PostPosted: Sat May 31, 2008 4:59 pm    Post subject: Broken Fuel Pump Flange Reply with quote

I found a couple articles related, but have a specific question:

Removing the pump flange, it seems like it was broken for a while from the looks of the break. The other piece is firmly seated inside the guide. If I put the old flange back, is that a major problem down the road, or should I try to get the old pieces out with a lag bolt of some sort?

If the old flange goes back in, it will seat tight against the internal piece of the flange, so is that considered an option, or just do the work to get it out?

Thanks!

I recommend removing it and replacing it with a high quality one from CB Performance.

I have attached a photo of my "intermediate flange removal tool."

Doesn't look like much, but it worked great. I believe that the socket is 1 1/8". The lag bolt is just a hair larger than the inside diameter of the flange. The lag bolt should be just long enough to reach the broken piece, plus about 1/4" to grab the broken piece and pull it up.

Go slow. You do not want to break it into many small pieces.

Also, I recommend keeping all of the broken pieces so you can reconstruct it to make sure that no "large" pieces are missing. If all major parts are accounted for then you can chuck it.

This discussion on Good Quality Fuel Pump Push Rods may also be useful.

Good luck,

Pat (66foot)

I've been running my 71 for a while with the lower section of the flange still in the guide and a new one that's had the lower section cut-off on top. No problems. Mechanically, the only issue to be worried about is whether there is any binding of the pushrod -- are the top and bottom sections well aligned. For you that should not be an issue either.

The lower section will not fall downwards as it is a tapered guide and will not come up either. Oiling is not impacted.

I think it was designed as one piece only to aid removal and installation.

You guys are great! Lots of good suggestions. I went at it with Pat's method - the lag bolt and socket. Seemed to be working great, until it didnt pull it out...tried it multiple times, no luck. That thing was in there! So I gently chiseled a piece of it out. The whole thing fell into the sump where I'm still looking for it! I'm not seriously worried, as it's plastic, BUT - it's still something I would like to get out. Judging from the gunk I found in the screen, it shouldnt be too big of an issue..but I will find it.

Thanks to all for your advice - great as usual!
Curt

Bummer!

By your description it sounds like the intermediate flange was fairly brittle. It is probably bakelite.

This discussion regarding a piece of fuel pump flange fell into top of block and recommendations on how to extract it may be useful.

Good Luck,

Pat (66foot)
