On our 88 SE tag there is an in fuel line device located on the frame just behind the duals on the passenger side of the coach. It is visible by looking at the frame from the wheel and has a hole in the frame which has been provided for its installation.
Last weekend we smelled gas and traced it to this device which was seeping.
GM does not list this part available anymore. There is a
GM part number - 15598336 available as a Workhorse cross over part for approximately $200.00.
With the help of a kind parts man I found Holley part #12-803 for $30.00 or the Holly repair kit #12-807 for $7.00
The Holly part is identical in apperance to the original and is easily installed.

What is the purpose of this "devise"?
"THE TOY" 88 33'Regal SE Coach #3448
The guy at the GM store tells me its to regulate the fuel pressure created by an "in tank" electric fuel pump which assists the fuel pump on the engine in delivering all that gas all that way forward from the rear tank. I have not previously been aware of an electric fuel pump in the gas tank and still wonder why it can not be heard ticking away when the ignition is turned on.

Some of them are pretty quiet. Stick a screwdriver blade against the bottom of the tank and have someone turn the ignition on and off while the end of the handle is pressed against your ear. You should hear a whirring sound.
Hey Dr. bill h, As a kid fifty million years ago my dad used to do the screw driver trick to his ear. One time after WWII when new cars were hard to get he installed a ton of crate motors in Buicks. Well they came with the dip stick along with other items and after he had installed the engine in one and added the oil he heard a TICK. By mistake he had inserted the old dip stick in the engine. With the engine running and with a screw driver to his ear he moved such around the block and finally touched the dip stick, and WOW there it was. The old dip stick was bent and was touching the crank.
At one time he had 119 new crate engines lined up in the garage ready to install. The shop had a wood floor and oh how I loved to run with a creeper and belly flop like I was on a sled. Loved the noise it made on the wood floor. The office people on the floor below DIDN'T though, but I was the owners KID... hehehe I must have been a real jerk. Don't say it ron.....

I too smell fuel sometimes and after lifting the doghouse cover, know it's not coming from the engine. On my 73 fuel injected Volvo, there is a fuel pressure regulator and there are specs that it must be set to. Does anyone know what the correct fuel pressure should be for a 454 carburated engine?

The Quadrajet runs well with only 2 to 3 psi. A mechanical pump will often put out as much as 6 or 7 psi at idle. With electric pumps, I set my regulators at 4 lbs.
