'82 245 Diesel- Is there a sock/screen in tank?

I was wondering if there is a sock strainer in the tank of this volvo. I am having trouble getting fuel from the tank to the engine and have blown a bit of air back the line with little results. Does anyone have a thought?

Thanks,
Will

These fuel lines are known to corrode - a pin hole could cause problems you describe.

Yes there is a sock and I assume like the petron version a lifter pump.

However there is a one way valve in the forward feed to stop the fuel flowing back to the tank so how did you get air down the feed pip, the return pipe yeh but not the feed. What pressure did you use ??? Perhaps diesel fits are different but the corrosion previuosly mentioned is very common. Remove the tank inspection cover and examine the pipework. Also see howmany connections there are in the Fuel sender powe connector. One for the gauge one for the lifter pump and a ground is usual. This sender unit costs over £250 do not break it.

Thanks for the response, my brother actually sent the air through the feed line so I am not sure what pressure he used- aprox- US 60 psi.

I imagine that the sock filter is rather plugged, is there an easy way to reach and remove it? If I have to drop the tank is the procedure straight forward?

Based on the comments, I will go ahead and replace the feed line regardless.
Thank,
Will

You don't say whether you have a sedan or wagon. In either event, there is an access hatch through the trunk/load area floor pan. Trunk access is just by removing the carpet. Wagon access requires the removal of the floor cover that leans against the back of the folding seats. The access hatch has four screws in the corners. Remove this and you will see the top of the sender/pump unit. Make sure that you give the area a good clean to get rid of the road dirt that gathers here. Also, the pipes coming out of the unit can be quite fragile because of them being open to the water and dirt from the roads (but perhaps in your location this is not such a problem as it is here). You do not need to drop the tank to do this job.

Dropping tank is not recommended - they have a habit of leaking. Be very careful removing sender/pump unit very fragile/very expensive.
Best of luck.

Ok, I have the wagon and have removed the floor cover. I have the unit loose and can get it halfway out of the tank...at this point the sender unit and the float seem to be at odds and I can't pull any further without the possibility of damage.

Is there anything else that I should know about in this regard?

Aloha and thank you,

If the pipes are discinnected you couls always try to twist it round so that the float arm falls against the main pipe. 'Juggle it about gently' is the only method that I have ever used for this.
