Hey there,

                       I just bought this 1986 Subaru GL 10 Turbo as a project car.  The guy I bought it from did a bunch of work to it : head gaskets, water pump, timing belt, plugs and wires, coil, axels.  He said he thinks the gas tank needs to be cleaned or replaced as the car had a starting issue when it got below half tank.  I haven't had any starting problems.  My problem is that it loses power at higher RPM.  It bogs down and acts like it is starving for fuel/air.  I replaced the fuel filter and it helped a little bit but still has the problem.  Should I replace the gas tank?  Or could it be the MAP sensor or the ECU?  Thank you

Maybe the gas has started to turn bad.  Have you tried pumping a small amount of gas in to a glass bottle to look at it? There could also be moisture or corrosion in the distributor cap.

Sounds like a weak fuel pump.

my original pump on EA82T was on its last legs - did not make it to near 4800 as it would die (watched the pressure gauge taped to the window drop from 36 to 10 psi) as I asked anything more than take off.

 

I cleaned my tank, dropped diff to last threads on moustache bar I think, undid all hoses and clamps, did the hydrochloric acid clean up, neutralised it with carb soda, washed out heaps of crapola. Was good for new fuel pump - is usually part of warranty conditions of a new pump anyway.

 

Could be a few things

I had a similar problem (my wagons not a turbo though) and my air filter looked clean.  But after I put in a new one....it really helped with my power.  Hope that helps. 

Thank you all for your feedback.  I think I am going to replace the gas tank and fuel pump and see if that solves the problem.

So I am thinking of replacing the fuel tank myself but not sure if it is beyond my capabilities.  Can anyone give me a step by step on how to replace the fuel tank on my 1986 Subaru GL 10 Turbo wagon?  I was thinking I would replace the fuel pump at the same time.  Thank you

I wouldn't replace the tank unless it's leaking. they don't fail "just because". Fuel pump is on a tray bolted under the body in the rear, so you can replace that without touching the tank.
