Pardon my ignorance: what do you mean by an "airgap" install?

A Hughes FI (fuel injection) Airgap inlet manifold.
Airgap (design) being the Edlebrock carb manifold.

Example in recent thread.

how do you recomend to fix that? I'm not trying to be a smart ***. I honestly would like to know. I installed a hose with fuel injector clamps on my air gap and if I'm at risk of setting a fire in my engine bay, I'd like to know the remedy.

What size (diameter) hose did you use? As long as you used fuel injector clamps and fuel injection rated fuel line, I don't see any issue with it.

I've seen more than one (pics anyway) of trucks burned to the ground because of a leaky fuel lines due to fuel rails or "other than stock" fuel lines. First mod I did after the fuel rails on my Dakota was an on board fire bottle with two nozzles in the engine bay.

I'm carbed now, but the bottle says.

If I do anything to the 98 Ram involving the fuel rails and fittings, it's all coming out for new OEM replacement. IMO, clamps on a EFI fuel line are a made in China band aid.

Do what you feel comfortable with....

In this case, the stock/factory cross-over fuel line leaked. No telling where it was made, as I can guarantee that many of the parts on our 2nd Gen trucks (from the factory) are not made/sourced in the USA. Granted, the fuel line is old which means it needed to be replaced, since it developed a leak. As long as the integrity of the metal fuel injection rails are good (as these are made of very thin metal), a piece of fuel injection rated rubber hose along with the proper sized fuel injection hose clamps will make a great repair for this issue. I can spend my money in many other worthy places in lieu of purchasing the whole fuel injection rail assembly from the stealer and sleep well that my truck is not going to catch fire from a fuel leak in that area.

As an FYI, finally got a chance to measure my fuel injection rail cross over hose size and it appears that its 3/8". Gates fuel injection hose is rated for 225 PSI.

Just replaced my crossover fuel line last night...it's 5/16" fuel injection hose + 2 fuel injection clamps

Whenever I have to replace fuel lines, I usually go down to my local marina and pick up some of their MPI fuel line- the kind that is used in applications below deck (can't remember if it's grade A or B).

It's relatively cheap (~$1 per foot) and is rated somewhere in the neighborhood of 180-225 psi.

Works great and is usually locally available.

Anything metal usually has a very short life expectancy up here due to all of the salt and other crap they cover the roads in during the winter months.
