My Malpassi Filter King worked great and then suddenly started leaking from between the bowl and the body.

The seals semmed ok but bought new ones but it still leaks.:(

Has anyone had this problem and if so how did you cure it?

Hi, had a similar problem after I decided to clean out the bowl / filter after 6 seasons. Could not get it to re-seal whilst still mounted on car. Removed filter and mounted upside down in a vice so that I could check alignment of bowl and seal as clamp was tightened. It looked as if the bowl isn't exactly central it may partially clamp on metal body rather than seal. No further leaks since.

I have taken it off numerous times to try to make sure it is aligned. I have even put a lock nut below the knurled nut to stop it loosening.

When it is off the car it seems sealed and it even holds pressure with compressed air but as soon as I attach it it leaks fuel again!
