Lift pump - rtv or gasket?

[homelessduck]

I just bought a new lift pump because I think mine is going out. I didn't think to check the box for a gasket though I did open it up and look at the pump. I get home and look over it again, and realize I didn't get a gasket. I live out of town and I really don't want to risk having it go out on my way to/ from getting the gasket.

Can I rtv it? If I have to use a gasket I will.


Also, anyone have any experience with the " precision fuel pumps" brand?

I use just the RTV. Done it 3 times and no leaks so far.

Make sure to use good rvt when you do this. I prefer the copper one.

All I have is ultra black, which wouldn't be very fun to get off next time. I think I'm going to run to town and hope for the best. I can't really wait for it to dry now that I think about it ..

Thanks guys.

gasket with a small amount of sealer, emphasis on small.

Have to let it dry or you will be asking for problems thats the bottom of the block if it doesn't dry its very easy to loose all you oil in a hurry an not know it.

I decided to have someone pick it up for me so I don't take out the engine. The parts guy mumbled something about it being the same gasket for a 351. Does that sound right?

there are 2 mechanical fuel pump gaskets, the type like ours and 99 percent of other american cars ,and the odd one is the 351M 400M ford style.
So yeah ,ford chevy dodge ,rambler all the same type gasket.

Yes, and get some Aviation Form A Gasket too, that's the bomb that stuff....

Take a look at this thread,

Instead of block of plate consider the fuel pump the plate and duplicate that procedure.

I swear by the elephant snot stuff....it's awesome, and unlike proverbial RTV that can have small nuggets form inside where you don't see and it gets squished out, you wont have a problem with said RTV nuggets breaking/falling into pan and getting into oil pump or oil galleries...

I'm not a particular fan of RTV though it has it's purposes!

Good luck and glad your getting a gasket!!!!

Copper plus is what I use for the oil pan gasket but the surfaces must be clean. For that I use brake clean cause it wont leave a fry film.. Thats how the factory did our oil pans but we can still buy a pan gasket... Thats a bad thing.. Never ever use a cork or rubber pan gasket... They will leak on you .. thats a known fact and a very sad one to boot... A leaking oil pan requires the pulling of the engine to replace it properly.

Just cut out a gasket from a thick piece of paper. My favorite is an old Oil filter box. Take 2 minutes to make one.

Well, that fell through .. So I'll be heading to town tomorrow to get the gasket. I'm going to change it in the parking lot instead of driving all the way home hoping I make it.

Hint, invest in some anaerobic gasket maker. For situations where a gasket is not available it works ablout a zillion times better than sillyscum and can be put into service immidiately. The stuff cures very quickly in the abscence of oxygen ( i.e. where the joint is squeezed together) use VERY sparingly a thin bead will give a good seal

I'll definitely look for some of that anaerobic gasket maker, thanks!
I made it to town and changed the pump in the parking lot. It took me longer than expected because I couldn't seem to get the pump arm under the lobe. I was expecting to feel resistance but never did and finally just assumed I got lucky with it shutting off in the right position. It hasn't blown up yet so I guess it's aligned correctly. I used a thin layer of permatex aviation sealant on the gasket, it doesn't appear to be leaking.

It seems to have more power which is always nice .

Thanks guys!
