I had swapped my 87 5 speed fuel pump with the 88 months ago to make sure it was ok. I put the 88's back in today (only 2 year old pump). I can't get the banjo fitting to stop leaking (slow drip). It was a bitch to get the cap off, could I have twisted the banjo fitting?
Is there another way to tighten the cap and be able to hold the pump besides using the clamp?
I will order some more washers, these looked new, had them laying around. I took them back off and sanded them with 400, still leaked.
Any suggestions?
Thanks,
Glenn

if you use an old sealing washer it will usually leak you could try to reanneal the sealing washers, by using a torch to reheat them this will make them soft and then they should seal.
WARNING dont go anywhere near your car with the torch, and always have a fire extinguisher ready to put out a fuel fire

if those crush washers are copper you can do this, if they are aluminum they will evaporate the moment you touch them with heat.
dont ask how I know

You already got the new ones ordered so I would go with them. I have reused the washers on both of my 928's when I had leaks from the banjo. The coppew becomes work hardened over time from being compressed. I heatet until glowing and then air cooled. I then sanded until bright and smooth and all is good. I would not suggest others use my tightening method as the results can be bad if you go to far. When I did mine I could not find a good way to get leverage on the pump to get the banjo bolt good and tight. My 3/8 impact gun has a fitting so you can turn down the air pressure and get very little torque on the bolt. I turned it way down and gave the bolt a few blows to seat it good.

Glenn,
Bring the car over to my house, leave the keys and I'll take care of it. I should have it fixed in a year or two! Yes... I know... I'm a kind soul with a big heart. BTW NAPA has most common sizes of sealing rings - including metric. I just bought what I needed for my PS for $0.69 each.

I find that its best to assemble pump and filter on their carrier on the bench - easier to get things done up tightly and correct than while fighting for leverage and access under the car. The only overhead is the R&R of the pump electrical leads, which need a little care, and the correct small spanners/wrenches. Can you say 'magneto spanners' ?
