Replacing Fuel pump and frozen check valve....

[Ben Swann]

You need to grind down a good quality 17MM wrench to make thin engough to fit behind the
banjo bolt.  I did this many years ago and have used this "special tool'  many time
since. Use this and 19mm deep well socket to break the fittings - may need combinations
of 14..19 mm sockets and wrenches.  

Don't be afraid to sacrifice a wrench or screwdriver to make a custom tool - it pays for
itself time and again.

Be carefull not to bend/crimp the line.  If you need to mate good quality fuel injection
hose by sliding over plastic hose and double or triple clamp.

Well, the fuel pump finally quit on my trusty '85 4000Q. I have a good working spare
pump off a parts car and started in on the job only to find the check valve frozen to
the banjo bolt on both pumps. It looks like I can get the  bad pump off by destroying
the electrical connectors on the pump body (unless  they are removable .....I doubt it)
but getting hold of the little, tiny, skinny crammed between the two electrical
connectors check valve nut looks  almost impossible. (another example of superb German
engineering). 
Looks like I  might have to fabricate (grind down) some sort of wrench to get on the nut
....needle nose miniature vice grips maybe.........  So last night I soaked everything
with PB Blaster and went to have a beer in the hope that there might be a BTDT easier
way to accomplish the task, if it can even be  done.
 
Thanks,
Jim
