br>
<br>
Now for the vapor lock question (I've got dual dual Solex H32/34 PDS13 with <br>
stock brazilian air cleaner setup, recently rebuilt and rebushed, balanced <br>
and running perfectly): twice now when I've had the engine at full <br>
operating temp, parked it for 15-20 min, then returned to drive it, I have <br>
only been able to drive about a block before the engine dies (clearly a <br>
fuel starvation sputter as it chokes). The first time this happened last <br>
week, I could see that no fuel was present in the in-line filter, and in <br>
pulling off the line to one of the carbs confirmed that nothing was getting <br>
through. I could turn the engine over and over, pump the gas a gazillion <br>
times, and get nothing. I tried removing and replacing the hose from each <br>
connector at the carbs and pump, and then making sure that all of the hose <br>
clamps were tight.. Still the engine wouldn't start. Then, after about 20 <br>
min, I could see some fuel returning to the in-line filter, and the engine <br>
finally started up, and ran perfectly. Assuming that this was not a problem <br>
with the fuel pump--which to my knowledge either works or doesn't-- I <br>
surmised that the fuel lines were getting too hot somewhere, and adjusted <br>
the length of all the hoses so they weren't directly touching a heat source <br>
(such as the block, or shrouds/sheet metal) and in the one spot where there <br>
is still contact (the back edge of the sheet metal covering the stock oil <br>
cooler) I put a larger diameter hose piece around the fuel line to serve as <br>
a buffer. All was well until today, when the exact same thing/condition <br>
occurred! Aside from that single spot of contact with the sheet metal <br>
covering the stock oil cooler, there is no other contact between the fuel <br>
lines and heat source(s). I turned the engine over again and again, messed <br>
with all the hoses (removed/reattached/tightened clamps) to no avail... <br>
after about 20-25 min, at which point the fuel started flowing again, and <br>
the engine ran like nothing had happened all the way home.<br>
<br>
SO, my questions are<br>
<br>
1) Am I correct to diagnose this as classic vapor lock? I ruled out the <br>
fuel pump because it otherwise works perfectly. Correct assumptions?<br>
<br>
2) How could this happen again after readjusting all of the hoses in <br>
relation to heat sources?<br>
<br>
3) Why would this happen even if the lines did touch the block/sheet metal <br>
directly? On my old motor, the hoses from the pump to the T-splitter and <br>
then to the carbs virtually laid right on the block, and I'm quite sure the <br>
in-line filter and/or hose between the pump and filter touched the sheet <br>
metal above the oil cooler directly, without the extra hose to buffer. <br>
Plus, in the last year of that motor's life, I got the engine up to <br>
280-300F every DAY on my short commute before shutting it off, and still <br>
never had a vapor lock issue... again, with the hoses touching heat sources <br>
all over the place.<br>
<br>
4) Does cloth braided hose stay cooler in the engine compartment than <br>
non-covered fuel line? The hoses from the pump to the T and then to the <br>
carbs are cloth braided, but the hose bringing the fuel to the pump (on <br>
both sides of the in-line filter) is the larger-diameter <br>
non-braided/covered hose. This is the one that comes closest to the heat <br>
source at the back of the cooler, and that I have buffered with the <br>
larger-diameter hose piece. Could this be a/the culprit?<br>
<br>
5) If this is vapor lock, does anybody know any quick tricks to release the <br>
pressure/vapor and get moving again without the requisite 20-30 min wait?<br>
<br>
Needless to say, this has temporarily suspended my T3 Nirvana... TIA for <br>
any advise!!<br>
