Go LPG - Our standards
Our Standards


Go LPG are not the cheapest conversion company around.


This is because we do not compromise on either the quality of components or the level of workmanship involved in any conversion.


Here is a brief explanation of our ordinary working practices.........


Pre conversion checks

It is crucial that the vehicle is running properly and has normal service items in good condition before conversion commences. (For instance, some components e.g. spark plugs and air filters must be in better than average condition as LPG can be more demanding). An engine that is 'missing' or running inefficiently on Petrol, for whatever reason, will do just that on LPG.

Note that in the case of single mixer systems, LPG can magnify some ignition or airflow problems and result in 'backfiring', something neither we or the customer want.

If the vehicle is not found suitable, problems can either be solved by us by arrangment or the customer's normal service organisation and the conversion carried out at a later date.


Wiring

All wiring joints and terminals are soldered. We do not use any type of crush or crimp clips. All joints are protected (insulated) with heat shrunk plastic. All wiring is passed through the body using a protective grommet and secured wherever necessary. Plastic cable clamps are used for wire grouping and fixing. Wiring is hidden wherever possible, even under the bonnet. Fuseblocks or holders are fixed in some way.


Mounting of Electronic Components

We make every effort to find the best site for these. Cool and dry conditions are important. They are mounted in a spot least likely to result in any kind of accidental damage and hidden if possible. Where necessary, all plastic boots, grommets are fitted as supplied by the manufacturer, additional seals or protective coverings are made and fitted.


Mounting of LPG tanks

Tanks are mounted by custom made bracketry. Cylinder tanks are most likely to be mounted using strong 'straps' and a mounting base of some kind. Spare wheel tanks have a secondary mounting fitted in many instances as the tank makers mounting points may prove unsuitable or not have sufficient strength in some cars. Panels such as the boot floor (for instance) are strengthened by backup plates so that the tank mountings cannot 'pull through' in the event of a collision. Underslung tanks must have min. 250mm ground clearance at normal ride height. We only use new mounting bolts made of a suitable material and having enough strength for the purpose. For long term security, lock washers, Loctite adhesive or 'Nylock' nuts are used.


LPG tank multivalves

We only use 'OMVL' multivalves because they have an inbuilt fuel control solenoid and are the only type that do not display 'machine gunning' late on in the filling process. In addition, we only use valves that are correct for the size of tank being fitted. Final tank positioning is crucial to the correct working of the multivalve so we use special equipment to get the tank sitting at precisely the correct angle.


Mounting of conversion components

Components are correctly sited and strongly mounted to the car's body or engine. We only use new mounting bolts made of a suitable material and having enough strength for the purpose. For long term security, lock washers, Loctite adhesive or 'Nylock' nuts are used.


Mounting of dashboard switchgear

The best switch position is found by consultation with the car's owner. All wiring is passed through the body using a protective grommet.


Coolant pipework to vaporiser(s)

We find the best flow of hot coolant for the vaporiser and ensure that this is not interrupted by any kind of valve (e.g. cars with Aircon. are likely to have a heater shut off valve which must NOT be in the vaporiser feed line). Only new stainless steel pipe clips are used. If the clip tails are too long when the clip is tight they are trimmed off.


LPG isolating valves (solenoids)

We insist on at least two solenoid valves in every system, one on the tank, (if present) and one inline toward the front of the car. A third valve may or may not be fitted to the vaporiser.

This is a precuationary measure, taken because the vaporiser solenoid valve (if present) can freeze open under certain circumstances. The front solenoid protects against this because it is always capable of isolating the system. All systems fitted by us will shut down the fuel supply in the event of a collision or other force severing the fuel supply pipe, the engine stalling or any other kind of problem that could allow fuel to escape.


LPG filler and supply pipework

Only soft, thick walled, plastic shrouded copper is used for this purpose to ensure maximum resistance to damage, corroison and fatigue. All pipe work is firmly fixed to the vehicle's underbody by the best type of clip for the particular job, and no part of the run is left loose. It is routed well away from moving items such as steering, suspension, exhaust systems etc. so that there is no risk of the pipe(s) being chafed. Pipework is also fixed in the place least likely to result in damage due to grounding, jacking or collision. Underbonnet pipes are hidden where possible and placed in the coolest spot possible. Where pipework must pass through a body panel it will be protected by a rubber or plastic grommet.


Fuel fillers

Fillers are only mounted outside of the car's body and in a position having the least chance of collision damage.

The customer is consulted on desired filler type and position within the above framework. Fillers are only mounted vertically (horizontal fillers are awkward to use and often allow water to be forced into the tank during wet weather) and firmly fixed.


Commissioning the System

The LPG tank is filled, the time and amount of fuel taken noted to see if there are any problems (e.g filling above or below 80% or slow filling). The filler pipework is leak tested. The new installation is set up and the engine run up to full temperature. Vaporiser(s) are checked for temperature (they must be fully hot) and any air bled out of the coolant circuit. Coolant is checked for level. A full LPG leak test is done. Gas analysis is used to fine tune and test driving (often between 50 and 100 miles) begins. Performance and fuel economy are noted along with fuel gauge operation. Switch operation ( GAS - Petrol - GAS etc.) is checked and changeover RPM and temp. noted. If any adjustments are required they are made now.


Is it ready?

We do not compromise. If any anomalies exist they must be cured. Cars are electronically complicated these days and can present us with an unforseen problem. Some cars differ with similar models made only a month earlier or later. Car manufacturers actively prevent wiring and engine management information being available to anyone else but a dealer or agent which does not make the job easy. We get there, but it is not always possible to give an accurate estimated completion date.

We do not send a conversion out to the customer unless we are 100% happy with its operation. Better to overrun an estimated time of completion and possibly (temporarily) disappoint the customer than to send out a job that has the remotest chance of being less than 100%.

If we are happy with the job the vehicle is vacumned out and washed.


Collection by the customer

Every customer is accompanied on a test drive and fully instructed in system operation. Any questions are fully answered either at the time or later if required. Fuel changeover is demonstrated both ways, GAS / Petrol / GAS.
LPG tank filling is demonstrated where necessary. Contact and reporting of any apparent anomaly during the 1000 mile 'bedding in' period is encouraged and acted upon where necessary.

Written 12 month warranty is provided along with a nationally recognised insurance certificate. A list of running hints is also provided along with information about system fuses etc.

Post conversion support does not end there. Although this website may seem to be merely a 'shop window' for our services, it performs another important function - It can be referred to at any time by a customer with a question. Hints for LPG Motoring is particularly useful for this purpose. If the answer is not found the E mail link can be used to contact us. We check for mail at least once a day.


Free 1000 'bedding in' check

We like to check every aspect of the conversion after approximately 1000 miles. If the customer has any questions or has noticed any anomalies these are dealt with now. This ensures a long and trouble free transtion to LPG use.


Warranty

All of our installation work is covered by a 12 month warranty. If we got something wrong, we'll put it right FOC. (That does not happen very often!)

We only buy equipment from manufacturers that give us 12 months warranty . In the unlikely event that a component malfunctions (There is actually very little to go wrong, save electronics) we will obtain a replacement part on your behalf and then fit it for free, ASAP. Please note that replacement of parts is at the manufacturer's discretion, and we may have to send a component on to them for examination prior to replacement.

NOTE that whilst many sources will advise you that only converters belonging to the Liquid Petroleum Gas Association ( LPGA ) can be relied upon, that is most definately NOT the case.

There are many good converters who work to the standards of the British Standards Institute ( BSI ) using the only legally recognised conversion standard in UK, but choose not to be members of the LPGA.
