Installing a rear tank on my Jeep, kicking around how I want to switch from tank to tank. Did some research on the forum and there where two ways they switched tanks. The threads were a few years old and I have ,I think, a new twist on what was done. I am installing a EFI system on my Jeep and I am using a FiTech Force Fuel system to supply the TB. The way I am doing this, I can use a low PSI In-line pump, the Force Fuel will increase pressure for the TB. One way was the brass six port valve that switches fuel flow. If using a inline fuel pump, there will be a issue about pump placement in the system. I am not big on this system. While talking to Holley about a EFI systems for my Jeep. The Tech/salesperson sent me info about a dual tank system they have. The Holley system uses two fuel pumps, one for each tank. When you switch to a tank, you switch to the in line pump that servers that tank. Holley EFI 534-37 Dual Tank Fuel Pump Kit. On the link, there are install instructions, look at page 2 for wiring diagram, will refer back to this The issue with the Holley system they sell, you get the high PSI Pump. I am very interested in this system and after some research I came up with this. On eBay I found this system. POLLAK Universal 6 Port Fuel Gas Dual Tank Selector Valve KIT | eBay From what I read the Pollark valve is USA made. Amazon has a relay. https://www.amazon.com/Pack-EPAuto-...ay&qid=1609807621&sprefix=87a+,aps,219&sr=8-6 I need input here, the amazon relay link, is that the same one that is in the Holley kit? With this system there will be a pump for each tank, the pumps will be close to the tank which the manufactures like. With two pumps, if one goes out, if you can get gas to the other tank you will be good. I plan on using the Holley Mighty Mite pumps, they have a 12 inch lift. I will have two fuel gauges, one for each tank. I plan on putting fuel shut offs at the pumps and may put six shut offs at the valve so it can be isolated if it goes out. Will this work?
