Hey guys,

It's finally summer again here in the UK and my 89 Barth Regal is raring to hit the countryside!
I'm trying to get my fuel gauge to work, it's been stuck on full since I bought the vehicle.
We've tested the gauge and resistance and all appears working at the cab end, so looking to drop the petrol tank and replace the sender.
Would anyone have any details about the fuel sender? part number specification?
I don't want to drop the tank just to take a look at the sender, and then be off the road for several weeks waiting for the replacement part to arrive from the US.

Additionally would anyone have any photos of the engine layout for this model? Trying to understand if the air filter is supposed to be directly on top of the engine or whether it should be further forward in the engine bay of the end of a metal tube?

Thanks in advance

A while back I had problems with the in tank fuel pump and sock filter in my 86 Regal. For one tank I was able to cut a hole in the floor in a discrete place to remove the sender and fuel pump assembly. I am not sure how similar this is to yours. (Sorry no info on senders, mine were working, pumps bad.)

The other tank I did from below, never got it all the way out. (BTW, my Regal was a tag axle and has more clearance above frame...)

American fuel senders typically use a standard 5 screw mounting called the SAE pattern. Any universal unit that has 0 - 90 ohms will work, if the length is correct. The pickup tube should be 1/2” above the bottom of the tank. You adjust the float to match what was the old unit pattern. You do not need any filter sock in the tank, but you should have one filter before the electric/mechanical pump and a new filter in your carburetor inlet. I regularly dropped the tank and it is not difficult. Mine are held in by steel straps and once loosened two people, or one with a jack, can drop it. It is not heavy unless if is full. You should siphon it to empty. After it is out carefully inspect it for debris inside and rust. If it is rusty you can try to match it to the chassis of the coach. I did have it renewed by sending to specialist that cleans and coats the inside with an epoxy that is impervious to fuel. There are lots of universal, adjustable pickups available but be sure to count the number of inlets. You could have 2, 3 or 4.
