EFI hose and clamps, trust them?

[nonhog]

Just trying to decide if I use hose or modify the sender/pump unit to accept a fitting?

I know its special hose and clamps to deal with the pressure, still seems sketchy?

Success or failures? Post away!

 

[Mgraves235]

I've done it numerous times with no catastrophic failures thus far, but simply due to the nature of high pressure fuel, I would never recommend that anyone else do it.

you can get the special hoses with the clamps on them as repair sections right at autozone. I believe they even have adapters for those since they break all the time. that's the route I would go...

I believe Aeroquip makes adapter fittings to go from factory fittings to aftermarket.

My Subaru came out of the factory with bolt togegher clamps clamps on hoses. They'll be fine, though a stepless Oetiker clamp would be just as good too if you have one that's the right size.

Correct EFI hose clamps are fine. The big difference is the EFI clamps do not let the serrations touch the hose. Remember the clamp does not hole the hose on. It keeps the hose from stretching and pulling over the ridge in the metal line.

Basically. It also as a part that slips under the clamping section so that clamping force is applied around all 360 degrees. Worm clamps don't tighten under the saddle, so that area is prone to cold leaks.

If you do, make sure you by "high pressure" fuel hose that is designed for EFI. Also, I don't know how to do it, but I would put a barb/bulb on the end of the fitting so that the hose can not simply slip off.

So which tube is the main feed line?

 

[nonhog]

Thanks for the reply's !

So which tube is the main feed line?

The one with the ****** (barb?) it was originally a low PSI source from the lift pump to the main (pressure) pump under the car.

I'm using just an in tank pressure pump now. Which leads me to another issue,
Its a 12MM I.D. hose I would need, they are available but not sure how then I would mate it to the hard line. Find a 12MM O.D. fuel fitting?
Oh brother this is fun!

Cut that connection off, add a barb by using a bubble flaring tool, & use good efi hose & clamps.

 

[bwringer]

Don't try to connect an EFI hose with clamps to the smooth metal tube -- the fitting has to have a flare on it, like the large one at the top right.

With a bubble flare, properly sized FI hose and FI clamps, these connections are perfectly reliable.

However, many parts store dolts will happily sell you ordinary non-EFI parts, so be careful.

What was the factory material? Looks like it was Nylon tubing...in which case there are some nylon tubing clamps available...some nylon fittings are designed so that just press-fit is all you need.
I know what you mean by it "feels" better to have a clamp...

 

[nonhog]

The one with the hose is the return. The larger is the fuel line I am working with. I am bringing it to a custom hose shop and possibly have them braze a fitting on the end then my worries are over.

Still good info. Thanks!

use the correct parts that work together and it will be just fine.
