Good day all,
Does anyone know the size of the steel supply lines(from OEM fuel filter to CP3)? I'm installing a Vulcan Diesel air horn mount fuel filter system. It came with 3/8" hose which looks too large(I.D.) for those steel supply lines. They look way too small(O.D.). Thanks.

what are you going to do, hook the 3/8 id to the steel od?

 

Yes. I have a vaacum pump in my way so I can't use the fittings. I need to tie into the steel supply line.

 

i can measure one at work and let you know the od tonight,

for some reason this site will not load up at work, every other site comes up fine? all i get is the top portion and the banners.

 

Okay, thanks. If lines are too small, I may have to go with a smaller fuel hose and change the fittings on the filter head.

 

I've got some hose from GDP that I installed my MKII kit with (not big line). I'll double check the size for you as well.

The hose fits over the hard lines and secured with the spring clamp. I haven't had a problem there with leaks.

 

From what I recall, the supply line is 3/8 OD and the return line is 5/16 OD...I could be wrong on that, it could be the ID. I am certain the 3/8 hose you got for your kit will slip over the steel supply line and clamp on...I have done a few of those. Why do you think its different? Did you try putting the hose over the hard line?

Clear as mud hey?

 

i had a truck in the shop today for forgot to measure it, sorry, will do tomorrow.

you could do something like this:

Haven't tried to put it on yet. It just looked like the hose was too large (I.D.)
I don't have calipers to measure so I did measure them with a tape measure. It looked like the supply line was 5/16(O.D.) and the rubber hose (I.D.) was 3/8.

 

That would be good, thanks.

 

5/16" ID

Sorry took me so long

 

Shorts, thanks for your effort. The hose that came with mine is 3/8" I.D. It's okay, I've got it figured out.
