hoobby 271 Posted February 26 Share Posted February 26 (edited) I have been trying to remove what's left of the fuel pump mount bobbings can someone confirm that the body work side is a fixed nut so it just screws in ? as I don't have anything to get hold of just a round flat base Edited February 26 by hoobby Pic Quote Link to post Share on other sites
Exclusive Opel 361 Posted February 26 Share Posted February 26 On a hatchback it's a captive nut (which usually ends up spinning where you can't get to it!). Guessing it's the same on a coupe. 1 Quote Link to post Share on other sites
Mike. 858 Posted February 26 Share Posted February 26 Yes, the coupe has 3 nuts spot welded on the back of the plate that holds the fuel pump. 1 Quote Link to post Share on other sites

1200bandit 441 Posted February 26 Share Posted February 26 It’s a 3/8 thread ( mini exhaust bobbin) is the same ) Quote Link to post Share on other sites
Mike. 858 Posted February 26 Share Posted February 26 Weld a nut on what’s left and use a spanner on it, the heat from welding will help you remove it. 2 Quote Link to post Share on other sites
Mickfrad 248 Posted February 26 Share Posted February 26 Ended up removing the mount to get to them easier and get it all cleaned up. 1 Quote Link to post Share on other sites
GTEPETE 348 Posted February 27 Share Posted February 27 Careful drilling, starting with smaller drills, then go larger. Use the other hole a a guide to final drill size...then remove remains with an extractor or retap the thread...or drill right through and use a nut on the back... 1 Quote Link to post Share on other sites
hoobby 271 Posted February 27 Author Share Posted February 27 Cheers guys as I don't have a welder will go for Pete's idea drill and extract will go on eBay and get a extractor set the other way I thought of was Dremel a slot and use a screwdriver bit both would be handy tools for the future only went to do this as my 2 year old braided hose started leaking on that 90deg turn from pump to pulse damper Finnished that job to find that another hose had started leaking lesson learned and I have ordered some gates barricade to replace the lot. 1 Quote Link to post Share on other sites

Hi execman the only advice I would give is don't do it like I did my shoulders still hurt as said above weld a nut on or drill and stud extract and soak in penetrating fluid over a couple of days.
