The highest compliment I can pay Darryl is that he does it RIGHT. His attention to detail and originality is an inspiration. He's also a hell of a nice guy and has been forthcoming with great information for my own SWB restoration.

Great Job Darryl!

Very nice indeed. I like the primer pump in the engine compartment. Reminds me of outboard motor boats!

It is an outboard motor hand primer pump. Unless you install an after market electric pump in your 356 or 912, you get the pleasure of cranking your battery down refilling the carb float bowls. Today's gasoline blends are very volatile compared to 40+ years ago.

If my 912 sits longer than about 7 days no amount of
cranking helps. I can pour a trickle of gas down the carb
throats and it'll fire right up. I really need to install a primer
bulb. Or just make time to drive it more

Alan, if that's the case, you might want to check the output pressure of your fuel pump. I'll bet that it's low. Remove the pump's intake fuel line and gently blow into it however you wish. If the tank outlet is plugged, drain and flush the tank. If not, then the pump needs a rebuild. Ed Fall rebuilds 356/912 fuel pumps these days if you don't want to.

Neil- I drained/flushed the tank last year and installed a new
intake screen so I know that's good. I suspect it's an old, stiff
pump diaphram as you said.

Alan, we've sort of grabbed this thread so I'll sign off with this last comment. Just in case you hadn't thought about it before, with your fuel pump a bit sleepy in the pressure department, there is a greater likelihood of the 912 getting vapor lock in hot weather/slow traffic.

The outboard motor squeeze pump will aid in start-up but the head-loss due to its check-valve will slightly exacerbate the occurrence of vapor lock.

Saint H.C. Pellow recommended a new fuel pump with an engine rebuild and I agree. Pouring fuel into the carb by hand might anger the Porsche Gods one day so please be sure to have that fire extinguisher handy!

This works well , it was the first thing i added to my 66 912 when it arrived . as the car is parked for future resto ( long story,bad purchase ) but the engine is a fresh rebuild. so i give it a run each month to keep it fresh. The outboard pump bulb makes it easy to kick in to life each time.

yes, it's a great site. Well worth following. I've been watching over the full restoration of the bahama 912 for a number of years, Darryl is meticulous, and a good guy ! Interesting to look at his detailed costing (to the cent) of the restoration, and also his tracking down of the original owner.
Next restoration is a 356 (though there's an early Beetle to do also !)
