Have a B&M 250 blower sitting on the B&M intake. I get a very slight amount of fuel escaping between the blower and the intake on the rear corner. Removed the blower and the rubber O-Ring on the intake looks to be in good shape. Can I just add a small amount of sealant to this area? What sealant should be used?

Silicone seal doesn't work well in contact with gasoline. I've always used Permatex no.2 but not in contact with an o-ring. Good luck.

Wilks,
You may want to mic that O-ring. It may need to be replaced, or you could go up to the next diameter for a better seal. I also had one of these blower/manifold combinations, and mine came from Holley with the o-ring and a gasket. I elected to stick with the o-ring, and did not use the gasket in conjunction, because I thought it might screw up the blower to manifold clearance for the o-ring. But there is a gasket available, and that may work better in your application, or you might try both.
Regards,
Steve
