4th Gen Gas Tank Fuel Pump Hole Access
Hi,
I have done some searched and I only can find most of the information is from a 3rd gen gas tank fuel pump hole cut access. I cannot find any information where I can cut a hole to access the 4th gen fuel pump. I thought I saw some information on here before showing the measurements where the hole should be cut at.
I would appreciate if anyone have any information showing where the 4th gen hole measurements showing where it should be cut at.
Thanks.

Found a YouTube showing how he cut the hole to have access to the 4th gen tank.
Still searching to find more information on how to mark up the hole where to be cut at.

Absolutely no need for a access hole with a plastic 4th gen tank. The tank drops in 5-10 min with the two straps. Thats why its worth while to swap one in if you ever need to do fuel pump swaps, whch generally is not gonna be offen lol a walbro will typically outlast the car

Re: 4th Gen Gas Tank Fuel Pump Hole Access
Did you do any measurement where to cut the hole?

Re: 4th Gen Gas Tank Fuel Pump Hole Access
I'm gonna chime in for no good reason other than open mind.
I'm all about stock setups and originality. But correcting GM's cost cutting measures shouldn't be an issue. GM would rather put the burden on the consumer to pay for tank drop than pay for an engineered access door.
If done right, an access door in a thirdgen is appropriate in my opinion, and particularly because it can be done on the most accurate appearing restoration without compromise to the restoration. The number of pristine cars on this forum where it would not be appropriate is only a very small percentage of the total cars.
Similarly, there are very few pristine cars on this forum where subframe connectors would not be appropriate. But for most of the cars is something that corrects another GM engineering and cost cutting flaw.

Agree with you Saxondale
And there's some hacked up stuff out there.

Re: 4th Gen Gas Tank Fuel Pump Hole Access
Lol i dont think alot of guys on here have plastic 4th gen tanks, else they would know how simple and quick you can drop these tanks.
I can somewhat understand an access panel for a stock steel tank but not the 4th gen plastic ones

I'm not condoning it - but it IS industry standard. If only they used better pumps and sending units....

Re: 4th Gen Gas Tank Fuel Pump Hole Access
This has been my point, most access hole questions I've read here and on Facebook always defend their decision with some form of the "I've replaced too many and don't want to drop the tank anymore" story. Buy a quality part the first time, install it properly, and then you don't have to do it again.
