If price is important, I'd suggest the Hoover Portable Canister Vacuum. It's going to come in under your price range, and is very light and portable.
It is under the hood on the passenger side of the vehicle. It is black and electric.
You can find video cameras under 250$ in any of the main electronic stores like Best Buy. You can also check Amazon's website to compare prices and get the best deal.
its a diesel, it doesn't have vacuum lines.
a cellphone
Probably would do well with a Timex Scuba Xtreme.
Nikon Prostaff is an excellent variable scope for under $250. Excellent optics, can't beat it for the price.
You can find a Garmin GPS system for under $250. There are many people selling used GPS systems for under $250.
Look for a vacuum leak at the engine.
vacuum pump in a diesel, is a pump installed to create vacuum to assist in opreation of brakes in pickups tha have diesel engines, the brakes are same as any other pickup and use vacuum created by the ngine to operate. a diesel engine does not create vacuum, as a gasoline engine does. that is why there is a vacuum pump added to a small diesel engine on f250 the pump is belt driven, is on the driver side of engine, under the a/c compressor.
You won't get a good e-guitar for less than £250. I think you should set your budget at at least £250 and maybe aim for an epiphone, takamine etc.
No
it works off of vacuum. check the lines coming from the vac pump under the hood for dry rot or cracks
