Does anyone have any experience on what parts to purchase and how to instal a fuel pressure sending unit and gauge? I would like to see the pressure at the drivers seat.
Thank you for any input.

You can use an oil pressure gauge and compatible sending unit. Similar range of 0-80 lbs with oil pressure unit. Very simple.

Will the oil sending unit hold up without leaking? Isspro list a 0-70 electric fuel pressure gauge in their catalog, but no sender. I call to ask about the sender and was told that they had tried 2 different vendors, but neither could produce a sender that did not leak. Jack |

Autometer make a whole range of fuel pressure gauges. They are mechanical and there is an isolator available so that fuel is not at the gauge inside the vehicle. The isolator is fitted at the point where the line would come through the wall into the vehicle.

What would you gain from this exercise?

Yes, the sending units hold up. At least the one on my Prevost has since 1989. What this will accomplish if installed between the primary and secondary filters is to tell you which filter is plugging up and needs changing. If fuel pressure drops from normal, the primary needs changing. If the pressure rises from normal, the secondary needs changing. Beats trying to change and prime both on the side of the road somewhere. They can plug up incredibly fast sometimes. Been there, done that in Quebec where no-one wanted to speak english to me and my spare filters were in the shop in NH. Getting one filter was bad enough, I didn't want to even try for the other.

Also Fred I understand that low pressure can mean not only blocked fuel filters but leaking fuel from an injector crossover fuel line.I had a past problem with a line leaking fuel into the sump.I was lucky and noticed I wasnt using any oil on my 671.Began to check it was,nt water but fuel from the overhead.I understand 71 series engines do have possible potential problems here and I wanted to be able to monitor the fuel pressure from the bridge.

ON boats we use the Murphy Gage that measures diferental pressure between the inlet & outlet of each filter.
Rings a bell , if you wish.
The WEST marine fuel prefilter is about $20 - $30 bucks (fancy funnel with water & gunk removing screens) and should ALWAYS be used for filtering in 3rd world socalist countries like Queerbeck.

Geno's Garage has Westach FP gauges in 0-15 and 0-30 PSI for $69. Comes w/ sender. It is an electrical sender. Just run a short (18"+) fuel line to the sender to isolate it from engine vibration and wire to the dash. They have various mounts for gauges also. I have the 0-15 psi in a Dodge CTD and it has worked fine for 2 yrs now. They are super folks to deal w/ and can be reached at www.genosgarage.com or 1800-755-1715. I'm not afilliated w/ them, just passing along the info on a good vendor. |

My fuel pressure guage normally reads about 60 lbs. It is a 0-100 psi guage. (8v92DD in 80 Eagle)

60psi? Wow! Guess Geno's can't help you there. You can contact Westach direct at 800-400-7024 or www.westach.com. They do make a 0-80 fuel pressure gauge and sender. They usually don't carry anything in stock, so I'd ask them if any of their distributors carry them. They will make it for you. You just have to wait for normal production cycles. They are a little lax in the customer service dept. It may take a little persistance when dealing w/ them. |

Westach instruments are generaly available from aircraft supply houses such Wicks (www.wicksaircraft.com) or Aircraft Spruce and Specialty. I have used them in a couple of homebuilt aircraft but I am not impressed with the quality. |

You guys got the cash, if you are buying fuel in La Belle Province! (aka Quebec)
Seriously, for the less experienced busnuts:
Buy your fuel from locations that have a high volume of sales and are on travelled corridors.
There is no free lunch, cheaper fuel may cost later...
Where are the truckers fueling up?
Drivers trying to make money with their equipment won't fuel where it costs filters!
If the tanker is present, don't fuel, as the junk in the bottom of the storage tank gets all riled up by the fuel drop, and you'll inherit some of it.
It would be prudent practice to carry at the minimum one complete set of fuel filters for your engine. Less chance of being gouged on the price, if they are even available locally, WHEN, not if, they get clogged.
After all, they will eventually. They aren't in there for nothing!
happy coaching!
