I've shopping around a bit for a shop to install a Wesbasto into my 92'. Quotes range from $1500-$2000 for the labor and $1200-$1500 for the kit. It seems like a pretty steep bill for something that shouldn't be too hard on these old trucks. The only worry I really have is drilling into the fuel tank for the fuel line, I'm assuming ill have to drop the tank to be able to drill into it. I'm looking for any advice on how to go about that or if a T into the existing line is a better option.
Coolant wise my plan is to T into the hard lines just above the exhaust manifold and mount the Heater near the air intake.

Thanks

 

Another option if you have an engine hoist is lift the bed off. I've dropped the tank on my '93 & also pulled the bed off. If I have to do again I'll pull the bed its a whole lot easier.

 

My preference is drop the tank. Makes it easier to inspect and clean. Drilling the tank is fairly easy. I did my 01 to install a draw straw for a FASS fuel pump. Tapping into the existing fuel line may not be a good idea unless you upgrade your fuel lines to something larger.

 

Is the Webasto so that your truck stays warm without plugging it in? New to the cold weather climate and I've been plugging in.

I've only dropped a tank on junkyard truck and the tricky part is disconnecting the fuel lines on top without damaging the lines or the plastic dingus fittings. I've been putting off doing my fuel sender because of it. I'm thinking I may cut the access panel (I think theres a sticky about it) in the truck bed, to disconnect the lines.

 

We had WEBASCO's at the county I worked at, They have a pump that circulates coolant, run on 12 volts and fueled by diesel and have a thermostat you can set what temp. you want it come on at. The down side is, if you don't drive it often enough it will wear down the battery. Some of the plow trucks sat for days at a time not used & the batteries would be dead. They heat well though.
These were on medium & heavy duty International & MACK trucks.

 

I've kicked around the idea but coming out to a dead battery isn't my idea of fun. Especially when it's -20°. I either park where I can plug in or don't stay parked long. A winter front works wonders for holding the heat in.

 

I don't have temps below zero very often, but plugging in the block heater is by far the best way to keep the engine warm, I don't have grid heaters any more and my truck will fire off like an 80* day at 5*, and already have enough warmth to defrost the windshield.

 

The plastic angle fittings are replaceable. I replaced both of mine and I have a few left over.

I cut a square hole in the bed over the fuel pickup assembly to access mine. Then I welded some sheet metal and put threads in it to allow me to have a removeable cover for when I have another idea as to why my truck starves for fuel at 1/2 tank.

If you want just drill a hole in the plastic of the pickup assembly and run whatever extra pickup you need.

I think I would just T off the fuel line
