F.I. high pressure pump seal

[mike yirak]

I'm installing a new seal in the gear pump. The book says to apply a good sealing compound to the outer diameter of the seal. Does anyone have a favorite sealing compound for this spot? Preferrably something on the shelf at 7-11. Thanks, MHY

Mike,

I use silicone sealer in this area. I think the old time guys used permatex which is more difficult to remove. Paul Young

Hi Mike, Being an old timer as my fried Paul say, I use Permatex Aviation Form-a-gasket sealant liguid part no. 3H which is available at most any auto store. Let it set up a couple of days before installing and adding gas. Be careful what kind of gas you use. "Corn" fuel will trash the seal. Unfortunately we don't have a seal for the midwest fuel. If so I would certainly like to know about it. John
