Lehman SP135 Fuel Pump Removal

[DBG8492]

So today was the day to replace the fuel pump.

I got past what everyone said was the hard part - getting the nuts off the studs - no problem. Didn't even drop one (or both) of them.

However, now that I've got it loose, I can't get it out of there. It's like something is inside the engine grabbing it. It feels like the internal lever is catching on the case before there's enough room to get the mounting bracket off the studs completely. I was thinking about just prying it off with a crowbar, but then I thought I probably should ask someone first...

So here I am - asking someone.

Never mind - I figured it out.

For anyone else who might ask - jam the stop lever all the way forward with something and then turn the crank manually with a wrench 1/4 turn at a time until it pops free.

AND when you're putting the new one in, it goes in bottom first. Insert the lever, then tilt it towards you so the bottom of the pump goes forward first - before you try pushing it up on the studs. If it won't go, keep turning the crank 1/4 of a turn at a time until it does.

Don’t worry about replacing it just leave it there disconnected and just replace it with a 12 volt feed pump, it’s like 1000% better and lasts longer than the old diaphragm pump and cheaper, ticks every box, I did mine 3000hrs ago and haven’t looked back and I have a spare onboard that can be changed in 5minutes if needed to

How many hours did it fail ?
