Fuel Pressure Regulator - Ruptured Diaphram

[old_master]

Know what ya mean about runways in all directions None of the flight paths are directly overhead here: I'm due South of the 5R approach. Very busy airport and Kalitta is the only passenger service that uses it. Ypsi is a cool old town, a group of us old duffers go there every Monday night for burgers at a bar in Depot Town. Ypsi does have some areas that I don't recommend visiting though GM built automatic transmissions in the main plant at Willow Run until it closed in 2010. They auctioned off the equipment to some company in China, (go figure) and they came and removed it, a few months ago. There's some talk going around town about leveling the building... sad. The Yankee Air Museum, (East side of runways) wants to buy the building, if it can secure the funds. It's one of the largest totally enclosed buildings, a massive place to say the least. Ford just got done completely leveling the Wixom, Michigan assembly plant a few months ago. They built Lincolns there for years! That was another massive plant. Google maps satellite view still shows it standing, NW corner of I-96 and Wixom road.

let me know what you find with the tests and return line.

Will do -
It may take me a few days since it has gotten really cold down here in Tn Highs are only 44* ( I know your laughing now ) and Ive got an OMC Cobra outdrive torn apart in my garage and the shop is full of Triumphs ,so for now I have to work outside .


I know I'm getting ahead of myself , but if the return line is clear will that point to an obstruction in the fuel pump ?


A new fuel pump was put in when all this started along with the new style spider.
Fuel pump/Airtec Spider / Summit Racing Lasted three months then the FPR failed and then two more after that within two days of each other.

Right now its running Ok with the BW FPR but I'm afraid to go very far .

Thanks Greatly !!

44??? That's shorts & a tee shirt around here! We won't see that again until next March... if we're lucky! All the Cobra's better be winterized by now around here.


Provided the return line is clear from the fuel metering block back to the fuel pump module, the restriction has to be in the module.

Airtex pumps are.... uh.... how can I put this.... gently now.... not a good choice at all with this engine, destined for premature failure. I think I've seen every failure possible with them, but a restriction would be a first, nothing would surprise me with that pump.
