Actually you might also want to look into a Blazer gas tank. On factory 2 door Blazers the gas tank is in the rear where the spare tire is located on trucks and 4wd blazers. A lot of guys in the S10 community like to use Blazer tanks so they can free up space under the cab and bed in front of the axle.

See, that's the kind of crazy useful ideas I look to you guys for!

I took a look on a racing components web page for fuel cells. Looks like 10 gallon tanks are either 17"x17"x9"tall or 25"x9"x12".

The ones that include a fuel sending unit use a GM 90-ohm unit, which I would imagine is compatible with the Chevy S10 fuel gauge.

I used to have an S-10 blazer 4wd with a carburated six cylinder and I swapped out the motor to a tuned port, fuel injected 350 v8 from an Iroc camero. I remember the stock gas tank had an electric fuel pump in it, but it was a low pressure pump, so I had to swap the hi pressure pump from the camero into the S-10 gas tank. The gas tank was pretty easy to take out, so you should be able to get one cheap. I don't know if it's fuel pump will handle deisel though.

Kudos for getting ANYthing done outside in this weather. Again, if you were on the left side of Wisconsin, I'd give you a hand as well. Have you thought about a small storage unit, garage-sized?

Slow_S10, your S-series knowledge continues to amaze me.

Storage unit rentals in my area usually don't want you working on projects in them, and climate controlled ones are extra-expensive.

Nah, I just gotta suck it up and keep working on the project.

I would like to get the electric motor in first, and maybe just have it run on 48V and my old Curtis controller. That would be enough to be able to move the vehicle under it's own power, which would at least let me move it into the garage at times to work on it.

No problem with the stock pump handling Diesel

Since your original engine was multi-port fuel injected (am I correct?) the stock fuel pump probably has too high of pressure output - 55-62 psi is spec, I believe. Your diesel will only want a low pressure (~5 psi) supply - just enough to basically get the fuel from the tank to the injection pump - and I don't think it will like much more pressure than that.

It's no problem though. You can buy small electric low pressure fuel pumps for cheap.

Did mercedes have two fuel pumps? VW Diesels only had one, the injection pump sucked diesel from the fuel tank and more modern ones have a recirculating valve in the housing that the fuel filter screws in to so the fuel stays warmer and it only draws new/cold fuel from the tank at the rate it burns it so the fuel injection pump doesn't have to work as hard.

[mechman600]

Most old mechanical diesels have a "lift" pump - a mechanical diaphragm pump that runs off a bump on the camshaft and draws fuel from the tank. Many have a built in hand primer as well. I wouldn't doubt if Ben's diesel has one and will not need an electric pump at all.

The engine is from an old Mercedes 240D. I think it was a 1985. Very mechanical, nothing at all computer controlled.

Keep all the good advice coming.

Assume that I am clueless about diesels and have no idea what I'm doing, and you'll be close to correct!
