fuel pump hole
ive been reading all over this site about the fuel pump access hole. well my fuel pump crapped out and i do not have the tools or time required to drop the axle remove the exhaust etc etc. so i decided to go ahead and try out the access hole. it worked out great. all i did was mark it up and cut out the section with a 4 1/2 cutoff wheel. able to replace the pump in about an hour. anyone could do this at home as an easy alternative to dropping the tank or taking it to a shop.
the picture i have is of it almost done i just need to get some more hose then make a gasket and a plate to cover the hole. highly recommended by me. thanks to everyone who helped me out on this one.

Re: fuel pump hole
The downside is cutting your fuel lines. Carb and TBI guys dont care because they operate at a very low pressure
V6/TPI/LT1/LS1 owners risk blowing out the rubber lines or common compression clamp
Most people never have a problem, but the risk will always be there

Re: fuel pump hole
With a little consideration, some AN type fittings means no hose issues.
Re: fuel pump hole
AN fittings require tube sleeves and nuts with the line flared. Pretty much no one does that
Compression fittings work, but again, as the original poster shows, they are rarely used

Things like these fall under the compression fitting category and are not rated for the high pressures of EFI systems

Re: fuel pump hole
No, not those... but even still that particular Earl's fitting is rated for up to 50 PSI, and you'll routinely find other compression type fittings in domestic plumbing at up to 120 PSI, or in hydraulic and brake systems at even higher pressure. It's a matter of choosing the correct compression fitting to match the maximum working pressure of the tubing. I'm still not a fan of compression fittings though because they require the exterior of the pipe to be free of defects, which isn't always the case on 20 year-old cars.
