Fuel Pickup

Hello Everyone
Need advice on fuel sender/pickup.
MTS plastic tank.
V6 lock tab style sending unit with return nipple.

Problem Is the pickup sits about 2 or 3 inches above the bottom of tank.
Anyone extending the pickup lower with a rubber fuel line hose and clamp?
Ok to have rubber fuel line submerged in fuel without disengrating the rubber?
Any other solutions?
Thanks in Advance.

 

Should work, if you are concerned about the rubber you can use brass compression unions and hard line.

 

Depends very much on the rubber. I've had hardware store fuel line fail in one year.

 

A few years ago my fairly new fuel lines cracked and leaked - mostly at the carb connection. This prompted me to do a little fuel line research.
I learned that there are 4 common automotive hose types and many more less common. The differences were in short/long lasting and low/high pressure.
The type is always printed on the hose and looks something like SAE30R6.
R6 - short lifespan, low pressure
R7 - short/high
R9 - long/high
R14 - long/low
None of the above are rated for submersion.
I found that our local FLAPS (except NAPA) had most of these in stock but none of the counter people knew the difference. NAPA had marine rated hose which is much heavier for fire resistance.
Lots of recent changes to fuel hose due to emissions and ethanol fuel.
To the OP - you'll probably have to order submersion rated fuel hose, I think it's R10.

 

Great info Thank You!

 

I use Brake line to make a fuel line, it is easy to work with, just take your time bending it. You don't need a double flair on the carb end, a regular flair is all you need, the fuel pump is low pressure. I took the top off my fuel pump and rotated it so the fuel comes in the rear and out the front, it is a lot easier to plum over to the carb. You have got to bend it to go around the Dipstick tube and up to the carb. You can buy brake line at most good Auto parts stores, it does not rot like rubber dose.

 

I use the nickel-copper brake line for this. Doesn't corrode and is easy to bend. If you have a double flare tool, you can make a "bubble" on the end to help retain a hose clamp. That said, I hate hose clamps and use fittings were ever I can. You could also use the stainless steel teflon lined hose in the tank for pickup line but putting ends on that stuff is a pain in the posterior.
