repairing fuel line with high pressure rubber

by Prof. Katarina Bergstrom IV Published 3 years ago Updated 2 years ago

When a leak is found in the rubber fuel line, no amount of duct tape, glue or sealant can fix it properly. This is due to the temperature and pressure of the fuel that runs through the line. The only way to properly repair a rubber fuel line is by replacing parts of the rubber hose, or the entire hose itself.

Why does rubber seep?

The issue with rubber hose is that it will seep fuel if the outside of the steel line is rusty or has a rough uneven surface. Find a clean area with minimal rust. If you can flare the end, the connection with the hose will be more secure. Use the more expensive fuel injection clamps.

Can a hose clamp slip off a straight line?

A hose clamped on a straight non flared steel line can slip off. It is less likely if flared as the clamp can't pass over the flare. If you are referring to steel braid covered hose (popular in performance applications) the advantages are easier installation and replacement of larger than stock diameter lines. Fewer potential fittings to loosen, the "WOW" factor. In cases where fittings are disassembled frequently (between race tear downs) they are more durable.

What is fuel line?

Fuel line is a petroleum-resistant nitrile tube with a covering that resists weathering, ozone and heat and can be used for ethanol-laced fuels and diesel fuel. It should, however, not be used on coolant systems, oil systems or fuel-injection systems that produce pressures higher than 50 psi.

What is a high pressure fuel injection hose?

This fuel hose is SAE 30R9-rated and uses a fluoro elastomer inner liner that will withstand up to 180 psi and 300 degrees. It is approved for all fuel blends including straight methanol, and the outer coating is also ozone- and abrasion-resistant. High-pressure fuel-injection hose can also be used in low-pressure applications, but the difference in pricing may convince you to save it for where it is needed.

What is the rating of marine fuel hose?

Marine hose must have the SAE J1527 Style R1 rating emblazoned on the hose to pass as seaworthy. Marine hose is rated for 40 psi and will work in a pinch for carbureted passenger cars and light trucks.

When a bent filler neck hose is necessary, wire-inserted fuel hose is also offered. It bears the SAE 30R5 rating and can withstand temperatures of -40 to 212 degrees. Working pressure is not relevant, but wire-inserted hose can withstand 50-85 psi, depending on diameter.

What causes water contamination in fuel cells?
