Hi Ryan, I have around an in-line Craig electric water pump and I want to use it in my project. To simplify the connection to the engine I decided to use a standard sbf water pump with the front flange for the pulley removed and sealed with a plug, so I can use the water pump connections for plumbing and I remove any risk for the front clearance between the engine and the firewall. This is something that I saw a lot of time ago in a build thread, I cannot remember exactly where, but I liked the idea.
Regards,
Agostino
