After the recent discussion on the 3B side of this forum concerning dual stage fuel pumps and vaccum wipers I decided to upgrade from the cheap generic single stage glass top fuel pump I recently bought. I went back to the parts list and wasn't having much luck determiming exactly what I wanted. And then, low and behold I ran across a old post by Ken (oldtime) who knows everything and there were my numbers I was looking for.
I started looking and couldn't find any of the first two numbers but I found several of the AC 9562 on Ebay. I'll tell you PRICEY little suckers for a fact at 200.00 give or take and up!! Negotiated a new one in the box down from what he was asking to less than half price by explaining truthfully my wife was going to KILL me!!! Still pricey but original and if I ever finish the thing, get a top on it and hit the road I won't have to worry about my vaccum wiper or wipers fading out during a rain which could very well become a safety issue. Herein lies my question. Shouldn't I now be looking for a modern rebuild kit with neoprene diaphragms to compensate for modern gas or run it as is? ![]()

The DJ3A's used a single action metal top fuel pump, no vacuum wiper type! The unusual DJ3A intake manifold accommodates the vacuum wipers and is much, much more reliable! |

The AC 9562 vacuum-fuel pump came in today. Appears to have multiple or layered diaphragms, you can see them sticking out in a couple of places. Even though the box was a bit rough the Nos pump still looks new and what I could see of the diaphragms felt soft and pliable. My intentions now are to use it as is, try to stay away from ethanol as much as possible and in the meantime keep an eye out for a kit just in case it's ever needed. |

I don't llike the adulterated ethanol fuel either but would not worry about it effecting your NOS AC fuel pump. My experience shows that the original OEM diaphrams should easily outlast your needs. |

Emergency Question: The fuel pump came with two gaskets but no spacer. I installed it without a spacer but now I'm nervous about it and wondering if I did the right thing? |
