I am undecided I have a 24v manual trans donor or a 12 v donor truck both trucks are equal in miles about 200K so basically which motor should I go with? its all going into a 90 f350 I just plan on towing no crazy HP or anything. So please give me your opinion I know the lift pump is weak on the 24V is there a better option other then FASS and is the VP44 a good pump otherwise what about the electronics of the motor they scare me that is why I got the 12V to begin with but anyways thanks for your time

12 Valve, no electronics at all to run ( well, except Starter. ), simple as a stick, in my opinion, the way to go.

If you want something easy to power up and back down, the 24V might get the nod. The VP44 is not what you would call a great pump.

 

I love my 24 valve, but the answer to your question is 12 valve, not a doubt.
