Back in the day if you took your bus to the dealer for a sender replacement you got an access hole cut.

Any idea what they did to seal/cover the hole? |
Yes I recall that VW Campaign. VW had you use a shift coupler cover plate from a Bug. I did a couple of them back in the day, I thought they looked hoakie. But the instruction sheet provided gave all the measurements required to cut the hole directly over the sender. |

I was recently working on a 1990s Brazil Bus (bay nose, split 15 window rear)
It had a set up like this on it...and it came that way from the factory, as far as I can tell
(It had some other interesting stuff...like what appeared to be a factory zerk fitting on the clutch pedal pivot....) |

Using this thread I cut the hole in my early bay and after replacing my fuelsender have bent a coverplate and screwed it in place.

Reviving and old thread.
My tank and engine are out at the moment so I plan to cut fuel sender access panel while I have the chance. I plan to use one of the marine round inspection hatch. I can't decide between 4" and 6" hatch. If I align it 100% correct then I think 4" should work. 6" would give more room for error. My sender is the barrel type. so it should raise directly upward. The outer lip is about .55 - .65 inches
Opinions?

Don't forget that one might need to gain access with yours or other people's hands, to lever the sender-unit away from its gasket after one has unfastened the small retaining bolts. I have small hands, so I only require a relatively small access hole, but even for me, a 4 inches diameter access hole might be marginal. _________________ Regards.

Good points, I will go with 6" thank you. _________________ -----------------------------------------

this one
https://www.ebay.com/itm/263584464459
send him a request if they show out of stock. He can cnc a couple in a few hours. Lots of people use them and the are easier to install when the engine is out.

I thought about this one but in the end I didn't like the look of the finished product. I found another sold in UK that looked nice but shipping would make it expensive. _________________ -----------------------------------------

you can use a narrow cut off wheel and seal it with RTV. You do not want a plastic solution due to fire risk. There was carpet over that area originally. I had my auto upholstery guy make me a piece that installs with snaps so the whole area is covered. _________________ "Most people don't know what they're doing, and a lot of them are really good at it." - George Carlin |

I agree with sgkent that the cnc fitted panel backer is the way to go. If, however, you really want the round inspection hatch, buy a metal one. The marine stores jack up the prices, but there are some good options in metal:

There is a minimal increase of fire risk with a plastic cover on a 40+ year old vehicle. _________________ 🇺🇸 🇺🇸 🇺🇸 🇺🇸 🇺🇸 🇺🇸 🇺🇸 🍊 🍊 🍊 |
