P/S pump pressure side fitting size on 97/07. Want to convert to AN fitting (pic's)

[Nasty-LSX]

I am updating the stepside LS FEAD. Removing the holley and putting a billet drive. I got a P/S cooler
for this setup and need a AN fitting for the pump. How do I find the size of the pressure fitting as I dont
have a old hose to go by.

Here is the new swap if you have not seen it yet.

If you are running AN line, you'll need the same fitting for the pressure port on the steering box. I believe the one you found is correct. Iirc, the return fitting on the steering box is a different size, so there are two different size adapter fittings on the market.

Also, if you want to get fancy, you can put a compression type AN adapter on the pump return outlet, and then run AN line on the return too.

got it all covered for the steering box. Just not sure on the P/S pump.

Im going to run twist loc on the pressure side, and push loc on the return side with a large cooler. I know, its over kill. but it will also look good.

Ok so I got the correct size. its not 18MMx1.5
the correct size is 16MM 1.5

are you using hydroboost? If not you would benefit from a type II (TC) pump, but that has a different fitting aswell.

No Hydra boost. The Holley mid mount was Type II.
