Went to salvage yard and got wiring, straps to hold up tank, filler hose and cap, fuel lines, and bought hoses to extend fuel lines. I have installed tank, installed and wired gauge into dash, new fuel pump in tank, wired. now just need to connect hoses , and finish filler tube. Fill tube is a bit of a problem, but bought 2 inch exhaust pipe, and will fabricate part of filler tube from that. Before I did all that I replaced some sensors on engine, EGR valve, O2 sensor, plugs and wires. MPG went from 5.92 to 10.35 at 60 mph,on cruise, no toad. if that keeps up I could get by with one tank!Re: is it possible to add a second fuel tanktderonne, if I can find a 55 that will work for me it would be great. Do you know what year model you got it from? My rv has twin I beam suspension on front, and as I understand it F53 has a straight axle. I should also point out, it has a low pressure fuel pump in tank, and a high pressure fuel pump on the frame, near the engine area. So any tank I put on will need to work with my type tank pump/assy, or with a low pressure in tank unit of differnt year model. I really appriciate all of the replies and suggestionsRe: is it possible to add a second fuel tankReally, I should fill with fuel and water, load like for a trip, and weigh it. Compare to Max weight rating, go from there.Re: is it possible to add a second fuel tankWould the 55 gallon fit behind the rear axle? I wonder if it's deeper or longer, would same fuel pump/sending unit be used?Re: is it possible to add a second fuel tankwell Fleetman, transflow site only showed options for F series fords, no E series. I may measure area between drive shaft and frame, then go to salvage yard and look for a van with mid tank, and see about getting tank and mounting parts. then add an electric fuel pump and hose to transfer fuel to existing tank.is it possible to add a second fuel tankI am wondering if it is possible to add another fuel tank to my 1991 Fleetwood Flair, on Ford E350 chassis? It now has a tank behind rear axle, about 36 gallon I believe. Has anyone done such a thing?Re: Let's see those older coachesJust got this 1991 Fleetwood Flair, haven't taken our first trip yet. Before it we had a 1976 King's Highway. Probably would still have it if it wasn't a Chrysler product. Kept it 17 years, guess I'll wait and see show long we keep this one! Re: 1991 Fleetwood Flairwell Crasster, fixed it a different way. Blew through with air hose, found obstruction, cleaned nozzles and part of hose with tool used to clean cutting torch tip holes. Now its working well.Re: 1991 Fleetwood FlairI will try that. Thanks for the tip.Re: 1991 Fleetwood FlairThe washer pump has power, so need to remove, the hose leak will be an easy fix. Thanks for your reply.
