Summertime Blues, or, coping with vapor lock and OEM Options

[1970 Neun vierzehn]

I've posted this query here 'cause I figured maybe there would be no smart-a** replies that would be forthcoming from the "garage" forum.

Yes, I know about the front trunk placement of the fuel pump, but for a 70/4, that's hardly original. The only "trick" I am aware of is keeping the fuel tank mostly full, thereby lessening the effect of overly warm gasoline returning to the fuel pump.

Last Sunday, after a particularly spirited drive of some length, and exiting the interstate with about a 1/4 tank of fuel, the dreaded no-idle, sluggish throttle response at low rpm, and frequent stalling made the last few miles challenging. Thankfully, traffic kept moving, as I'm sure that had I been caught in lots of stop-n-go, the 914 would have died until things cooled down.

So, in the interest of keeping things original, does anyone have any other suggestions, if not to completely eliminate, but at least reduce the likelihood of vapor-lock problems?

My 73 pump was mounted on the firewall by one of the PO's. Was ready to fall off. I put it back in the stock location. I get an intermitant issue when it's hot. After I drive the car for a while, shut it off then let it sit, when I restart it the idle wants to die. Issue lasts a couple minutes till the car warms up again. On Brad's site, he mentions that's a problem due to the heads cooling down at a different rate than the engine. Thinking it might be more vapor lock related though. Would using that silver insulation help reflect heat from the pump? Any type of air deflector available? Curious to see how you resolve your issue Paul.
