Gasket Help

[marksa1458]

Looking for help on the general process of replacing gaskets - Do they typically go on dry or do you use some sort of goop? If you use a goop any recommendations on the type to use?

Right now changing out the gaskets in the fuel pump on a 1968 Mercury 500 2479530. I also need to change the powerhead to mid section gaskets, replace the water jacket gasket and want to rebuild the carbs...

Also, for those gaskets that are paticuraly challenging to remove, what is the tool of choice? Do you scrape off with a razor blade? How clean do you have to get the surfaces?

Appreciate any guidance - many thanks.

Dude you need to find an OEM merc Manual for that engine/motor.
Way too many Questions to answer. Try ebay. Just bought a manual for 10 bucks. Got to have serial number.

I use this stuff (aviation permatex) sparingly

it will fill the voids if you have scratches, I dont think you are supposed to use any kind of liquid gasket when replacing fuel pump diaphrams, put on dry.

as with any kind of mating surface with gaskets the old must be completely removed then cleaned with paint thinner/ acetone ....something of that nature, i use a razor blade with a holder and if its really on there spray some gasket remover on it...careful its like paint stripper and burns

like dukdown said most of this is in the manual

All gaskets go on dry on a inline engine... If you have the pink gaskets on engine use a scraper or chemical gasket remover but do not wire brush/scotchbrite them as I have heard they have some asbestos in them...and wear a dust mask and glasses.
