I am planning to change the fuel filter on my 86 convert. Has anyone had experience doing this?

I know the location is in the passenger frame rail. I cannot find any information on this except what is in the factory shop manual. I have been told that it is difficult to do on the convert because the x brace is in the way???

I have no actual experience on the 86, but, its just a simple R/R on the 96.

Just take your time and start unbolting items....use your phone to photograph before in case you lose track of what went where.

Also; use your phone to record all the bloody knuckles...we like those pics....LOL LOL

A further thought on the subject since I'm also going to change my FF on my 94 vert.

It says in the Haynes Manual to relieve pressure in the system by disabling the fuel pump (taking out the fuse), then to start and run the engine until it dies. A further few seconds of cranking to make sure there is no pressure.

I realize that there is a hot catalytic converter to consider, other hot parts of the exhaust system to cool first, and disconnect the battery along with proper ventilation, but is it really necessary to run the engine to drain the system?

Could one not be very careful draining the lines by loosening the connectors and catching/mopping up the drained fuel? I'm concerned that refilling the system would put excess stress on, and overheat the fuel pump

Thoughts.

Cheers

Colin.

You dont need to worry about burning up the pump after the fuel filter replacement. Just cycle the key slowly 3 times, 3 seconds allowed between each cycle, that will prime the entire system then the car will start right up. Technically you dont even have to do that.

Yes, I carefully and safely crack the connections to relieve pressure.

Thank you Strats -- I thought with a little care I could do that.

How much gas will flow from the filter? Will it stop or will gravity feed take over and keep leaking from the filter?

Thanks Al
