See full version: A Step-By-Step Guide to Replacing Your Car; s Mechanical Fuel Pump
Your vehicle's mechanical fuel pump is a fairly reliable piece of low-tech equipment. But like any of your car's components, mechanical parts can wear down or break. Fortunately, replacing a broken fuel pump is a fairly simple task that you can accomplish at home in about an hour or two.
Remember, you will be working around fuel and fuel vapors, so be sure that your workspace is well ventilated. Do not smoke, use an open flame, or do anything that may cause sparks or otherwise present a safety hazard. more
Once the old fuel pump has been removed, it's time to prep and install the new unit in this order: [links]
Rant: Citroen Picasso Fuel Pump Nightmare ended. Citroen in their infinite wisdom decided that putting a fuel pump which is prone to packing up inside the fuel tank, which means you have to jack the car up, put it on stands, drain the fuel, remove the exhaust heat shield, move the hand brake cables, remove the four bolts, remove the rubber filler pipe hose, remove the pipes and unplug the cables. Then you have to pull the tank out enough to remove the fuel pump. Or pay a garage to do same. Reassemble having forked out £125 for a new pump only to find the new pump lasted around 2 years before it too gave up the ghost. That poxy tank had been removed no less than six times, involving cleaning the pump filters, and hoping above all hopes that the pump would run and it did for a few miles, then braking down again and again. Well enough was enough. I removed the old pump which also includes the tank fuel gage gizmo. Threw the pump away and secured a steel rod with cable ties to hold the pipe on the bottom of the pump. Inserted the pump-free sender unit. Refitted the fuel tank, cut through the main fuel pipe and fuel pump wires and fitted a 3 bar external pump that works like a dream. Never again will I have to remove the fuel tank and if this pump packs up which I doubt, it will take 10 minutes to change and cost a mere £35.00. Up Yours. Citroen.
Silicone was used to reduce vibration by easing the pump and bracket forward and using a caulking gun to squeeze plenty between the pump and the body on both sides. This will also help to cut down noise and provide bonding of the pump to the car underside, "not that it needs it".
Refill tank with 10 litres of fuel and carefully check for leaks.
Steering Column Shaft: The plastic shield that is installed over the flex coupler of the steering drive shaft will need to be shortened or removed for clearance around the new V8 exhaust system. On vehicles 1982-85 that are having steering drive shaft clearance problems, you may need to make a steering column mounting location change prior to engine installation. The modification is to move the mounting holes on the firewall so that the column will enter into the engine compartment 3/4" further outward than the original location. This will require re-drilling the firewall mounting holes which changes the angularity of the steering shaft and provides additional clearance for the steering column housing. This modification should be done prior to the installation of the new engine. [links]
The installation of a V8 is about 175 lbs. heavier than stock. On 2WD applications, your front suspension will normally drop about an inch. We recommend using a heavy duty shock which will compensate for this drop, or you can change to an extended cab front coil spring which has a greater load rating. With a greater rating, it should raise the vehicle back to its original height. Some vehicles have encountered severe wheel hop & spring wrap up in the rear axle. Some solutions for this problem could be to install a set of ladder bars or kicker shocks to help prevent this problem.
When converting to a Vortec 4.3 V6 in either a 2WD or 4WD vehicle, we have not noticed any difference in vehicle height. Therefore, no adjustments are needed to your vehicle’s suspension. Once completing any one of these vehicles, your front end alignment should be checked. more
T5: The T5 equipped in these vehicles are not recommended for bolting up to the Chevy V6 or V8; however, we do carry a bellhousing for customers that wish to retain this transmission on 1984 and newer vehicles. On 2WD vehicle applications, you should never retain this 5 speed. On 4WD vehicle applications 1982-83 having a mechanical clutch or manual transmission and used with a 4 cylinder engine, you should consider switching to an automatic transmission due to the cable-operated clutch linkage.
