how do you guys do it and place the hobbs switch/ vacuum block?

Wire everything yourself? Relays?

Same power feed for all relays to the pump? If so where to feed from?

Which hobbs switch to get?

heres how to wire 2, i would assume you would just add an extra relay for the third pump and wire it in.

what hobbs switch to go with ?

Tanus

you can get a fixed pressure hobbs, that case id probaby go with 5psi, or adj. That would be my choice, one that can adj. from 0 to 10 or 15. Id do more research before you buy anything thou, then relize you got wrong thing or something you didn't need at all

Why not just run two all the time and one on a Hobbs switch? Or possibly two big ones and ditch the hobb switch all together and have piece of mind that you won't have to worry about a Hobbs switch ever failing?

not cool to over fuel

You won't over fuel if you have the proper regulator return line size and a good tuner. We have a truck we just finished that has two walbro 400's on all the time -8 feed and -8 return. With a good tuner the truck has no problems at all. If you run both pumps at the same time you just need a bigger return.

just a question why 2 or 3 pumps? why not 1 good pump? I hear people running these hobb switches and then the switch malfunctions or the relay crapped out or what ever and bam a blown motor. just sounds like its making something so easy into something complicated.

I also agree with this statement but some people don't have the money yo buy a nice sumped tank or find a 98' tank and have someone sump it for them. Plus if its just a street car then the bucket will hold the fuel around the pumps while cornering better then a sumped tank will when low on fuel. Though I do not recommend going any lower then a 1/4 tank on either set up.

And that's great but I still would never trust it. If had a few buddys loose motors because of the hobbs switch not coming on. At least if the pumps on all the time you should know you have fuel coming not possibly if the Hobbs doesn't come on.
