Mechanical fuel pump replacement

Mechanical fuel pump replacement – main image

Older vehicles powered by carburetors were equipped with mechanical diaphragm pumps, which, unfortunately, fail quite often. The most common problem is a leaky diaphragm and worn valves.

Fortunately, there is no problem with purchasing such a pump and replacing it. We can buy on nanodatex.pl, the first international trading platform , thanks to which we can browse the database of free-of-charge purchase and sale ads for used car parts.

In popular cars, diaphragm pumps are usually mounted with two bolts or pins. In order for us to replace the pump, we have to unscrew it, but before we do it, we should secure the pipes so that no fuel spills out. For this purpose, we can use wrenches and simply tighten the hoses.

Before clamping the hoses, remove the clamps that hold the hoses on the pump. If these clamps are disposable, they can be easily broken, but if worm clamps are used, they must be unscrewed using a screwdriver or a wrench if there is access. Then select the appropriate wrench, unscrew and remove the bolts securing the pump to the body of the drive unit.

The next step is to gently pull the pump out. Remember that there is a thermal gear between the motor body and the pump, which in most cases can be removed with the pump. Place the pump in a vessel because it contains fuel remnants that will undoubtedly leak. The next step is to separate the spacer from the pump, at the same time we can remove the remains of the gaskets in such a way that the surface is clean.

Then clean the surface of the pump attachment to the drive unit body. Remember to pay attention during this operation, not to remove the pusher, which is to be located in the body, without the pusher, the pump will not be able to function.

At this point, we can already put gaskets between the body and the spacer, as well as between the spacer and the pump. It is important that the seals are new, otherwise oil leakage will occur. The seals should be replaced every time as they are disposable.

Before installing a new pump, we should check that all the screws have been tightened properly, as it sometimes happens that they are loose. Now all you have to do is put on the pump, put the screws back in place, remembering that you should not use too much force, because tightened screws will deform the pump, which will result in leaks. The next step is to put on the hose clamps and put the hoses on the pump cocks. We can now take the french fries off the hoses and tighten the clamps one by one.

Once everything is installed, we can start the engine. Remember that the pump is dry and therefore the engine may not start immediately. After starting the motor, check if there is a tight connection between the pump and the body and the fuel hoses.

Motorhome accident repairs
When we have a motorhome with a minor or larger accident, or we intend to buy a collision car, it is always worth contacting a proven service, specialized in repairing motorhomes. The Elcamp company from Krakow, known as a manufacturer and seller of motorhomes and a distributor of car parts and accessories, also runs a camping car repair service. Not only what's outside Most often, during a collision, elements of the outer skin of the car are damaged. The effects, however, can be much more serious. It is always worth checking if the equipment inside the vehicle and installations: water, gas, electricity, TV and others have not been damaged. The next stage of repair is the replacement of damaged parts . It is safest to get a specific, new part directly from the manufacturer. Elcamp gives a guarantee for all work performed, unless the repair at the customer's request was not carried out in accordance with the recommended technology. Then no one will take responsibility for any future faults. The biggest enemy of any building is its leakage . The vast majority of motorhomes have "sandwich" coverings. After a collision, check if there are any leaks through which water enters the interior, causing the frame to rot. In the event of damage or leakage of the roof, we will usually have nothing else to do but replace it with a brand new one. This usually takes a lot of time and money. Is the repair worth it? In the autumn and winter period, the workshop is working at full speed. A company with as much experience as Elcamp undertakes every repair of a damaged vehicle . Clients usually ask two questions: about the cost and duration of the work. Unfortunately, post-accident repair can take up to several months . This is due to the fact that not all parts are available "out of stock". The cost obviously depends on the degree of damage to the vehicle or its equipment. When the initial cost , which is usually estimated at the first inspection, exceeds the value of the car, it makes no sense to undertake repairs. Repair expenses are, of course, a river topic. They can be up to 100% of the market value of the vehicle. It is worth emphasizing, however, that it is not synonymous with the actual selling price - well-kept cars, repaired with the use of original parts, reach prices above average market prices. Please check before buying Sometimes it's a good idea to buy a used vehicle. However, be careful with new (or almost new) cars at bargain prices . Then we can almost be sure that they have had an accident. Of course, you can do something with them, but it is important to know about a possible collision. The purchase of an accident motorhome can even be profitable, provided that the vehicle is thoroughly inspected and, during the inspection, as much damage as possible related to the incident (or even earlier) is noticed. It even happens that the cost of post-accident work is lower than in the case of non-damage repair. Remember that previous defects are easy to hide in a damaged car, in which the seller will not allow us to connect, for example, electricity or gas during the inspection, explaining that the installations may be out of order. Sometimes it is of course true, but in this way we are deprived of the possibility of checking individual pieces of equipment. Haste is a bad advisor To find a used motorhome in good condition, you need to spend some time searching for it. It is rare that the first copy that catches our eye is actually worth buying. Here there is a small problem - buying a car abroad. Since we are going far and spending money to see the car, even if it does not correspond to the description, we often decide to buy it anyway. This is a serious mistake. When we are not specialists ourselves, it is best to opt for an advisor - it is an expense much lower than the unexpected repair later. Elcamp's experts often advise on the purchase of damaged or used cars, both at the company's headquarters and at the seller, at the request of customers. However, as they say themselves, nothing can replace a car inspection in a professional service prepared for the comprehensive service of camping vehicles, which has all the necessary equipment. Thanks to them, it is possible to detect defects that even an experienced specialist will not notice with the naked eye.
