Hi
I need to renew my fuel pump gasket and have a few questions:
  1. Is the single paper gasket sufficient? Any gasket dressing suggested?
  2. Do I need to disconnect the fuel lines?
  3. And if so, can the compression fittings be reused, or do they need to be renewed as well?
Thanks

Bob
 
Paper gasket usually supplied is fine. Use shellac, permatex , or RTV. Fuel lines need to be off. Fittings should remain as you find them. Be sure to use tube wrenches to break loose and finally tighten the lines.

I have never owned a tube wrench and have changed at least a dozen + tube nuts. 1/2" wrench works fine for me.
I have now restored 4 TR's.

Got it, thanks. Later decided fuel lines should come off so I can properly clean flanges. Are tube wrenches same flare nut wrenches, because I have those for brake line work?

When you rebuild an OE fuel pump(recommended) the replacement diaphragms, as supplied, must have the attaching slot
dressed with a small file.Otherwise they will Not lock into the receiver arm properly.

I have not had a problem with my several rebuilds. However I am curious as to exactly what you are saying. Can you address this once more maybe with a picture? As to what parts you are referring to.

Hi

Back almost a year to the day. Plan on doing the fuel pump this weekend. Any preference on gasket dressing between these two choices?:
-Permatex RTV Ultra Black (#82180), or
-Permatex 2 (#2BR 80016) Form-A-Gasket non-hardening

Thanks

Bob
 
Re read my earlier post,I have done a bunch of these . I never put a sealer/dressing on the
diaphragm just make sure all is clean and trust in the tightening of the screws.

Thanks Maddog

I am talking about the flange to the engine block. Are we using two different terms for the same thing?

Cheers

Disconnected fuel lines and pulled pump on Saturday. Cleaned old gasket and RTV blue off both flanges (last mounted in 24 yrs ago) with acetone. Very thin smear of RTV Ultra Black on each metal flange. Reassembled finger tight. Waited one hour ( per directions) and torqued it down. 24 hours later reattached fuel lines with original compression fittings.

Started and drove car on Monday morning. No leaks - gas or oil. My problem was a bad oil leak on the engine block below the pump (dry above the pump).

Will report back in several weeks if block is still dry.
