I will take out my fuel tank next week to replace the fuel pump and several fuel hoses. Reading several threads I realized I forgot to get a new strainer (I have no in-tank fuel pump). However PET shows a strainer is for models up to '88. Does that mean that models as of '89 have no strainer? I have a '89.

Thanks.

 

The 89 GT got the intank pump as did all 1990> So they either have a pump or the screen strainer. However because of the design of the tank it is best to NEVER change the strainer. It is too easy to strip the threaded ring which retains the strainer and once it spins it is time for a new gas tank since the seal will no longer compress enough not to leak.

 

As Jim say, no wires to tank, no strainer. Leave it alone or maybe at most put some brake cleaner in through exit pipe. Its possible to fix threaded ring if fix is done right but you don't want to try.

 

Ok gotcha Jim, thanks. Let's not push my luck here

So I gather cleaning the tank with hot water and detergent and after that mineral spirits would suffice then.

 

Fixed it for you.

 

Good idea! Will do that and then clean the rest.

 

thats what I was thinking..........its either the intank pump or the strainer

 

Ok update,

Ever since I have driven my car too far on a empty tank - thought I could make it to the next fuel station but couldn't - the fuel pump was making a lot of noise, like metal or ball bearings rolling around in there. The fuel hose from the tank to the pump wasn't looking too good either, so it was time to clean that up.

I cleaned the tank, replaced the fuel hoses, fuel pump and filter, replaced the foam on the tank bracket. All tight and clean. No more fuel pump noise

I discovered I have an intake pump. Since I wasn't prepared for that one, I left it alone. Maybe next time.

 

The fuel pump is a direct displacement pump with rollers located in elongated slots machined into the outer circumference of a cylinder driver connected to the armature of the pump. The cylinderical driver rotates inside a oblong shaped stator. When the pump is operating the rollers move in and out due to centrifugal force following the stator and this give direct displacement to the pump. (This is why it is recommended that if your pump fails, run it in reverse by reversing the 2 electrical wires.

When my initial pump failed I replaced it and when I machined it open I found a small piece of blue plastic stuck between the rotor and stator. Had I run it in reverse it would have freed it up).

Yes when it is operating the fuel pump can make a lot of noise, "like metal or ball bearings rolling around in there".

The pump in my car tends to make quite a bit of noise during a long trip.

Just completed a 860 km trip and at the end ,when in traffic, I heard the fuel pump from inside the cabin. My full trip was around 3,000 km and the only thing I need to do was add a little engine oil. Top speed hit was around 160km per hour with fuel consumption on return trip was 10.7 litres per kilometre and with A/C on the consumption went up to 10.8 litres per kilometer. Average speed for trip was 105 k/h with constant speed on cruise control at 115 k/h via GPS.
