MFI hard lines- interference with throttle
 

Hello,

After 20+ years of carbs, and about 10 years of having MFI parts in a box, I am finally reverting my car back to MFI. I test fit the hard fuel lines and throttle rods/cables and noticed that the rod was rubbing slightly on the #3 fuel line. I managed to nudge the line in a bit to give myself 1/4" of clearance, but would like to see how the lines should align.

I searched all over, but couldn't find a good shot from the front of the engine looking back. Can some one post some from the same angle?

Note: Those pictures were before I bent the line a bit to give me more clearance.

Thanks,
Neil

Neil,

I can try to get a photo later today/tomorrow.

My .02 - the offending line looks like it is bowed. You should take it off and 'bow' it the other direction. Carefully. Looks like engine is out so now's the time.

Thanks Matthew, it looks bowed to me too.

I am trying to determine how much I need to bow it in the other direction. I'll look forward to seeing your pictures.

Sorry, the photos were a bust. Just couldn't get the phone in there. My line that goes to cylinder 3 looks like it runs at a different angle or plane that the longer 2. It's under the other 2 lines and nowhere near the throttle linkage. Your lines all look parallel, different from mine.

Matthew is right; that line is tweaked, untweak it.

Helps if you loosen and re tighten, sometimes.

Here's a pic from my recent teardown- it isn't quite the angle you're looking for, but does show that the 3 lines run parallel and in-line (lower right part of pic). Suggests that the others are correct, one of your lines may be a bit bent outta shape.

Here are a few pics of my lines, removed from the engine and cleaned up a bit. Hopefully you can see where they should/shouldn't be bending.

Thanks for the pictures.

Interesting that the parts manual only shows that bracket/clamp on the right side of the pump and not the left. Guess I need to order two of them.
