how to remove the stripped nut!!??

[fordplayin']

cant figure out if i should post this on omc or volvo penta so here i am....the nut from the gas line into the carborator was slightly stripped, now almost totally stripped... it won't budge!! any ideas how to move this before i completly destroy it? i'm thinking we need to clean that screen because of low rpms on WOT, they are only slightly low, at 4000 should be 4200-4800. Does anyone know if this a waste of time or worth the effort to find the screen could be clogged? omc502phue 1995 ford 302 engine... thanks any suggestions welcome. we have tried wd and every wrench we could throw at it Melanie

Well, your model number is an OMC style number, so I would guess you have an OMC. Would be the serial number also starts with a T. So will move this to the OMC forum.

.the nut from the gas line into the alternator was slightly stripped, now almost totally stripped..

Please explain. Alternators do not have gas lines going to them. Think about it.

Re: how to remove the stripped nut!!??

thanks Don:facepalm: i meant carb. been a long day replaced the alt belt earlier... i know it start with omc but it says volva on parts too thats why i was unsure, but since i got your attention Sir do you have any advice for the stripped nut??? i would sure appriciete your expert advice on the question, including the part about the rpm and if this is worth the effort? Melanie
should mention i've already done tune up, its not old gas, changed fuel filter, bottom of boat clean, runs great but obviously not or i would have higher rpms and higher mph we have gone through most of your list on low rpm issues... thank you for that, and Mcleaves helped us do tune up. gained a few mph but no rpm's.

Re: how to remove the stripped nut!!??

You are going to need a new fitting that goes into the carb, it is also what the fuel line screws into.
Probably will need a new line also. If the lines fitting gets egg shaped for any reason, they will destroy the threads.

Re: how to remove the stripped nut!!??

ok so i guess i should leave it be until i get a replacement part... but when i do, how do i get it out is this something i should leave to the pro's or at this point doesn't it matter, just use a vice grip and get it out? and if the tube is ok and we do get the nut out why can't we reuse it? if thats a dumb question sorry! just not sure. thanks Melanie

Re: how to remove the stripped nut!!??

Cut the line off with a tubing cutter. then remove the fitting in the carb and the end of the fuel line.

Re: how to remove the stripped nut!!??

do you think i should just leave it for the rest of this season anyway, and just trouble shoot the rpm issue elsewhere? also does the fact the i can't go beyond 4000 rpm's hurt the engine? Melanie

Re: how to remove the stripped nut!!??

well ignore above post... just started engine its already leaking gas at the nut... if anyone knows of this set up...the gas line goes into gold colored nut then into what appears to be another much larger black nut however, the large black one barley moves and i'm not sure if its supposed to move or not. kind of appears to be apart of carb too. cant tell but looks as if gas is leaking from there not at the gold small nut. any thoughts? which of these two parts is the screen actually in? i'm going to attempt to find the illusive omc parts now thanks melanie

Re: how to remove the stripped nut!!??

There's a fitting which screws into the carb's fuel bowl, the fuel line itself has a flare nut that screws into that carb fitting, the screen (if it has one) is behind the carb fitting at the fuel bowl. Is this a holley carb? Either way it's best to use two wrenches one on each fitting nut to back up one another while applying torque, sometimes a good sharp blow is whats needed to break the nut loose, if it's already messed up then a vise grip may be the ticket.

Re: how to remove the stripped nut!!??

Thanks, but vice grips have not worked and we have been using two wrenchs. yes it is a holley carb. does anyone know where to order this fuel line? its part number 3854059 but its unavailable, as in no longer made, everywhere i have looked on line. HELP please can not go boating with out a compatable part:facepalm: also can i use just a Holley carb replacement nut and gasket or must it be omc marine??? thanks Melanie

Re: how to remove the stripped nut!!??

Holley fuel inlet fitting is not marine specific, the line from the fuel pump to the carb is most likely stainless steel either 5/16 or 3/8 flared on either end, if it were me I would buy a new fuel bowl inlet fitting and gasket that's a no brainer, bend up a new stainless steel fuel line using the old one as a guide, easy for me to say I have the benders and lots of experience bending brazing and fitting line, it's part of my profession.
I wouldn't want to give bad advise but your local auto parts store may have some short sections 24" 30" ect. of brake line with flared fittings already on it in 5/16 or 3/8. you may get lucky, thats stuff bends easy by hand. I'm just putting myself in somebody else shoes that doesn't have the benders and flaring know how thats wants to get on the water, I don't forsee any safety issues using steel brake line, anyone else?

Re: how to remove the stripped nut!!??

ok so i can go ahead and order a Holley carb inlet fitting on ebay or even better at autozone with the gasket, then reuse the screen, we are supposed to have one, after we clean it. i would still like to hear if anyone knows if i can find compatable part for fuel line... But also would be willing to try to use brake line... anyone else think thats cool? how hard is it to bend steel line? i assume you need special tools i wouldn't have? what would my boat mechanic do? have to make something i assume. i'd rather do that them pay someone. if it's not something i'd screw up:redface: thanks so much for your advice! Melanie

Is it the big nut that is stripped or the smaller one?? I assume smaller one

The fuel line on carb engine are usually Steel brake line as you call it commonly 3/8" and the nut type is inverted flare.
Automotive parts store should have premade lines of various lengths with these fittings already installed.
They will work perfectly if installed properly.

Also maybe your local auto mechanic can make one for you from bulk steel line and the end must be double flared with flaring tool

I believe Marine uses brass nut is the biggest difference for corrosion

Re: how to remove the stripped nut!!??

yes the smaller one is stripped however i believe the leak maybe coming from the larger one... not positive, but i know there is a gasket in there so we may have messed that up. either way need to replace the line, we do have a friend thats a mechanic, he possibly could make us one, but he reciently adopted two kids so we don't want to bug him yet i think we'll try the brake line. i think part of the reason its stripped is because its brass. it's so soft. We still haven't gotten the dumb thing off!!!!!! but at this point will probably cut the line. thanks so much for the input! this has been very helpful Melanie

Re: how to remove the stripped nut!!??

The proper tool for hex fittings on metal tubing is a line wrench, it's like a box end but with a small piece cut out. It grips 5 flats of a hex nut instead of just 2 with an open end wrench. But it seems to be too late for that. The next best grip now is to cut the tube off with a cutter (or side cutters), then tap a 6 point socket on to the nut. The larger nut will probably come out too, just place it in a soft jaw vise to remove the smaller nut.

Re: how to remove the stripped nut!!??

we had the line wrench but from the start of this adventure the nut had issues.....HOWEVER... WE GOT IT!!!! WOO WOO!!! It took an act of congress, alot of prayers, and a crafty lubricant called PB breaker!!! but its finally free... may i add the screen was a little dirty some specks of stuff on it however i'd be kind of suprised if it has been our low rpm culprit but maybe?!! its a boat anythings possible thank you all for your advice. we're going to see if our local mechanic can make us a new line, seems the safest! so if it doesn't fix the low rpm's i'll be back for more advice, if it does i'll let you know!!! thanks ,Melanie
