I’ve got a 2024 f350 lariat with high output 6.7 diesel. I’ve installed a bunch diesel transfer tanks in My 20 years traveling the USA as an IBEW journeyman lineman especially on Highline jobs. I almost always put a toggle switch inside the cab so the pump isn’t hot all the time. I never really gave it much thought I’ve put them in fords chevys and dodges. So now this is my truck so I want it done right so I called GPI I have new m-series 18GPM pump, and I asked about thr upfit switches and the fella said the pump can draw upto 150 amps when starting up so he said to get a 150-160 amp 12 volt toggle switch I can’t seem to find one. Any thoughts from y’all out there. I will say this ive had 2012 f250 6.7 a 2008 f250 6.4 and I have 2010 f350 6.4 and my 2024 f350 with that high output 6.7 and I just purchased a 24” Kaufman tilt top gooseneck trailer and 2016 cat 299d2xhp compact track loader all total trailer and machine just a touch over 17,000 lbs and damn this motor seems like it isn’t working to snatch that trailer and machine down the interstate. It’s kind of impressive

 

Got ya that makes sense that’s why the toogle switch GPI has for the pump is so big it’s got a built in relay. It all makes sense now. Very much appreciate the info. Powerline electrical type stuff I’m a master of automotive not so much. I decided to put a cool looking battery disconnect switch inside the cab as my cut off point it’s rated for like 300 amps. But thanks again for the knowledge
