Sorry about all the fuel lines posts recently...it's almost done, I swear!

Anyways:

Does this seem like it would work for a TPI application? I was planning on using a short length of it by the fuel tank for flexability.

It's advertised as having a working pressure of 50 psi and a max pressure of 175 psi, but the actual wording states that it's meant to be used for carbureted vehicles. Also, it seems really cheap for what it is; I always thought that FI hose was pricey ($4-5/ft)


And while I'm on the topic: Stock vapor line size is 5/16", right?

I assume you could use that, and get the fuel-line hose clamps like these -



Double them up on each end and it should be OK. You want to find clamps like these because they're solid all around and won't cut through the rubber. By the way, you could just get the 2' length for $6.99 - http://store.summitracing.com/partdetail.asp?autofilter=1&part=GTR%2D65124&N=700+115&autoview=sku - I think your link was the 25' piece.

And yes, the vapor line is the correct 5/16" for the return.

So you think it would work alright for the higher TPI fuel pressure?

I was confused because it was advertised as being for a carb'd app.

And while I could get away with a 2' piece, I figure it's better to get the next 23' for an extra $8...you never know when it will come in handy, especially if I ever need to repair a cracked hose down the line.

yep, I used Goodyear high pressure on mine... no issues at all!

Get the whole 25 feet! You need it in at least 2 feet at the tank location cause even the monte TBI hose it not good enough to withstand those pressures from the TPI pump...

I wouldn't use it. Go to your local auto parts store and get real fuel injection hose. It is really expensive, so you will probably just want to get just enough to do the job. 50 lb working pressure is no where near close enough for a TPI pump.

Yup, the guys on thirdgen are saying the same thing...looks like I'll be taking a trip to the parts store.

the fi hoses I got for my tpi swap, I got at autozone. they have a blue lining in the middle. cost about $2-3 a ft. but I didn't double clamp each end, but I did use fi clamps. ....Bill

i used 6-an braided line from the tank to the tpi and back to the tank i had someone micro tig weld 6-an fittens to the sending unit look's nice but the line was like 170.00 for (2) 20 footer's and i have a accel 110 dfi external pump and h-1 canister filter all an fittens no clamps rich

Steve? Where do you find those clamps for 5/16" or 3/8"? I found some solid worm drive, but not those.

I have seen some of the fi hose clamps at advance auto. there are some listed on e-bay as being made in the USA. Steve

As the other Steve mentioned, a chain parts store should have 'em. I believe I got mine from AutoZone.

Thanks
