Evening all,

I just purchased a new sending unit and float for my fuel tank since mine was shot. Pulled the old one, set the new one up for bar length, went to torque it down but 4 out of 5 holes are stripped. I can only get one to the 15ft/lbs, the other 4 just spin. Went to crappy tire and got one size up, 1/4 ", but too large. Question is if i get self tapping screws do you feel there would be enough metal filings created to cause a problem?? Last thing i want to do is bugger up the carbs or fuel lines or pump. Full tank of gas and would be alot of siphoning to clean her out too. To self tap 1 size bigger may not even create any filings, unfortunately i wont be able to see the other side to know. Any ideas??

A good in-line fuel filter might solve your problem with the filings.

Edit: Are you sure you should be torquing to 15 ft/lbs? That would likely over torque a 1/4". Somewhere around 2-3 ft/lbs would sound more like it.

Good idea Molaker, that shouldnt change my fuel pressure too much to affect anything eh? I doubt it but has anyone encountered any problems with that? I thought 15 high myself, the dealer was the one that told me 15, i would of thought around 5 like you said, but none the less, i couldnt even get 1 ft/lb out of the 4, lol. :)

Re: Fuel sending unit....

as mentioned the filings ,if any should not be a problem,its not a bad idea to have a canaster water seperator inline as well, filings wont get past that or the inline at the engine,as for the torque,if 15 was mentioned,where the guy got the #from?? but surely it wasnt ft.lbsmore like INCH lbs,with the rubber gsket,I would worry more about just snug em and a bit,those things strip easy and often,ive had to put plates over the original hole and start over
