I am in the process of rounding up the parts to do a dual in tank fuel pump and I have no idea where to buy the boost sensitive switch used to turn on the 2nd pump (I think it is called a Hobbs switch) . And do they come in different boost levels or is it adjustable? Thanks.

 

just out of curiosity i did a search on Yahoo and it brought some links on them

 

Just go to any NAPA parts store. Tell them you want a Hobbs switch. The guy knew exactly what I was talking about with that info. Here's a link:

This thing is adjustable by way of a threaded insert that screws in to increase pressure on an internal spring. I use one to activate my Alky injection at about 5 PSI. Been working great for over a year now. HTH.
