Fuel Pump assembly studs

[eclipse90gsxt]

Well I installed my walbro 255 a long time ago. ANyone who has done this knows there is 8-10(I forgot exactly) with nuts on them that hold the whole assembly into the tank. Having my luck 2 of the x amount broke off. This is a problem because the assembly/tank don't seal all the way and I have very long start ups, and a good smell of gas in the car sometimes.

My question..does anyone have any ideas of what to do? If I remember the little studs are actually connected to the gas tank, and I really don't want to get a whole new tank or used one and put it in. I also don't want to risk drilling into the tank(empty of course) and using bolts/nuts. That would probably work but I would need to catch all of the shavings.

Any input?

the longer the car sit's the longer it takes to start? if so then your losing fuel presure

Yes I know that because of the leak at the housing. What I am asking is does anyone have any ideas as to fix my problem. The problem being 2 of the studs are broke and the seal is broke at the assembly/tank.

I broke one of these studs when installing a fuel pump. I also have long start ups after the car sits for any extended period of time.

I'm thinking about trying a screw extractor to remove the broken stud and replacing it with a new one. The studs are small, 6mm or less. I will also try replacing the gasket that seals the assembly to the tank.

I'll let you know how it goes

I had one of them break off also while I was installing a Walboro 190 earlier this year. I didn't have any problems starting up at all though until about 3 weeks ago. You might want to make sure that the o ring on the fuel pump itself is sealing still because that's what my problem was. The o ring looked fine when I took it apart so I just put everything back together and made sure the o ring went in right and now I don't have any problems starting.

I don't think the broken studs are your problem. As far as I know, the fuel pump assembly doesn't have to be sealed to the gas tank to maintain fuel pressure. Mine has had a broken stud for about 9 months and it's never given me a problem except for smelling gas sometimes. I fixed that by just using silicone glue to seal the black lid back up like it was before I took the pump out.

The studs are part of the gas tank so the only way to fix them is to replace the gas tank or to drill the broken ones out and put new studs in. I believe Taboo made a post about how he fixed the studs on DSMTalk a long time ago, but I can't search for it since DSMTalk isn't online now. If you drill them out, just make sure to keep the area wet with water or something so that everything stays cool and you don't get any sparks while drilling.

Thank you for the replys. I am going to go take the whole thing out and check everything including the o-ring. I will probably just try and get the old studs out and put new ones in.

You COULD drill out the studs...

Or, just do it the easy way and run a couple of self tapping sheet metal screws through the pump top and into the tank. Works like a charm.

Forget screw extractors, looks like i'll try drilling out the old stud and using a self tappping screw in its place.


Its tough to well whether the O-ring is seated properly. I'm using a 3000GT denso pump shaped exactly like the stocker, any tips on installing the O-ring?

Just make sure it's lubed up with oil or something before putting it in.
