Mechanical Fuel Pump - Basic Install Question

Recommended Posts

I searched a number of times, but couldn't find the answer to my simple question.

When installing a mechanical fuel pump, how is the Permatex -  "Permatex 85420 Permashield Fuel Resistant Gasket Dressing & Sealant", applied?

Is it applied to each of the four hard surfaces? OR, each side of the two gaskets?

Roughly, how much is used on each surface?

Also, do I lubricate the pump before installation?

Any help is appreciated.

 Your choice as to which surfaces get the dressing. A thin coating is all you need. Any more than will result in dressing squeeze out. I've installed pumps with no dressing, just a bit of grease on the gaskets and had no leaks. No need to lube the pump.

Well, I got the old fuel pumps off and realized that the PO didn't even have the spacer installed.  I ordered a new one and hopefully will have her running next week.  I hate waiting.
