Im using a Aeromotive A700 pump

its 8 an inlet and 6an outlet (female) but there is no where for the top of a fitting to seat.

do I have to put a copper washer or anything between the filter and the pump (filter has AN ends)?

also, would drilling an alluminum AN fitting cause any corrosion problems?
I got some delleroto fittings from summit for my fuel rails, but they got really small on one side. So I drilled them out.

 

post a pic, I think you have o-ring boss ports.

 

yeh, your probably right, I had that style on my regulator.

I would post a pic but its a hundred miles away, im at school.

My pump is mounted above my fuel cell, so I have to make sure its right before I mount it.

 

its probally pipe thread to an. I know that the two i run on mine are. i forget what size pipe thread it is but its not a problem to order the fittings.

 

AN O-ring fittings if it's the same filter I have. I know of one person that has used teflon paste on a regular AN fitting and seems to work, not what I would recommend though

 

You dont want to use the AN fittings with the round end, the orb fitting will have a o-ring and a washer.
