Guys:

I am new at this. My electric fuel pump stops operating when driving in hot weather. It is mounted near the tank but pretty close to exhaust. I was told that I need to purchase a fuel cell with pump inside and a sending unit. As you might know this comes at a high cost > $2,400.00 from Fuel Safe. Should I build a shield, can one be purchased?

Any recomendations???

 

Yeah- A stock tank and stock fuel pump. Seriously, I've run a 289HP with 3-2V carbs in autocross, never had a problem.

 

I would go back to a mechanical pump of your choice. If you are going to keep the electric one, it needs to be relocated away from the exhaust. That may or may not fix your problem though.

 

Putting the pump in the tank helps keep it cool. I run an external pump with little issue, but I would recommend a bypass style system to help keep things cool. Pumps tend to overheat when they are pushing with little flow. That is why bypass regulators are good.

 

Your pump may be failing and needs a replacement?
A heat shield could also help.

 

The in tank pumps do stay cooler and are quieter too. Thats how most late model vehicles are done.

 

i agree with a bypass type system.

if the pump is continuously running but not pumping much gas flow its going to get hot. they use the gas as the cooling agent which is why you now see in tank pumps.

Carter pump also always preaches about keeping your tank above 1/4 tank. this helps keep some of the sediment on the bottom and especially with submerged pumps keeps them cool and helps prevent premature failure.

 

Replace the pump with a <$100 CARTER pump and this will probably solve your problem.

IMO if the pump is more than a couple of inches from the exhaust you will probably be ok with a Carter pump.

I am of the opinion that the Carter pumps are the next best thing next to a mechanical.

 

Thank you all. I will 1st replace the pump with a carter unit and then see what happens. I am guessing I can but it at Summit Racing?

This will do well for a nice driver car, IDK, say about to 350 HP or so?

They have plenty of others....
