    I dug out my Autopulse fuel pump to look it over some and possibly try to find Ethenol safe bellows and other parts for it. I did a search on the HAMB and the only place mentioned as possibly having the parts in an older post has discontinued making parts for them http://www.autoperformanceengineering.com/html/bel_pump.html . Anyone have any other ideas on where I might be able to get parts. Thanks Rod

    Best electric fuel pump ever made...imho. I have 4 of those ( 3 Model 500s and 1 Model 300) and have rebuilt them all, one of which is on my T roadster. I have not had any issues with mine yet ( been on since last July) and haven't seen any corrosion at all...though I do need to checj it again.

    Gasket kits are available, but I have not found a source for new bellows. The early 300 and two of my 500s have copper bellows, but my newest 500 has rubber bellows....and you can imagine what that looks like, so I have been looking myself.

    We don't have really high Ethanol fuel up here (5 or 10%) so it doesn't seem to cause much issues here. What % do you get at the pumps?

    What model is your Autopulse?

    10% here, also have some without, but I wonder for how much longer. Thought this would be a good vintage piece for something I am working on although I am not sure which one to use it on. Not really nice enough looking to be under the hood of the delivery without alot of polishing. Might not be needed for awhile on the AV8 coupe as adding a 2 carb setup likely will come later so I can get by with a mechanical pump for awhile. Rod

    How do you know what model they are? I have three that appear to have a factory type of manifold on both the suction & discharge sides. Any idea what they would be worth?

    I did a search on e-bay last night and they are worth anywhere from $30-$400 depending on condition, model and voltage, so I really can't tell you much more. The Model number on mine is part of the aluminum casting. Rod

    The model number is usually cast on the center valve body, below the domed filter cover. Should have manufacturer's name and "Model 500 or 550" cast there as well. If it doesn't have a model number...it is most likely a older 300.

    We have mostly 10% and I have never had an issue here. Mine is under the hood and they look great polished or not. The Autopulse was the hot setup in the old days....all the old hot rod guys in the 40's and 50's used them because of their reliability and because they were built like aircraft components.

    Now there may be some exceptions to to these, but this is what I have observed and studied.

    I owned a 1967 Piper Cherokee PA-180C private plane several years ago.
    I was surprised to find an Autopulse electric back up fuel pump on it that it
    was factory equipped with. It was identical to the one on my high school hot rod
    that I built in the early 60's.
    I would bet parts could be found through aircraft parts suppliers.
    Be prepared to pay premium prices though. Everything aircraft must have FAA
    certification to be installed on planes.
    Try a Piper Aircraft repair facility for parts.
