Fuel Pump (Trap door method) HELP!

[MeenZ28]

but now i dont have a reason so since i went to an external fuel pump

How hard is it to convert to an external pump, and whats involved?

[98blackbeauty]

its really not that hard to drop the tank. in the time it takes people the cut the trap door i could have had my tank out and back in. but now i dont have a reason so since i went to an external fuel pump

your correct unless the suspention bolts have never been touched and its been a daily drive. Even with PB we had to cut some of then with a sawsall.

I was against cutting trap door when the pump went out on B's car. His up to that point was a daily driver and getting suspention bolts loose was not to my liking. So did the trap door, got sheet metal at home depot. after that I did a friends car then I had to change mine and also did it.
Myth: cutting drops value.... no one knows it you do good job and screw plate back over hole with RTV to seal it.
Fact: far less time than dropping tank.
If I had a 3rd gen I would do it and flair the line and install a union.
GM should have designed an access panel in the car.

That said though, I definitely agree with James about the fuel pressure and making sure you have a good solution rather than just hose clamps and rubber hose.

agreed ! or have full coverage with a set valued dollar amount

I'm sure the people who are against the trap door method would think differently if they put the car back together and realize a wire got pinched or something didn't go together right and they gotta re-drop the tank to do it all over again. Nah, I'd rather just pop the cover off the trap door and have instant access to my fuel pump any day.

If I were doing it, I'd drop the tank to clean above it

I have never used it on fuel lines, but I am sure it'd be easy since you don't need any where near 180* to use it.

If the trap door is already cut there then, yeah it makes sense to do it that way. Is your car a TPI or TBI? If it's a TPI you really should flare the lines after you cut them and use tube nuts and a union. TPI's run a base pressure of 46psi which is too much for hose clamps. It's a fireball waiting to happen. TBI's on the other hand I believe run in the ballpark of 15-16PSI so its not as big of a deal.

just cut the lines, I did it and it was perfectly fine, no issues whatsoever. Cover the door back up put the carpet back and forget about it, no one will ever know.

That's what I'm aiming to do. I don't think anyone will ever see under my carpet anyway. So I'm not worried about it. Thanks for the info.

Well I'm thinking of just cutting the lines after I release the pressure through the regulator. Then use some hose to reconnect when I'm done, with some worm gears obviously. I'm tired of it acting up and it is my daily driver. I can't afford for it to die and not start back up on the way to work. I've been there for just over a month and haven't missed a day, I don't want to start now. My father said he doesn't want to drop the tank since the door is already there and I agree with him. Just waiting for the weekend so I can get the old pump out and the new one in. Then I can put some sheet metal over the cut out area, some self tapping screws, and some sound-deadener back over it and It won't sound like it was ever there. Thanks for the Advice guys. I will try the plumbing cutters, but if I cannot make a complete rotation, I will be forced to snip them and re-round the ends.

By the way, I don't plan on ever selling my z28 so I don't care if it depletes the value. It is worth more than money to me by being my first car. I still to this day couldn't be happier in the vehicle my parents chose for me for my first car.





Thanks to all who've taken the time to give the advice.

Come on darren don't hack up the new one. It's only like 8 bolts if that to drop the tank. Plus drop it once add your sump and never again do you have to take it out lol. Jk but it's deff what I'm Gunna do when I get bored some weekend. Put the t56 in last weekend and LOVE IT! maybe a sump is do for this weekend.

Just another day on mifbody ...

I wouldnt personally hesitate in doing it again. When I did it the car was my DD so I needed the car fixed asap, now my new car is a second car/toy so I might drop the tank, only because I would also drop the tank for other reason's upgrades and cleaning. But if I needed just to replace the pump, I would do the trap door again.
