Supermarkets often sell petrol as a loss leader to entice motorist/customers into their store. A supermarket chain can buy in bulk and get a discount off the fuel suppliers.
Depending on the supplier, many do not routinely offer large retailers discounts based on sales. Most non oil producing countries find that the supply is governed by the import supplier and the prices for outlets fixed (basically heres the price take it or leave it). Retailers use a system as stated above of either "loss leader" or as in most cases "off set pricing". The latter means that high demand items can be used where a very small price is added the normal selling price. This is undertaken across the range and in that way profits can be better managed whilst appearing to show the retailer making little on the petrol revenue.
It depends on what is wrong with it an d what part of the country you live in.. Call a couple of local garages.

One can find the most expensive but reliable fuel filters at a local car dealer or automobile repair shop. Amazon and eBay have this product too although while cheaper, they are less reliable.
At this point of time, bio fuel is about the same price as regular fuel. In certain countries, it is slightly higher in cost.
If a new, cheaper fuel was developed, it would greatly affect OPEC. OPEC would probably have to lower its prices in order to remain competitive.
In general it is cheaper to travel by train. It is much cheaper to fuel a train than it is a plane and this would account for some of the expense involved in flying.
Truck fuel is cheaper than jet fuel.
Cheaper to built and therefore cheaper for the consumer to buy than a diesel. Fuel costs less than diesel.
Jet fuel is diesel fuel, which is generally cheaper than high-octane gasoline.
$660.00 for the pump (might find a cheaper one but some are junk, be careful), 1 - 2 Hours labour @ whatever local rate
They each have their pros and cons. The Diesel will last longer, use less fuel, and has more pulling power or torque. The petrol is cheaper to build, fuel cost less, and is cheaper to repair.
its probally your fuel regulator, cheaper and easier than your fuel pump too!
