What should have been 4 days ended up in 1 month before this project was finished. (They had a good reason as the owner had heart issues…..but he is ok now. This company is experienced in USA vehicles and build in our new LPG installation. People living in the USA will think what? LPG is for cooking.. Why would you even want this? Well, here’s the reason; Fuel prices: Gas €1,67/L ($6,85/Gal)—— LP Gas €0,68/L ($2,93/Gallon.
The tanks 110 + 160 Liter (24 + 35 Gallon), have a security filling capacity of 80%. So on hot days the content is able to expand. This means that our filling capacity is aprox. 216 liters. (57 Gallons).
The costs for such an installation are €2.700 but will pay back within one year. (Depending on how much miles you travel/year). We can travel approx. 540km (335 miles) on the 2 tanks.
This is an IMPCO 300 system. At first we preferred the IMPCO 425 series, as this system is able to release more flow (LP Gas) into the carburetor and is therefore a better choice on moments where you will need some extra power. (as in the mountains), but.. the 425 arm that is connected with the carburetor needs to much space under the motor hood. The motor hood would have to be lifted about 4cm to make it fit. (The man said yes to the power but the wife said no to the new interior design). The 300 system fits perfectly and the hood is closed so nothing had to change in the front. In the back I had to flip the water tank and reconnect the hoses to make the 110L tank fit.
Since i’m not a big fan of driving in to the mountains the choice for the smaller 300 system was easy made. It runs like the sun, supplies plenty of engine power and is very safe. This doesn’t mean that the 300 system isn’t capable of climbing. I know GMC owners with a 300 system and they are driving it in to the mountains every year. Another great improvement is that filling up the 2 LPGas tanks takes only a few minutes. Try that with the original GMC connected gas tanks where you have to release the fill nozzle all the time to let the gas flow in the 2nd tank. We placed 2 rear filling nozzles (left and right side). So we’re always able to fill her up.
So this is how it looks now under the future permanent bed. 1x 110L and 1x 160L tank. The bed is our next project -after the window valences/boxes for the wooden mini blinds. The space we had planned for the drawers is not 70 cm deep but only 35cm.
