First, kudos that the new fuel pump from Ideola arrived so fast. That gives me two Saturdays to replacement before I kinda really need the car.

Now for the tricky question - is it possible to replace the inline fuel pump without emptying the fuel tank? I ask because I don't (currently) have any way to empty the tank.

The car is a 1982 924 originally sold in Britain. The fuel pump has been noisy for more than a month, but when I went to drive it the other week, it had stopped entirely (it normally gets driven once a week). I haven't done the electrical tests yet - if it's blown the fuse or cooked the relay (again), I can replace that and then get it to a mechanic to replace the pump. (I know - I should check those before posting.)

The other thing that's worrying me is that the car seems likely to have in-tank pump, too. But I haven't had enough of a look to know. Kind of don't want to tinker with that, mostly because I don't have a way of emptying the tank of fuel!

Okay. I'll stop rambling now.

Wade.

A DIY method is to pinch off the rubber hose from tank with locking pliers, preferably with 'flat' jaws. I'm sure the mechanics that speak in algorithms, will have a more professional approach~!

I had thought to simply squash the hose out of the tank - good to see others had done this! I'll be careful of the rubber...

I think such "locking pliers" are also called "vice-grips", FWIW.

You absolutely have many ways to empty the tank, and you should utilize one.

No, I don't have a way of emptying the tank (without doing something illegal like sending the petrol down a drain) - without spending more money. Which I was trying to not do as my next payday is still two weeks away.

But I have some wiggle room and I was not going to rush into this. And there's a carparts place within walking distance. And I could even call on some relatives for additional help and advice.

Why not just borrow one or two of these?

That's what the relatives are for, if they have one. Probably should buy one myself, anyway.

If the fuel hose is so old and worn that it will crack when you pinch or bend it, you should not drive the car (especially in competition) until you replace it.

I have done this job many times without draining the tank. I usually pinch the hose first (in the middle), then disconnect it from the inline pump, then put a bolt into the loose end and secure it with the hose clamp until I'm done with the rest of the job. I like using litter trays from a portable dog kennel to catch any drips during the process. If you're careful not to spill too much, whatever you do drip/spill should evaporate pretty quickly.

I use a 2 inch c-clamp.

New fuel pump works like a charm! And there aren't even any leaks.

I love the satisfaction of having done such a job, but by gum I don't want to do that in again any time soon. At least, not on a 35+ year old car still with the original fuel pump...

So I think I'll keep the '24 for a little while longer.
