Title: Fuel Pumps
Post by: n/a on March 08, 2006, 09:59:54

Been doing work on my '69 280SL this winter.  Removed the gas tank to be tested and cleaned.  The Fuel pump appears to be original but looks like hell.  It worked fine before the project started.  I hope to get it off and cleaned and inspected soon but my question is:

Has anyone out there used any aftermarket inline type fuel pumps and if so how well did they work for you?

I ask this because these aftermarket pumps can be found for less than $100.00 where as replacements with hardware can easily run $500.00 or so.

Thanks in advance

Many posts on this as indicated--some have had luck, others have not. Problem I think you will find are in finding right combinations of pressure and volume with those pumps not specifically designed for these applications, not to mention the mounting difficulties. The stock pumps can be found on e-bay--new at a price--or you can get a rebuild from a number of suppliers or do the rebuild yourself.

I purchased a re-built pump (long style) that fit my car with an adapter from 300sel.com for about $300.00 as I recall. 1 year warrantee included.

Not as bad as $500 but really not as bad as the pump you built leaving you stranded when out for a ride with your wife!  ;)

Actually, the stock pumps have typically predictable failure modes. They either start leaking or they burn themselves up because the vane is blocked with crud and the armature can't spin. Unless the brushes are down to their very end, I've not seen any that I've rebuilt that show any sign that they quit while the engine was actually running.

My 6.3's fuel pump is currently not working. The car was sitting for 11 years, so I forgive it.
If I can't clean it and get it going this weekend, I'll wire in a pump from a 4.5 as suggested and see what happens.  Also, I just dropped Rusty a query about the parts listed in that other thread for hanging the pump to see what the going rate is. -CTH
