Fuel pump, No start Options

[Erich]

Hello all, just picked up a 1974 1.8l. New to 914’s but have owned several air cooled VW’s. The 914 has been stored for several years. Just pulled out of storage when I bought it. Will run on starter fluid only. Technically it is a one owner registered car as I have the original owners signed title and as far a si know, it has never been registered by anybody else. Appears to have original 3 port fuel pump. I checked that it does get power to the connector. I then hooked 12v directly to pump, no sound. Gave it a few taps just in case. Seems do is dead. I will. Pull old pump, probably go to a 2 port as easier to find and cheaper.

So took the dead pump out. Out of curiosity, Pulled the top off, hooked 12v and motor spin, reassembled and won’t spin. Ordered a 2 port and will relocate, not sure where yet.

so its locking in the roller cell section.
interesting.
that has to be done up very carefully.
trying to remember.
but possibly the o ring seal has collapsed such that the little flat cylinders inside are being compressed and so its all like a locked up vice.

i've pulled several of these apart and rebuilt them.
(but so lazy i have not reinstalled the original one back in my car (IMG:style_emoticons/default/biggrin.gif) )

even so, if you get that to work you might find that after you do get it to fire up it leaks out of the o-ring seal where the power connection is. sometimes that can come good if the new fuel soaks it and causes it to re - swell. but......you know.
and thats the hard one to replace. complete pump tear down to get to it.
very involved. but can be done if you feel like going deep investigating.
i have left a thread of my adventures in the other section of site.
can post a link if you are vaguely interested.
